Hello :)

Im doing a project for work: I want to make a sign for our office that automatically activates, when our daily meeting starts and turns off when it ends. Im using a D1 Mini and already made it, so i can manually turn the LED on the breadboard on and off via WiFi. Does anyone have some advice for me? (its my first programming project ever)

Hello, I am designing this circuit for a diy smart servo board. i am planning to solder everything to one PCB. If i do it like this i would have to burn the bootloader to the Atmega328 via the SPI pins with the MCP2515 connected to the same pins. My question is could i burn the bootloader to the Atmega without damaging the MCP2515?

Hi all, I was working with some Arduino stuffs and I think I screwed up, because at some point all the USB port of my laptop have gone out.

I was trying to control a servo motor (MG996 360°) with a NodeMCU v3 board.

The NodeMCU was connected to one of the USB ports of the laptop, and the servo took 5V from the VU pin (the pin that provide power directly from USB of the board) of the NodeMCU.

But the problem it's that I have then connected the ground of the servo to another board: an Arduino Mega 2560 connected throught USB to the same laptop.

That because I was trying the servo first with Mega board and then with NodeMCU and at some point I found myself in this situation without thinking.

Initially did not seem to cause any problems, but at some point all the USB ports of the laptop have gone out (the laptop instead did not power off) and now, even after a reboot, USB ports don't even provide power, completely dead.

It's possible that I have burned the USB controller of the laptop?

Please bear with me; I never programmed Arduino before, but willing to learn... I am currently conceptualising a macro keyboard which can also writeout a password. To make it secure enough, I'll need a fingerprint reader so I can do something like "if fingerprint OK then writeout 'Pa$$W0rd' ". But I need it also to keep the program non-readable. I read something about lock bits; would these make this possible? It's okay to rewrite the sketch, but it should be impossible to unplug the keyboard and read/disassemble the embedded code.

Is this possible with Arduino?

Working on a project that needs to replicate an AC sensor's output, which provides 0-200mV AC (60 Hz). The load on this sensor would be 2 Ohms which means the current will range from 0-100 mA AC. The basic plan is to use one Arduino to read the sensor and make the value available over a local network, then a second board will replicate that sensor voltage out to the equipment to which the sensor would normally be directly connected.

From what I can tell, the current to be supplied by the second board exceeds the maximum current limit for most Arduino boards themselves so external components will be needed. But I'm having trouble identifying an out-of-the-box component that will supply that much AC current, that little voltage, and also be controllable from an Arduino board. Any suggestions on components that might work or how to do this? Any help would be appreciated, thanks.

Hi,

I’m looking for an N-MOS that I can control with my ESP32. I’m using a IRLZ44N, but the drain-to-source voltage doesn’t fully pass through.

These are the connections I have made to my screen but I don't know why it doesn't show any message. I only have a breadboard, an Arduino Uno board and an LCD screen. The model and program are Arduino 1.8.0 and the screen had already worked before. What can I do?

I am working on cobbling together a marquee to fit a very specific-sized area. I was able to work out that I can connect eight MAX7219 8-in-one modules and two MAX7219 4-in-one modules together in a rectangle to fit the space precisely. Attached is a crude diagram of the resulting Matrix collection (drawn vertically).

Regarding power supply, what sort of external power supply would be required to run this?

How much memory would likely be needed to drive this? Would an Arduino Uno suffice, or do I need something beefier?

Here are the 8-in-one modules I am using: https://www.amazon.com/dp/B0BXDNCVRT?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

Here are the 4-in-one modules I am using: https://www.amazon.com/dp/B07FFV537V?ref=ppx_yo2ov_dt_b_fed_asin_title

I've had very little experience with Arduino, but I've decided to learn as I go and do a DIY project to make a custom display for a collectible of mine, complete with LEDs and music.

What is the best audio amp chip for this purpose? I’ve come across the LM386, which seems popular, but I'm open to other suggestions. Ideally, I'd like something that can drive a CE38MB-32 speaker, which has a 32-ohm impedance.

Any recommendations or advice would be greatly appreciated!

