Step 4The CPU & Crystal
I didn't bother to make a circuit board for this project, it's easier to just solder it all together in dead bug style. (Actually I would rather call this a squashed bug because the chip is not turned upside down, but it's flattened out/squashed... ;-)
Begin by flashing the software into the chip (ATtiny2313) and test it to make sure that it works.
Then flatten the chip by angling all the leads outwards.
Solder the crystal to pin 4 & 5 on the chip. I ran the leads of the crystal on the bottom of the chip to get them out of my way.
Solder the 20 Kohm resistor between pin 1 (reset) and pin 20 (plus).
Solder the two 20 pF capactitors to pin 4 & 5 and then solder them both to pin 10 (minus).
Solder the 100 nF capacitor between pin 10 (minus) and pin 20 (plus).
