  1. What version with your Stalker.

Stalker v 2.1

  1. Which capacitor button you want to setup backlight?

would like to setup so that
pressing
int buttonPin = 16; // pushbutton pin 16 (aka analog pin2)

turnes on

int BKLTPin = 17; // BKLT pin 17 (aka anlog pin3)

so that pin 17 can be a short term 5v supply from (2x2.5v 10f caps) thru "5v USB"pin

  1. Best way is use jumper wire or sold a cable from pin 3V3, that is easy for supply power to others.

I guessed the wire would be neaded :confused:
But more to the point would the caps draw too heavily on the 3.3v rail (ie shut down ATmega)
and/or should I just run a 9v battery with a voltage regulater just for the LCD?

  1. We not support about software, but you can still ask someone at forum.

I figured so but no harm in posting just in case of insight :slight_smile:

thanks