Hey,

I'm trying to create a project using FastLED and Arduino but I'm getting stuck by trying to set it up.
The set up is realy simple but when I include the FastLED library and set up a button with pinMode() then the ESP gets in a bootloop. I'm using FastLED instead of NeoPixel because I want to control a lot of LEDs and my ESP can't handel that. But it does work for FastLED.

Microcontroller: ESP32-S3-Wroom1
IDE: ArduinoIDE
Arduino Board: ESP32S3 Dev Module
ESP board library: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
FastLED version: 3.7.8

Check the following code that I'm curently trying out:

#include <FastLED.h>

#define LED_PIN     18  // Try a different pin for LED data
#define BUTTON_PIN  21  // Use GPIO 21 for the button

#define NUMPIXELS   256
#define BRIGHTNESS  20

CRGB leds[NUMPIXELS];

void setup() {
  Serial.begin(115200);

  // Set pinMode before FastLED setup
  pinMode(BUTTON_PIN, INPUT); // <---------------- It crashes here! But continues when removed.
  Serial.println("PinMode set for button.");

  // Initialize FastLED after pinMode
  FastLED.addLeds<NEOPIXEL, LED_PIN>(leds, NUMPIXELS);
  FastLED.setBrightness(BRIGHTNESS);
  FastLED.clear();
  FastLED.show();
  Serial.println("FastLED initialized successfully.");
}

void loop() {
  leds[0] = CRGB::Red;
  FastLED.show();
  delay(1000);

  leds[0] = CRGB::Blue;
  FastLED.show();
  delay(1000);
}

This gives me the following error:

Hello guys,

I am trying to move a stepper motor with a TB6600 controlling with a potentiometer-joystick. Depending on the value of potentiometer it will move in direction, the opposite direction or stay still.

I have done similar projects before, but this time the motor won't stay still unless I disable the enable pin but the motor will lose its position.

In my previous projects I used a different wiring ( Arduino's groundings to driver's grounding, and pins to driver's pins) but with this TB6600 I bought recently I can only make them work with this wiring

This is the wiring and the code I am using:

https://preview.redd.it/ukglaq86ryvd1.png?width=1163&format=png&auto=webp&s=7d94d09cf7fcdb59cdba8dc6369fba4aa0443387

#define BASE_STEP_PIN      1
#define BASE_DIR_PIN       4
#define BASE_ENABLE_PIN    7

int potPin = A0;  // Pin connected to the potentiometer (analog input)
int potValue = 0; // Variable to store the potentiometer value

void setup() {
  Serial.begin(9600);
  pinMode(BASE_STEP_PIN, OUTPUT);
  pinMode(BASE_DIR_PIN, OUTPUT);
  pinMode(BASE_DIR_PIN, OUTPUT);
  digitalWrite(BASE_ENABLE_PIN, HIGH);
}

void loop() {
  potValue = analogRead(potPin);
  Serial.print("Potentiometer Value: ");
  Serial.println(potValue);

  if(potValue < 100){
    Serial.println("----------------");
    digitalWrite(BASE_DIR_PIN , HIGH);    
    digitalWrite(BASE_STEP_PIN , HIGH);
    delay(20);
    digitalWrite(BASE_STEP_PIN , LOW);
    delay(20);
  }
  if(potValue > 800 ){
    Serial.println("+++++++++++++");
    digitalWrite(BASE_DIR_PIN , LOW);
    delay(20);
    digitalWrite(BASE_STEP_PIN , LOW);
    delay(20);
  }
  if(potValue < 800 && potValue > 100 ){ // I add this if for debbuging purpose since the motor doest stop moving
    Serial.println("000000000000000000");
    digitalWrite(BASE_STEP_PIN, LOW); //just in case, to be extra sure it doesnt activate 
    }
}

Hi, I'm trying to build an mqtt switch using an ESP32-01 as the client. The Esp32 01 runs on 3.3V solely so I tried to read up on Transistors.

