Adafruit Protoboard for the Rasbperry Pi @ Gordons Projects. Gordon writes -

As part of my Big Trak refurbishment (not going as well as I wanted it to), I decided to use theAdafruit Prototyping Pi Plate to mount the additional electronics on.. The keypad was originally going to be the Big Traks own keypad, but I substituted one I’d made earlier (some 25 years ago!) – it’s a simple 4×4 matrix and you can see 4 resistors on the protoboard. There is a 5th next to them which acts as a limiter for the LED that’s on one of the switches.

Uses Adafruit Cobbler, Case & Protoboard.

Each Friday is PiDay here at Adafruit, be sure to check out our posts, tutorials and new Raspberry Pi related products. Have you tried the new “Adafruit Raspberry Pi Educational Linux Distro” ? It’s our tweaked distribution for teaching electronics using the Raspberry Pi.
