Raspberry Pi: Using GPIO Inputs

Описание

How to connect physical switches, reed switches and an Adafruit IR reflectance sensor to any Raspberry Pi and communicate with them using Python. I also explain in depth the concept of pull-up and pull-down resistors.

You can access all of the code and circuit diagrams featured in this video here: http://www.explainingcomputers.com/pi_gpio_inputs_video.html

The Adafruit IR reflectance sensor can be obtained from Adafruit in the USA here: https://www.adafruit.com/product/2349 -- or from Pimoroni in the UK here: https://shop.pimoroni.com/products/reflective-ir-sensor-with-470-and-10k-resistors