Maybe a dumb decision, but in my defense I don't know a lot about transistors yet, so I asked chat gpt to recommend one for my circuit and it recommended the IRLZ44N

Now that the transistors arrived I tried to build a simple circuit esp01 gpio 0 is set as an output and will emit 3.3v (measured already and seems to work fine) that is connected to gate I tried putting a 1k resistor from the same breadboard lane to ground as a pulldown since I read the transitior can float otherwise. Drain is connected to the negative pole of a little light bulb and source is connected to both the esp01s ground as well as the 5v power supply's ground (said to do this in the data sheet of the IRLZ44N) the light bulbs plus pole is directly connected to the power supply's plus pole.

When I trigger the esps gpio 0 nothing visible happens. When I instead connect the power supply's 5v to the gate pin the lamp glows bright

Is 3.3v not sufficient to trigger the IRLZ44N?

My final goal is to use the esp01 to control a DC motor that takes 4.5v and maybe in the future other things that could take like 12v

I’m assuming it does since the documentation just mentions whatever is available on the “Serial port” but does that reference pin 11? Which is the MOSI pin on the arduino nano?

I’ve been looking for similar projects where the arduino is used as the slave peripheral but none of them actually use Serial.available nor do they really apply to my project.

I'm trying to pair my HC-05 in master mode to HC-05, that's my MAC device for it, I find it on INQ, but I can't pair it, I'm trying this manually first, connection to HC-05 and AT mode is not an issue, I get that ERROR(5) inmmediatly which I don't know exactly what means. The OBD2 is working correctly I can connect it on my phone with no issues.

I've already tried this set of commands and keep getting the same issue:

The only command not working in her is AT+PAIR which returns ERROR(5)

    sendATCommand("AT");  
    sendATCommand("AT+CMODE=0");  
    sendATCommand("AT+ROLE=1");  
    sendATCommand("AT+RESET");  
    sendATCommand("AT+CLASS=0");  
    sendATCommand("AT+IAC?");     
    sendATCommand("AT+INQM=0,5,9");  
    sendATCommand("AT+INQ");

    sendATCommand("AT+PAIR=AAC5,FF,187F58,120");
    sendATCommand("AT+BIND=AAC5,FF,187F58");
    sendATCommand("AT+LINK=AAC5,FF,187F58");
    sendATCommand("AT+RESET"); 

So I am making a sensor setup that lights follow you when you walk by for a friends work truck. He will be able to turn it on and the pir sensors notice him and the LED's light up where he is standing. My problem is how to best weatherproof my sensors without blocking the LED's. I saw some IP6K boxes but I can't find small ones any recommendations?

I’m trying to power an ESP 32 with some spare 18650 is there a chip that has USB-C on it, can charge the batteries also output a steady voltage for the ESP 32.

Hi folks. I have a single solar panel connected to an mppt and a battery, the load is a small water pump. I want to control it and set a timer with my board. I was wondering if this circuit would help.

Simple question: Is there an e ink display that works with arduino similar to those mini oled screens? Preferably SPI or I2C interface.

Hey,

So I have 2 servos powered from a separate power supply(5v 2.4A, 12Watt) to the Arduino, but with common ground, but I'm still getting really bad servo jitter. When I used the crappy servo which came in one of those "first-timer Arduino kits" when I was testing the code it was fine, but when I tried these other hobby servos I could never get them to move smoothly.

I've included the GitHub repository I've just made for this post if you can point out where I'm going wrong.

Any comments/ suggestions are appreciated. However, I don't have a wiring diagram of the setup.

Hi there,

I recently decided to build myself a little display to use with LCDSmartie, however I have this problem and I can't find a definitive answer.

When sending text from the Arduino IDE, it displays fine but when LCDSmartie is sending informations to the screen, every line is shifted and there is a "dead zone" on the bottom right that never clears up.

I am using an Arduino Uno and an LCD Display from AZ-Delivery that has been wired using this tutorial. LCDSmartie is set to use the matrix.dll library at 9600 bauds.

