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.

In this guide, you will learn how to control an RGB LED using an Arduino. An RGB (Red-Green-Blue) LED can produce a variety of colors by mixing different intensities of red, green, and blue light. You ...

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 ...

Elektor Academy Pro heeft twee nieuwe STM32-programmeercursussen toegevoegd aan de Embedded Programming Series.

Control three LEDs using three push buttons with an Arduino Uno. This project demonstrates how to control three LEDs using three push buttons with an Arduino Uno. Each button controls one LED, ...

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 ...

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 ...

This repository contains Arduino code for obstacle avoidance using an ultrasonic sensor and controlling LEDs based on the measured distance. Connect the positive leg (anode) of each LED to digital ...

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 ...
