Step 18 - Short Expansion Port Headers:

get lost. Install them on the

spots.
These headers are special in that they’re short, specially selected to mate with
short-pins on the expansion breadboard.

Step 19 - Install Atmel ATMega8L
- This is a static-sensitive part, so if you
frequently “zap” people, you’ll have to be careful. Do this near a sink, and touch
the metal faucet just before doing this, as it will remove any static charge.
Insert the Atmel microcontroller. Note that the notch on the end of the chip
must match the notch on the PCB, which is on the left side.
As the chip has legs that splay out a bit, you might want to bend the legs inward
so it fits into the chip carrier easier.

Gently bend all the chip
pins inwards.
