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.

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 ...

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 ...

Welcome to our blog post on interfacing the WS2811 (5V) RGB LED strip with Arduino! In this guide, we will walk you through the process of connecting and controlling WS2811 LED strips using an Arduino ...

This is just a fun Arduino project that uses leds connected in circle as a ring to produce a rotation effect. You can adjust the spinning speed with a potentiometer and you can also set a minimum and ...

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 ...

In order to recognize colors from a video input, this project employs a Python script using OpenCV. A byte of data is then sent through the serial connection between the Arduino board and the local ...

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 ...
