Arduino Mail Notifier

Arduino Mail Notifier

Many inventions/hacks often arise out of the need to solve a problem. The Arduino mailer notifier project was no exception. My workshop is in my backyard. During the day, I am far away from my mailbox. Using two Arduinos, some cheap RF modules, and a light sensor, I was able to create a solution that […]

Hacking the Wii MotionPlus to Talk to the Arduino

Hacking the Wii MotionPlus to Talk to the Arduino

The Wii MotionPlus (wm+) uses i2c (Inter-Integrated Circuits) for all of its communications. To learn how to make the Arduino talk to the wm+, we’ll program the Arduino to talk to it using the i2c protocol. This tutorial will show you how to wire the wm+ to the Arduino and toss some code into a […]
