Introduction: Raspberry Pi Big Trak Jr

A robot I coded using a Big Trak Jr, A Raspberry Pi and a HBridge chip.

Works by receiving data using a node server running on the pi from my computer or laptop which run a client linking to the server with now.js, then this data is run through node and then wrote to the GPIO pins either 0 or 1.

I made the code by using Nano via SSH on the Raspberry Pi to prototype it and the client code on my own VPS.

During this I learnt basic socket communication using Node.js and GPIO on the Raspberry Pi

I have one of these sat on my desk with my son begging me to mod it.
Do you have a schematic for the motor driver?
