Motor Workshop Example Code

This repository contains example code for driving motors via both Raspberry Pi and Arduino, as well as reading in a camera feed from a Raspberry Pi.

Raspberry Pi

The sample code available for Raspberry Pi is as follows:

• incremental.py

  • Drives a servo incrementally through its full range of motion
  • Should be run on Raspberry Pi
  • Assumes servo is being controlled over pin 25

• positions.py

  • Drives a servo motor to minimum, middle, and max positions
  • Should be run on Raspberry Pi
  • Assumes servo is rbeing controlled over pin 25

• read_local_camera_feed.py

  • Reads and displays, using OpenCV, a video feed from a local PiCamera
  • Should be run on Raspberry Pi with a monitor attached

• read_remote_camera_feed.py

  • Reads and displays, using OpenCV, a video feed being streamed over TCP
  • Should be run on an external computer, reading a camera feed streamed from a Raspberry Pi
  • Environment variables:
    • VIDEO_STREAM_ADDRESS - the IP address over which the video feed is being streamed
    • VIDEO_STREAM_PORT - the TCP port over which the video feed is being streamed

• simpledriving.py

  • Drives a DC motor at varying speeds and directions
  • Should be run on Raspberry Pi
  • Assumes DC motor being controlled over pins 5 and 12
