On Semiconductor – I think they are mainly a distributer of ICs, not a manufacturer. Others were snagged from web sites wherever we could find them.

Course topics EE Lx Lab Notes – A collection of topics related to constructing the class projects soldering, wire wrapping, debugging, etc. Implements a 3-bit up-down binary counter with binary outputs and seven-segment display outputs.

This document discusses programming the ATmegaP but much of the information also applies to other ATmega or ATtiny microcontrollers used in the class. Their inventory changes a lot so you might not be able to buy the same things six months from now.

The notes below mostly apply to both microcontrollers even if the description of the document only mentions one of them. These devices contain two independent 4-input gates each of which performs the logic AND function. Many of their files are scans of pages from their printed databooks and the images come out looking pretty bad. S – Controls an LED with a switch. All students should read this before starting construction of your project in the lab.
