3 Best Transformerless Inverter Circuits
As the name suggests, an inverter circuit that converts a DC input into AC without depending on an inductor or a transformer is called a transformerless inverter. Since an inductor […]
4 Simple Proximity Sensor Circuits – Using IC LM358, IC LM567, IC 555
Video Demonstration An IR proximity sensor is a device which detects the presence of an object or a human when it is within a predetermined range from the sensor, through […]
L293 Quad Half-H Driver IC Pinout, Datasheet, Application Circuit
In this post we investigate the technical specifications and pinout details of the IC L293 which is a versatile quad half-H driver IC, and can be used for implementing many […]
Triac Phase Control using PWM Time Proportional
A triac phase control using a PWM circuit can be useful only if it’s implemented using a time-proportional format, otherwise the response could be haphazard and inefficient. In a few […]
Single Phase Jet Pump Controller Circuit
The post explains a simple single phase jet water pump controller circuit using magnetic reed switch level sensor, and a set/reset circuit. The idea was requested by Mr. Nanigopal mahata […]
