Make this Simple Buzzer Circuit with Transistor and Piezo
In this article I will explain how to make a very simple circuit for buzzer using piezo electric transducer, two resistors, a small coil and a BC547 transistor. A buzzer […]
Single Transistor LED Flasher Circuit
It is possibly the smallest LED flasher to date, which is able to flash an LED ON/OFF infinitely using a single transistor, a resistor, and a capacitor. Can you imagine […]
How to Connect Two or More Transistors in Parallel
Connecting transistors in parallel is a process in which the identical pinouts of two or more transistors are connected together in a circuit in order to multiply the power handling […]
