Throttle Quadrant

Because of the high number of digital inputs, looks like I'll need a Arduino Mega 2560 for this. (Ordered 1/6/2020.) The Mega 2560 has 53 digital I/O pins.

Notes

Zero Throttle outerWhen throttle is at extreme zero (requires moving stick left past stop), connects Cannon r to Canon K (ground).
Jettison ArmIs DPDT. When closed, 1 connects to 3, and 2 connects to 4. Pin 2 is not available at Canon plug, instead, it is connected to Jettison pin 1.
JettisonWhen Jettison Arm is closed, Jettison pin 2, (Canon J) goes to level of Jettison Arm pin 4.
