  - 1 x 12Vdc Power supply for motors
  - 1 x 5Vdc Power supply for Pi

## Prerequisites - Software
  - Raspbian
  - Python3
  - Adafruit CircuitPython MotorKit https://github.com/adafruit/Adafruit_CircuitPython_MotorKit
  - Hamlib https://github.com/Hamlib/Hamlib/wiki

## Optional - Software

  - Install Raspbian and the other prerequisites
  - Download files from github Pi-Rotate and stepper directories
  - Test motor operation with program stepper.py
  
## Operation
  - In a terminal, start program Pi-Rotate.py   make note of the pseudo terminal name, probably: /dev/pts/0
  - In another terminal, start program rotctld: rotctld -m 202 -r /dev/pts/0     (the last argument must match terminal name above)
  - In another terminal, start program rotctl: 	rotctl -m 2
    - use the P az el command to point the antenna North and level
    - use the R x command to reset the az & el
    - quit
  - start gpredict
    - verify time & direction of upcoming pass
    - open Antenna Control window; choose satellite; Tolerance 0.2 deg; Engage; Track
