Arduino UNO 2. Push Button 3. LED 4. 220 ohm resistor ( for the LED ) 5. Breadboard Usually we need a resistor for the push button. However, since the Arduino UNO has a pull-up resistor built into it, ...

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.

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 ...

In this tutorial we will use two arduino one as master and other as slave. Both Arduino are attached with a LED & a push button separately. Master LED can be controlled by using slave Arduino’s push ...
