I'm going to use a ATtiny 13 to PWM a led display. I've never playedwith a AVR tiny13, it should be simple.I notice that it has an ADC on it, and would like to use this to sensethe ambient light, and increase the LED on time accordingly. It's not for scientific type stuff, so it doesn't need to beexceptionally linearAny recommendation for a sensor, cheap, but not Joerg cheap, andsimple to mount, not the bumpy thingsmartin

What the ADC impedance? You could try a led, they do produce a small voltageunder ambient light.Cheers

Daylight sensors recommendation?

LED matrix the off times can be awfully brief.

it back. Not a problem if the ADC has a good

inline-assembler.

If he's using a 7-segment, he could use one of the free decimal points...

Just a thought.

Good idea, as long Martin (the other Martin) can find a vacant IO port that can be muxed to the ADC.
