I compiled the code with eclipse avr and used usbtinyisp with no problems whatsoever. I used your example for 1 of my 1st avr projects. thanks tim Nice work Alex!

But I figured that the problem is the ADC; it is not working due to different instructions for the tiny13 and tiny45 to get the ADC running. Since I'm a very poor programmer, but more of an "electronist" I have to put some effort in making " ADMUX = (1 << REFS0) | ADC2; " equivalent to the tiny45. This may take some time due to my programing handicap :) Merry Christmas to you all!

I haven't tested blue LEDs, but I think they will not work properly, because they need about 3-3.2V and the coin cell is only 3V and there is a voltage drop along the microcontroller outputs. Cheers, Alex Hi Peter,

Also, can I use Blue LEDs?

Telling "Be patient." while soldering cannot be done often enough. ;) I think I didn't get it as beautiful as your one, but it's nice. I really like this idea. Greetings from Aachen.

The ADC is setup to use the internal reference (1.1V). So if PB4 gets somehow voltages above 1.1V it will report 1023. How do you power your setup? Another option for debugging is: use an Arduino to measure the voltage across the LED. You can even measure the voltage with a multimeter. And I'm not sure if the code works on a tiny45 without any adoption. HTH. Cheers, Alex Hi Sebastian,

But I can't still figure out why it is not working :( Acctually it breaks just between 1023 and 1024 (surprise surprise!) But I can’t still figure out why it is not working :(

I built it with tiny45, but have some issues (it does not work :D ). The problem I think is the light sensing part or maybe some forever sleeping watchdog. When I change the AMBIENT_LIGHT to something high (like above 1000) it lights up from the beginning, but does not stop, even if i use very bright light. If I go below 1000 it does not light at all, even if I put it in a dark room. Someone have a guess on whats wrong? I like this project very much!
