-Optionally, GPIO 17 can be used to drive an NPN-transistor (BC337-40) that pulls a p-channel MOSFET (IRF9520) to GND in order to switch off current. Transistor-current is described [here](https://dl6gl.de/schalten-mit-transistoren): Just have a look at Abb. 4. R1: 10k, R2: omitted(!), R4: 10k, R5: 4,7k

 ### Modification RFID-tags
-There are special RFID-tags available, that don't start music by themself but can modify things. If applied a second time, the corresponding acting will be reversed.
