Simple Transistor Relay Driver Circuit

Last updated on 3 June 2025 by Admin-Lavi Leave a Comment

Small switches called transistors are found in almost every electronic device. However they are unable to manage an abundance of power alone. A transistor relay driver is similar to a specialized transistor adapter. It enables the control of a strong relay switch by a tiny transistor signal. This makes it possible to turn ON and […]

Simple Voltage Regulator Circuit using Transistor and Zener

Last updated on 3 June 2025 by Admin-Lavi Leave a Comment

This circuit is like a bouncer for electricity. It uses a transistor like a gatekeeper and a special Zener diode to make sure the voltage stays steady. The Zener diode is like a set point and the transistor copies that voltage keeping it constant for ones electronic devices. This is a great project where ups […]
