Simple Charger Breakdown Alarm Circuit
In electronic system good charger circuit is very important, as it give power to things like battery. Also, this Simple Charger Breakdown Alarm Circuit check charger is working or not and if problem found then buzzer makes sound. So user know fast if charger fails and this stop battery from drain or damage, also it […]
Simple Short Circuit Detection and Alert System
Simple Short Circuit Detection and Alert System is very important in power system, as it stop damage when short circuit happen. Short happen when positive and negative wire get touch and this make big current flow and can break parts or burn wire. Furthermore, circuit uses 2 transistor, buzzer and LED to find and show […]
Simple 555 Timer Based Transistor Tester Circuit
Transistors are very important in electronics and they make signals strong and turn things ON/OFF and do many jobs, hence, to check if its good then we need to test them. Also, testing helps find problems and broken parts. This article for Simple 555 Timer Based Transistor Tester Circuit which show easy way to test […]
Building an Auto Street Light Circuit using IC 741 and Transistor
This post talks about Building an Auto Street Light Circuit using IC 741 and Transistor, as it turns ON at night and OFF at day. Furthermore, this circuit is simple and saves energy and it uses relay to control light, LDR to sense light, BC547 transistor drives relay and IC 741 works as a comparator. […]
Simple Transistor-Based Voltage Booster Circuit
In many electronics low voltage is not enough but need only higher voltage, so this voltage booster circuit helps, take low voltage and makes it higher. Also, this project for Simple Transistor-Based Voltage Booster Circuit show how to make voltage booster using simple parts like: PNP transistor 2N2907, NPN transistor 2N2222, resistors, capacitor, diode, inductor.
