This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

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 ... is much more polished than that. A round circuit board holds two surface mount ICs and 12 LEDs. The whole thing looks nice fit snugly inside ...

Let it hit your red LED ... button presses would make it speed up even more. But there are really just the two speeds with the current programming. Inside the cool laser-cut box is an Arduino ...
