My goal was to be able to control a Lego Powerfunctions powered vehicle remotely using my iPad/iPhone over Wi-Fi.
Initially I created a buffer for my RPi, to protect my GPIOs, using a the information from this site.
The main problem I faced, that the IR LED didn’t get enough current to successfully control a vehicle from more than 2 meters.
I got the tip to use an external powersource, which combined with an optocoupler, should be able to drive my LEDs with more current, thus giving me a greater range.
This is when my ‘real’ project started.
