I can’t upload my code to my uno. I already restart my board, update the module, reinstall the IDE and there is no input on the Tx/Rx pins. I try to upload an empty file that only have void loop and void setup also failed. An error occurred while uploading the sketch C:UsersHPAppDataLocalArduino15packagesarduinotoolsavrdude.3.0-arduino17/bin/avrdude -CC:UsersHPAppDataLocalArduino15packagesarduinotoolsavrdude.3.0-arduino17/etc/avrdude.conf -v ..

I’m having issues with Arduino and RPI3 serial communication, it’ll become unresponsive after a little time. RPI3 python code import serial import time if __name__ == ‘__main__’: ser = serial.Serial(‘/dev/ttyACM0’, 9600, timeout=1, writeTimeout=0) ser.flush() last = "onn" while True: last = "onn" if last == "offn" else "offn" ser.write(last.encode()) print(last) time.sleep(0.5) Arduino code const int ..
I’m working with an Arduino Uno and WS2812b LED stripes. What I’m trying to do: So I’ve a 12 x 10 grid of LEDs and I’ve made a software that maps these LEDs to a texture of the same size, which I can draw to. I now want to make multiple textures and send them ..
Why am I having extra character printed in serial port? See the attached screenshot, please. Extra character in my Nextion command see circled area There is 0x1A received and I am not sending carriage return. I developed a code to implement communication between nextion display and ATmega328P over serial port. The issue at hand, in ..
I came to this forum because I have a question about my project. I have to make a memory game for school and this has worked out quite well. But now also want to add time. The maximum time a user has to push a sequence. When this time has elapsed –> GAME OVER. I’ve ..
Components: Arduino UNO ultrasonic sensor hc-sr04 LCD display Active buzzer Project: Parking car sensors that calculate the distance between the car and the object and start a buzzer sound when it’s x distance away from it. This sound speed should increase with the decrease of the distance and that what I am facing a problem ..
I am trying to split an array into 4 different elements, however when I implement the math into the code, it spews out random numbers… Source: Windows Que..
I ordered a sensor that measures three parameters at specific register addresses. The sensor uses a modbus protocol for communication (RS 485). I use the arduino as master and the sensor as slave. Since I don’t have the sensor yet, there is a software (Modsim32) running on my windows 10 computer that allows me to ..
I was following this tutorial: https://www.instructables.com/DIY-Larson-Scanner/ Upon loading the code, I received error’s for some of the initializations. I changed them and moved some pins around on my Arduino UNO r3, then I was able to get a lighting sequence from the first LED to the last LED. The problem I am having is that ..
I have an arduino and I am trying to run the following code. I am using the stepper model "28BYJ-48". It uses a driver board and I cant seem to find out how to run this. The code wont run and I have tried to re wire and see tutorials. It there any code which ..
