Once powered and programmed, the three push buttons will control the three LEDs as follows: Pressing Button 1 turns on LED 1. Pressing Button 2 turns on LED 2. Pressing Button 3 turns on LED 3.

This project is built using PlatformIO. The code is structured to separate hardware interactions from the core logic, making it testable without actual Arduino hardware ...

Did you know that you can use Arduino to turn on an LED when you press a button? Well, it is true, you can do this! Leaving the joke aside, let me show how you can achieve this. You will need the ...

Uploading the Arduino LED Blink Code. Now, let’s upload our first program to the Arduino board through the Arduino IDE that we just downloaded. The Arduino IDE when installed comes with some example ...

The wiring for this project is about as easy as you’d expect: the buttons connect to the digital inputs on the Arduino, and the LEDs on the digital outputs. When the Arduino code sees the button ...

Here is a simple Arduino Camping Light project. In this design, only one push button switch is used to control the light output (from a bunch of white LEDs) between off, dim, medium, and full ...

We previously used multiplexing technique in Arduino to interface 4-digit 7-segment display and driving 8x8 LED matrix. Charlieplexing allows you to control N * (N – 1) LEDs, where N is the no of pins ...

[Christian] wrote in to tell us about his third-generation Arduino MIDI sequencer (translated) called the AM808 VX3. He had already laid a strong base for the project in his previous versions. But … ...
