Sleep Timer
Quote:You use sleep_mode inside the ISR, I've never seen that. I think it's impossible. No problem to sleep inside an ISR. I.e I have an application which throw an INTx ISR if...

How to sleep AVR from within an interrupt handler?
This ISR works for me to go sleeping if power is lost. INT1 sense if power pre regulators is lost and MCU goes to sleep inside INT1 ISR, to periodically wake up by TCNT2 Overflow...

Digital Resistor, built like a R2R DAC?
You could also use a photo-cell, AKA LightDependantResistor (LDR). Let the micro control a LED using PWM. The LED shine on the LDR and the more light the less resistance. Very...
