Beginner in need of help !!

Hi Henrik, thanks for explaining that it makes things a lot clearer as to how I'm going to run the code. What I would like to do is have one of the inputs (gp2), taking a reading from ADC every say 0.5 - 1 seconds.

Basically I want the chip to enter low power mode along with the device. When the device is off, one of the component pins goes to 0.00v, then when it is turned on it goes to 0.70v & stays at that. So I would like the ADC to monitor this, then when the voltage drops below 0.60v the chip is in low power mode, then when the voltage is higher than 0.60v I want it to come out of low power mode.

I hope this can be done in some way,
Rob
