Home Security System Project Using Laser and LDR
This is a home security system project that uses laser light and a light sensor (LDR). A security system is used to protect our homes, offices, banks, lockers, etc., from unauthorized persons. There are different types of security systems available, and a laser-based security system is also an important and efficient type of laser light … Read more
Buck Converter Circuit Diagram, Working and Applications
In this short post, we are going to explain the buck converter circuit. A buck converter is a type of DC-DC power converter that steps down a higher DC voltage to a lower DC voltage. It is commonly used in power supplies, LED drivers, battery chargers, and many electronic devices where efficient voltage regulation is needed. … Read more
Change the Direction of a DC Motor
This circuit is about how to change the direction of a DC motor using a BC547 transistor. Since the BC547 transistor is a small-signal NPN transistor, it cannot directly drive most motors. So we usually combine it with a relay or use it to control another high-current driver. In this circuit we are going to use … Read more
