Raspberry Pi PWM Tutorial

Raspberry Pi is an ARM architecture processor based board designed for electronic engineers and hobbyists. The PI is one of most trusted project development platforms out there now. With higher processor speed and 1 GB RAM, the PI can be used for many high profile projects like Image processing and Internet of Things.       [caption id="attachment_10501" align="aligncenter" width="615"] Raspb ...

PWMcontrol on Raspberry Pi: installation and first test on Hatalógico board

Vendor's Description:  Finally I got my first test with Hatalógico 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 Hatalógico board for Raspberry Pi, go and check it here, there are 3 days left to get it at a special price and features. So these here are my steps to get the Hatalógico working. I'm ...

Safe and simple AC PWM Dimmer for arduino / Raspberry pi

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 supplied by the voltage across the MOSFET. add on board:raspberry pi diy add-on board  S ...

RaspberryPi Pulse Width Modulation Demonstration

This instructable is a demonstration of the settings used to control the hardware Pulse Width Modulation (PWM) on a RaspberryPi. If you are just fading an LED the default settings are good enough, but if you are trying to control a servo, a stepping motor, or anything critical you will want to change some of the settings. You will need: 1 - A RaspberryPi 2 - Speakers plugged into the speaker jack (Not HDMI) ...

Controlling a servo using Raspberry Pi and WiringPi software based PWM

Controlling a servo using raspberry pi PWM generator is not a trivial task since PWM period cannot be defined by the user. To overcome this issue we will use wiringPi C library in order to create a software generated pulse. Of course the generated pulse will not be as accurate as a hardware generated pulse but will be sufficient for simple tasks involving servo control. In the following picture we can see h ...
