The advent of microcontroller modules like the Arduino opened up ability to build and program interactive objects to a whole generation of makers. Today these modules make it simple to control ...

Hardware Startup's build includes: a USB to serial converter, an ATmega328p, a 5V power circuit, and some headers. Then, you load the the Arduino bootloader on the ATmega, connect everything up ...

Here's how I build my simplified 3D printed arduino animatronic eye mechanism. This is a good option if you'd like to try out some DIY arduino robotics but don't necessarily have access to certain ...

You can hide it in something inconspicuous, and assuming you already have an Arduino and tools, it costs less than $1.50 to make. This post originally appeared on Instructables.

For under $250, you can build your own dazzler and we’ve released the source code, schematics and PCB files to make it easy. A great Arduino project for people who really like blinking LEDs.

Build yourself a little circuit to change the analog phone’s audio to regular line audio to record with your sound card. Remember that it is illegal in many places in the world to record phone ...
