I'm trying to do a detailed breakdown of ALL ATmega328 Transistor Tester Options from the minimum system to the full bells and whistles version. Does the following list look correct so far?
Absolute Minimum System1.) 3× 680R resistors matched within 0.1%
2.) 3× 470k resistors matched within 0.1%
3.) 2× 100nF Capacitors (AVCC & AREF to GND)
4.) 1× 10k Resistor (Reset Pin)
5.) ATmega8/88/168/328
6.) Your Choice of LCD + Supporting HW
7.) 0.1% scientific laboratory grade power supply w/5.000 volt output
8.) Push Button

The idea is to subdivide every extra circuit option on a schematic... you will see
With this level of breakdown I should be able to explain everything from the 328 version visually without language. Basically I'm creating an ikea instructions type version of the pdf.
