Simple. Positive side of V goes to Analog In.

Buttons include: UP, DN, LT, RT, A, B;

This circuit has many many use applications. Configuration can be rearraged for D-Pad with two action buttons. The voltage spread is relatively even between 125mV-2.25V. This will prove useful during coding, as resistor values are subject to change with temperature and supply votage. The difference between
