Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...
A teacher I know is stuck, with only npn transistors in the supply cupboard and the need to create a reversible motor drive for an Arduino project. Reversing ‘bridges’ have four switches (relay ...
In this article we will discuss how to build a powerful DC motor driver that can be controlled using a microcontroller like an Arduino or a Raspberry Pi, or even a standalone PWM generator chip. DC ...