This is the code I used: https://pastebin.com/7hneGzKh

Hi everyone, I’m working on a basic stepper motor project using an A4988 driver and an ESP32-C3 (you can see the schematic attached). I’ve written code for stepping the motor, but when I plug the stepper motor into the A4988’s output pins (1A, 1B, 2A, 2B), the motor doesn’t move. Here’s what I’ve tried:

• Wiring: I've wired the motor correctly (double-checked with a multimeter to identify the coils). I’ve also confirmed power connections to the motor and driver.
• Code: The Arduino code is generating step pulses on pin 21 (STEP pin) and I’m toggling the DIR pin for direction. The EN pin is set to low to enable the motor. The step pulse is 50 microseconds.
• Power: The driver is powered from 3.3V logic, and motor power is supplied through VBB, so I don’t think it’s a power issue.
• Testing: I’m also using pin 8 (MIRROR_PIN) to mirror the step pulse, and this toggles correctly based on the code. Still, the motor doesn’t budge.

I suspect either the pulse timing or the driver settings might be wrong, but I can’t figure it out. Has anyone run into something similar? I’m also attaching the relevant part of my schematic and code for reference.

Any help or advice would be appreciated!

I've been struggling with getting I2S audio output working on the nRF52840 for quite some time now (months) off and on but finally got it working! The libraries showcased should support any devices that utilize the nRF52x chips. I am using some XIAO Sense 52840s in this video, which I am really liking a lot.

YouTube Video

In the end I had to create two separate libraries to make this happen, the Auto Analog Audio library + nrf_to_nrf Radio library, but am pretty proud of the results n had to share.
I just did a new release of the AAAudio lib to support I2S functionality which will be available via Arduino Library manager within 24hrs. Examples used to make the video are included with the library.

Hi I have created a code for an ebike shimano step e6100. But I'm having trouble with the electric part. I have previously connected the Stepdown to the copy of the Arduino nano but it got burn. So apparently I'm doing something wrong. If someone could help me I will really appreciate.

The code is made for the input of the sendor to go const int sensorPin = 2; const int outPin = 13;

The voltage needs to go down to 5v and the engine gives 12v The connection the engine goed though pin 13. How do I connect the stepdown? I was soldering can I used a board to connect all of it?

Hello everyone!

I’m currently working on a project using an Arduino Mega, where I have two devices connected via SPI: a BB-ADS1220 (for reading 2 strain gauges) and an LSM6DSO (accelerometer/gyroscope). I was able to connect both sensors separately and read data out of each of them with no issue. Yay! :slight_smile:

However, I’m experiencing some interference issues when trying to read them together (on the same SPI bus).

Although I can read both, when I touch the accelerometer, it seems to introduce noise + fluctuations in the readings from the strain gauge circuit (which should not read anything as it is far from the accelerometer).

Has anyone encountered similar issues when using multiple devices on the same SPI bus? Any suggestions on how to mitigate this interference? I should mentioned that I'm switching between two SPI modes in my code (SPI mode 0 for the LSM6DSO and SPI mode 1 for the ADS1220). I fear this might be the issue?

Here’s a quick overview of my setup:

• Microcontroller: Arduino Mega
• Sensors: BB-ADS1220 (strain gauge) and LSM6DSO (accelerometer)
• Level shifter: PiHut TXB0104
• Connections: Both devices are connected via SPI with appropriate wiring and grounding (see attached schematic)

Any advice or insights would be greatly appreciated!

Thanks in advance!

I Have been looking around through libraries looking for a hid library but it seems like the one from arduino is no longer working. Any help on this would be appreciated.

I just want to have the arduino run set key presses in a loop after pressing a button just in case this helps.

I am running the arduino mega also if that helps

Hi everyone! I am a former software engineer (2Y as a front-end dev) who is currently pursuing his post-graduation at a University of Applied Sciences in Germany. As with all Hochschules or Applied Science universities, there is heavy emphasis on projects and collaborative Work.

We have this subject named - Practical Studies/Industry 4.0 in our first semester and it was just announced that we have to do a project with Arduino and the group that I have been assigned to will work on Smart Farming!

Can someone please provide me some guidance on how do I get started on this as a complete beginner and no experience with IoT, embedded systems and other things.

My primary concerns are the following:

1. Knowing what all to learn and how deep to go
2. How much time would it take to learn and start building. We have only 2 months!
3. How complex or easy the project should be for a group of 4 ?
