Comparator and how to use it (explained with real life application) - Electronics Basic #1

In this video I talk about basic electronics. I'ts comparator, a component that very useful in everyday electronics. If you think I should do more on basic electronics video. Let me know by leave your comment here.

There are three basic comparators.
1. Non Inverting Comparator
Non Inverting comparator wil output HIGH when Voltage Input more than Voltage Reference

2. Inverting Comparator
Inverting comparator wil output HIGH when Voltage Input less than Voltage Reference and output LOW when Voltage input more than Voltage Reference

3. Window Comparator
Window Comparator will create certain voltage threshold. Will Output HIGH when Voltage input more than Lower Voltage reference but will Ouput LOW once the Voltage input more than Upper Voltage Reference

In this video we also practice the theory by make an auto on off switch based on temperature.
