Entries in cat (4)
This is a simple bot that really belongs installed in an R2-D2 toy. It's simply an Ardweeny on a breadboard, a set of AA batteries, a continuous rotation servo, a standard servo, and a laser. If there's a desire for source code, I'll post it here. However, it's simply a matter of random writes to both servos (after calibrating the vertical servo so it doesn't move more than 15 degrees.)
For Adafruit/Instructables "Make it Tweet" challenge, I assembled a way for an Arduino microcontroller to monitor and post updates to Twitter when the cats eat, need food, and need water. Here's an overview video:
The complete project is posted on instructables, complete with source code and schematics.
