LESSON 6: Photoresistors & Thermistors

April 12 @ April 12 - April 12

Photoresistors are light-dependent resistors whose resistance changes depending on the amount of light hitting the sensor. This makes them perfect for light-controlled switches and projects. When paired with a relay (which we’ll cover in a later lesson) they can be used to turn on a light bulb when it gets dark, track daylight in a weather station, and much more. Similar to photoresistors, thermistors change resistance depending on the temperature. You can build projects that perform an action like lighting an LED or sounding an alarm when the temperature goes above a certain point or even turn on other components like fans and motors. They’re ideal for equipment control and protection circuits.


MATERIALS:

You’ll be able to follow along and build all the projects featured in this course with the ELEGOO UNO Project Super Starter Kit.
