Raspberry Pi: Using GPIO Inputs
This video explains how to connect physical switches, reed switches and an Adafruit IR reflectance sensor to a Raspberry Pi and to communicate with them using Python. You can discuss this video on YouTube. The Python scripts (code) used in the video can be viewed and downloaded from the following links: The breadboard circuit diagrams included in the video are reproduced below. Note that the IR reflectance sensor can be obtained from Adafruit in the USA here, or from Pimoroni in the UK here.    Return to: Videos Homepage.
