The Arduino Uno LED Push Button Key Switch Module integrates a push-button switch and an LED indicator into one component. When the button is pressed, it activates the switch and illuminates the LED.

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 ...

When you read “Arduino wristwatch”, you fall into the trap of envisioning an Arduino UNO clumsily strapped to someone’s wrist. [Marijo Blažević’s] creation is much more poli… ...

I made this Arduino 8 bit binary led counter as a solution for one member from Arduino forum. He asked if somebody can make a project that displays a decimal number in 8 bit binary format using 8 leds ...

But there are really just the two speeds with the current programming. Inside the cool laser-cut box is an Arduino Uno and a 9V battery, plus a current-limiting resistor and the all-important buzzer.
