Here you go...

You might want to take a look at;
  • R2 - Resistor value a bit high
  • Capacitor removed in climping circuit - so far it seems to work fine without
  • R1 controls brightness

It has been drawn to match the layout of the Arduino Pro mini board (That's the reason why ground is at the top). AIN0 (pin7) has to be connected right next to AIN1 - pin 6 on the arduino board.


Arduino pro mini + 8 components do the trick for now
