The button states could easily be read by using an Arduino’s analog input. A Pro Mini model was chosen for its small size as it could be housed in the radio compartment of the dash.

When the Arduino code sees the button getting pressed, it brings the corresponding LED pin high and starts a fade out timer using the SoftPWM library by [Brett Hagman].

DIY musical instruments are their own thing entirely, but if you're looking for a place to start, Adafruit has a guide to building your own MIDI controller using an Arduino.

Premier space exploration disaster simulator, Kerbal Space Program, is fun to play with regular controls, but it can be improved with this DIY build that lets you launch ships with a giant red button.

Using motion detectors and an Arduino you can trigger lights, fans, or even an pneumatically controlled cleaver-wielding clown to help add your house to the “if you dare” list.

This year at CES, Intel introduced Curie — a button-sized system-on-chip module made for low-power wearables — but the company was mum on what would be the first products to use it. Now we ...

Arduino Defined Arduino is described by its makers as “ an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software,” whatever that means.

Nearly every home-built project we cover uses Arduino somewhere, and the open-source microcontroller system is now out of the beta stage, having reached the version 1.0 milestone.

If, however, they don't seem to be a great fit for your needs, there are several other small Arduino boards you can use instead, including the Micro (18 by 48 mm), MKR Zero (25 x 61.5 mm) and MKR ...
