In this Raspberry Pi light sensor tutorial I show you how to correctly connect the photo resistor sensor up to the GPIO pins. Lastly I show you how it can be used in a simple python script so you’re able to gather and use the data from it.
This is yet another sensor that I will be looking at incorporating into future projects such as a light activated alarm clock.
I explain a bit further down each of the parts that I will be using in this circuit. Be sure to read up on it if you need more information on these. It is important to note for this tutorial I am just using a simple photocell sensor whilst these are perfect for some tasks they might not be as accurate as you would like.
