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.

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 ...

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 ...

I would like to try running things using an ESP32-based board with Arduino. When it comes to running microcontrollers, the classic starting point is the "blink"—making an LED flash on and off—which is ...

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 ...

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 ...

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 ...
