While making my mini table saw I bought a 12 V motor speed controller module from eBay. Fair enough, I thought … that was an easier and straight forward solution. But then I decided to make my own. I did some hunting around on the interweb and found a pretty good starting point in Circuits

In part 1 of this series, we looked at the basic commands for using software pulse-width modulation (PWM) in RPi.GPIO 0.5.2a and higher. In this article we’ll get a bit more hands-on and into some practical applications for it. It’s all very well being able to make nice square-wave pulses on an oscilloscope, but what’s

Vendor’s Description:Â Finally I got my first test with HatalĂłgico and it looks promising: just out of the box PWM working. That means servos working right in the same platform as a powerful linux board! If you don’t know the HatalĂłgico board for Raspberry Pi, go and check it here, there are 3 days left

After my dad and I got an LED to dim using Pulse Width Modulation on my Raspberry Pi, we decided to try to spin a servo motor.  We had a bunch of old servo motors on my robotics team at school so I used one of those, but I didn’t have any information on the

Dimmer With MOSFET This circuit shows that dimmers intended for use at mains voltage do not always have to contain a triac. Here, a MOSFET (BUZ41A, 500 V/4.5A) in a diode bridge is used to control the voltage across an incandescent bulb with pulse-width modulation (PWM). The power supply voltage for driving the gate is
