This project demonstrates how to control an LED using a push button with an Arduino board. When the button is pressed, the LED toggles on and off. This simple circuit can be a great starting point for ...

This project enables individual control of an array of 8 LEDs using an Arduino Uno. Each LED is connected to a separate digital pin on the Arduino, allowing for versatile light patterns and displays.

Similarly create a button for LED OFF and give it a Red Color. . The Button will send “F” letter to HM-10 which will turn off the LED connected to Arduino. Now you can see the two buttons created just ...

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 ...

Then Arduino commands the IR LED to blink in a particular pattern, corresponding to the button pressed on that Android Device App. This blinking pattern is captured by TV or Set-Top box’s IR receiver ...
