A stepper motor is a motor that moves in steps. Well, DUH! Isn’t that obvious? But it may not be. Because the notion of moving in steps is not as trivial as we may think. In fact, the ability to…

Yet another DC Motor Controller

I don’t know why, but a few weeks ago I felt like improving my AE-DC1 DC motor controller. At least the results were pleasing. The AE-DualDC3A module is considerably easier to use than its predecessor. It is just a little bit…

Cobotrox I in Action

Like I explained on my previous post, I was finally able to take my old electric wheel chair platform and remote control it by using a very simple decoder that takes RC PWM signals and generates DC Motor PWM signals.…

Understanding PWM

PWM stands for Pulse Width Modulation and it basically means precisely that. You have a pulse, and if you can change the width of the pulse without changing the frequency, then you have modulated its width. Lets first take a…

DC Motor Control Basics

You have a DC Motor you want to control it. But how? And what does DC Motor control means? Pretty much when we are talking about DC motor control, there are 4 aspects we need to get our minds busy with:…

Removing the Brakes

Wheel chairs are meant to carry somebody, usually somebody that can not walk. It should be of no surprise that in the last few decades, architectural constructions have been mandated to take this into account.  Wherever you go, there are…
