atmega328 - where to buy
I've ordered lots of bits from tuxgraphics in the past and it's always been hassle free. I've also emailed Guido from that site questions in the past, and he's clearly an AVR...

atmega328 - where to buy
This place is also excellent and has them in PDIP with very cheap shipping around Europe (about 3 EUR to the UK): http://shop.tuxgraphics.org/elec...

5v input to ATmega88 at 3v3
emuler - I wired up the USART and added some debug, and the pin isn't seen as changing, so there is no problem with timing - something worse than that :( kevin123 - I've removed...

5v input to ATmega88 at 3v3
Hi, The pull up is definitely disabled, and the pin is a little under 3.3v when the IR receiver is seeing nothing (it's active low, so normally outputs 5v). I was wondering if...

Printing ADC value to terminal
You need to convert the binary value into a string. sprintf() can do this for you: void WriteNum(uint8_t val) { char buf[4] uint8_t t = 0; sprintf(buf, "%3u", val);...

Wiring input switch to ATmega88 with internal pull-ups
Brilliant! I failed to consider misconfiguration of the pin - thank you for pointing this out! I'll add a series resistor as you say. Many Thanks, Mike

Wiring input switch to ATmega88 with internal pull-ups
I'm happy using the pull-ups. More I'm wondering if grounding the input without another resistor is entirely safe. Since you didn't mention this, I'm starting to suspect there...
