Simple 555 Timer Based Transistor Tester Circuit
Transistors are really important parts of electronic devices. They help make signals stronger, switch things on and off and do a lot of other tasks. To make sure they are working properly it is important to test them. This helps fix problems in circuits and find any broken parts. In this article, we will look […]
Building an Auto Street Light Circuit using IC 741 and Transistor
Building an Auto Street Light Circuit using IC 741 and Transistor, which turns street lights on at night and off during the day, is a simple but efficient way to save energy. This design employs a relay to operate the street light, an LDR (Light Dependent Resistor) for light detection, BC547 transistor used to drive […]
Simple Transistor-Based Voltage Booster Circuit
The requirement for greater voltage levels from low-voltage power sources is a frequent problem in current electronic applications. Devices can function properly even with low power supplies thanks to a voltage booster circuit, which raises the voltage. With the help of a PNP transistor 2N2907, an NPN transistor 2N2222, and a variety of passive parts […]
