“Sensors make working with any project fun and simple to do, there exist thousands of sensors and we get the choice to choose the right sensor for our projects or needs. But nothing is better than designing your own DIY sensors to work with a wide range of micro-controllers so you have the exact design you need for your project.
This instructable will be a part of a series of Instructables in which I show you how to build sensors compatible with the most microcontroller you can find. In the last two Instructables, I showed you how to how to make a Tilt sensor, Vibration sensor and how to make a Touch sensor. In this instructable, I’m going to show you How to design your own light sensor, which could be used as a day and night switch or as a part of a security system.”
