What is the best way to control about 20 lamps on a pinball playfield using mbed.
What I want is simple:
1 Ball hits switch -
2 Mbed registers switch x is closed
3 Mbed tells lamp x to turn on
I've tried connecting the lamps to the digital out pins through transistors. This hasn't worked.
Too little current going into base of transistor.
I'm a bit a an mbed noob.
Help my pinball machine come to life.
Cheers
Dave
