Almost everything is the same, but we don't have to build a transmitter.
- Now be careful: we have a NeuroSky brainwave measuring tool that is the transmitter. This is working with Bluetooth. At the "Connecting the Communication Modules" part program your HC-05 module to connect to the address of the NeuroSky headset. And there you go... It is a litle bit tricky, but the video shows you everything.
- The brainwave controlled version isn't as precise as the other so I decided that I add an ultrasonic distance sensor module. This way I can avoid obstacles.
