Simple High Current 12V Voltage Regulator Circuit using Transistor
Voltage regulators play a crucial role in power supply circuits because they ensure the output voltage remains constant, even if the input voltage changes or the load shifts. The voltage regulator circuit we are focusing on can provide a steady 12V output with a maximum current of 3A. It can also handle situations where the […]
Transistor Based Stepper Motor Drive Circuit
Stepper motors are really popular in automation, robotics and CNC machines because they can control movements very accurately. The Transistor Based Stepper Motor Drive Circuit is a simple way to run a unipolar stepper motor using logic gates and transistors. This circuit uses four 2N2222 transistors to control the motors windings and it has two […]
Simple Temperature Based DC Fan Controller Circuit using Transistors
A simple but powerful temperature controlled DC fan controller circuit that uses transistors is really important for automatically cooling devices when they reach a certain temperature. This feature helps prevent overheating and improves efficiency. The circuit uses a thermistor to sense the temperature, which allows it to control the DC fan based on temperature changes. […]
Simple Transistor Based H-Bridge Motor Controller Circuit
A simple H-Bridge motor controller circuit that uses transistors is commonly used to control DC motors allowing them to spin both clockwise and counterclockwise. This circuit helps manage the speed and direction of the motor by using easy switching techniques. The name “H-Bridge” comes from the way the circuit looks, which is similar to the […]
