This circuit uses an Arduino UNO to control an LED and display its status and a switch status on an HD44780 LCD. 1.LED: LED: Connect the anode to pin 13 through a 220Ω resistor and the cathode to GND.

I would like to try running things using an ESP32-based board with Arduino. When it comes to running microcontrollers, the ...

While working with the RGB LED, I had to pay attention to the LED pin configuration, resistor connections, Arduino pin numbers, and breadboard connections. Checking each connection helped me ...

This project demonstrates how to connect and control an external LED using an Arduino Uno. It’s a simple and fundamental project that introduces the basics of digital output. In this project, an ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

Regular candles can be awfully boring at times. They can only produce one color and the flicker is so… predictable. They can’t even be controlled by an infrared remote control, not to mention the ...

Sure, the physical build itself looks great, but it’s what [Michael] did with the firmware that impresses us the most. He’s using an Arduino Mega to drive the 7x7x7 cube and manages to squeeze out ...

A Python module for controlling Arduino devices with LED control firmware. This package includes the compiled Arduino sketch and Python code for easy communication with Arduino boards.
