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 tutorial, we will learn how to control the MAX7219 Led Matrix using Arduino by displaying a simple text. LED Matrix. We will use the FC-16 module which has four cascaded 8×8 LED matrix ...

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

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 ...

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 ...

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 ...

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 ...

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 ...
