Inside is Arduino Pro Micro and a PMW 3389 optical sensor on a breakout board. [Ben] was going to use flexible 3D printed panels as mouse buttons, but then had an epiphany — why not use keyboard ...

This typically includes resistors, push buttons, and sensors, as well as jumper wires and solderless breadboards. You can buy these items separately from shops like Adafruit and SparkFun , but ...

If you are just learning how to do Arduino projects or want to start, ... with only an Arduino UNO, ultrasonic sensor, force-sensitive resistor (or push button), ...

[Lars] shows you how to get a perfect score on the first four levels of BIT.TRIP RUNNER by using an Arduino to time and send button presses. This is a pretty simple game that uses a couple of butto… ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

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 ...
