I'm trying to move on to making my own circuits outside of the arduino, and as a result I've purchased a few 168s. I use the usbtinyISP to bootload them by attaching it to the arduino (duemilanove), then I add my code and run it, and it works fine. However, when I try to build a circuit on a breadboard, I can't get the chip to do anything.
I've attached a picture of the breadboard.
pin 1 is attached to 5v high through a 10k resistor.
pin 7 is attached to Vcc (I've tried 5v and 9v, both stable)
8 is ground
i've tried 9 and 10 connected by a 16 mhz crystal and without the crystal, no luck.
pin 14 (and a few others) should turn on the attached led, but they don't.
pin 20 is attached to Vcc/pin 7
pin 22 is attached to ground/pin8
thats it. the only thing that happens is sometimes the lower end (pin 14-15 end) gets hot. Please, tell me what I'm doing wrong here.
Thanks for your help, in advance.http://www.uploadgeek.com/thumb-4982_49E8E1AC.jpg
I just realized how small the pic was resized to. Sorry if you cant see
