Lesson 1 - DIOs on STG

• DIOs on STG
• stgReadDIOs() returns a 24-bit number which is
  integer of 0xPORT_C,PORT_B,PORT_A

Port D
Port B
Port A
Port C

Lesson 2 O-10v Servo Control

• http//www.epanorama.net/circuits/servo10v.html
• High resolution control from STG card

Adding a resistor between circuit output and
motor decreases signal voltage, reduces chatter

Lesson 3 Focusing Lens
Using a lens allows us to focus the incoming
signal, and get a sharper image on the detection
array, otherwise all the detectors would trigger.

• Need algorithm for controlling motors

Currently the plan is to simple compare the sides
to determine which way to steer the motors.
