More shopping

Whilst I wait on the Secret Motor Drivers, I decided to snap up another little bargain, one of SparkFun's 20x4 LCD screens (pictured).

This LCD should be perfect for displaying information from the camera, allowing testing and debugging without using the serial interface (a problem if that interface is shared with your serial CMUcam as all data sent "to" the arduino serial monitor is also sent "to" the camera, which then returns a cacophony of errors.

Also, this will allow real-time data display whilst the robot is moving, without having it tethered via USB.

Finally, I made it onto Make Blog via my submission to Let's Make Robots!
