Building A Laser Trip Wire at PyroEDU

In today’s PyroEDU lesson we continue with our new course: An Introduction To Sensors and take a look at how to sense light. Light Sensors like the photoresistor and photocell are very important and use throughout society. In this lesson we will go through the theory about photoresistors and perform a fun experiment to give you a hands-on feel for how they work. Here’s a quick intro of what this PyroEDU lesson is all about:

Light is an element that is crucial for life on earth and it is also something we can easily sense electronically. In this lesson we will use a photoresistor to detect changes in brightness by making a laser trip-line.
