Digital Capacitance Meter Circuit Using Arduino
In this post I will show how to construct a digital capacitance meter circuit using Arduino which can measure capacitance of capacitors ranging from 1 microfarad to 4000 microfarad with […]
Arduino Tachometer Circuit for Precise Readings
A tachometer is a device that measures the RPM or angular velocity of a rotating body. It differs from speedometer and odometer as these devices deal with linear or tangential […]
Stepper Motor Driver Circuit using IC 555
In this project we are going learn how to make a simple unipolar stepper motor driver circuit using 555 timer IC. Apart from 555 timer we also need IC CD […]
How Crank Flashlights Work
A crank flashlight basically works by hand cranking a permanent magnet motor, which generates electricity for illuminating the attached LEDs. Motor Becomes a Generator Normally, a permanent magnet motor is […]
Electric Wheelchair using BLDC Motor
In this post I have explained how to make a simple electric wheelchair circuit using a standard BLDC motor driver circuit, and a couple of high power BLDC motors. Introduction […]
