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 ...

This project illustrates how to control an LED with a push button connected to an Arduino board. Pressing the button will toggle the LED on and off, making it an excellent introductory project for ...

The IR sensor's pins are attached to Arduino as so: (from left to right with the sensor's head facing you) (Vout) Pin 1 to pin 11(Arduino) (GND) Pin 2 to GND(Arduino) (Vcc) Pin 3 to 5v(Arduino) Now ...

The Button will send “N” letter to HM-10 which will turn on the LED connected to Arduino. Similarly create a button for LED OFF and give it a Red Color. . The Button will send “F” letter to HM-10 ...

On the other hand, the Arduino IDE only lets you program Arduino boards with the Arduino programming language, which is based on C++. With that over, let’s make the Arduino blink its internal LED!

To make things a little easier to see, you can try connecting an LED bulb and a 250Ω resistor between D13 and GND. Do this on a breadboard to make it easier and make sure to disconnect the Arduino ...
