Normally, we use a Joule Thief circuit to illuminate an LED higher than 3V, from a 1.5V AAA Cell, which looks outstanding and very useful. However suppose you don’t have a 1.5V Cell, instead you have an access to a small 3V DC PM motor, then could you use this motor as a DC source […]

Automatic Ultrasonic Water Pump Motor Controller Circuit
This project explains how to build a fully automatic ultrasonic water level controller where the water pump motor starts automatically when the tank level goes below a preset LOW level and stops automatically when the tank becomes FULL. The whole system is wireless, reliable, and there are no corrosion problems because the ultrasonic sensor never […]
A4988 Motor Driver Circuit Diagram with IC 555
In this article we now talk about a very simple but very useful stepper motor controller that uses one A4988 driver module and one 555 astable pulse generator. Overview Of The Circuit So we first see the main building blocks. We have one A4988 module that drives any small 2 phase stepper motor. We also […]
Servo Motor Working Explained
We know that servo motors already exist for very long time and we also see that many people use them in many applications. These motors look small but they give big power and also they save lot of energy. So now many people who like electronic things and who want to understand more about such […]
Pump Motor Timer Circuit Diagram with Dry Run Protection
In this post I have explained about a circuit which can be used to monitor and detect the presence of municipal water supply by operating a pump motor through an intermittent ON/OFF timer. The timer keeps the pump motor ON for 15 seconds, if water is not detected, the pump is switched OFF for the […]
High Voltage DC Motor Speed Regulator Circuit
In the realm of motor control systems, high voltage DC motors play a crucial role in numerous industrial and automotive applications. Efficiently controlling the speed of these motors while ensuring operator safety and isolating sensitive components can be a challenging task. However, with the advent of advanced technologies, such as optocoupler motor controller power stages, […]
