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, {Read More}
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 {Read More}
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 {Read More}
In this article we are going to inestigate a simple Uninterruptible power supply (UPS) using 12V battery. We are going to explain these UPS c ircuits very simply that a new electroinics student can understand. These UPS circuits can be {Read More}
