To build this project, all you need is three main components: an Arduino Uno, a 16x2 LCD, and a push button. You can connect everything to a breadboard to keep it simple.

Probably the most complex part of working with Arduino is creating the sketch, a.k.a. writing the code. The Arduino programming language uses a variant of the C/C++ language, so if you're already ...

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 ...

But if you can push your button while your yellow LED is lit, ... Inside the cool laser-cut box is an Arduino Uno and a 9V battery, plus a current-limiting resistor and the all-important buzzer.

“So for instance, you can have one Arduino with a button, another Arduino connected wirelessly with an LED, push the button and turn on the LED without any additional single line of code to handle the ...

Like xn1ch1’s application, my push-button is connected to the Vcc rail, with a pull-down resistor to 0V. Xn1ch1’s framework stayed the same, with my adaptations limited to altering the states of three ...
