Frustrated by the fact there there is only one easily accessible PWM output on your Raspberry Pi? Then this article is for you, because now you can use ANY GPIO pin as a PWM output thanks to the latest addition to wiringPi…
The latest addition is a software driven PWM generator that runs as a thread in the background of your program managing the outputs of the pins in a PWM manner. It can be used to control any number of pins on your Pi – from 1 to all 17 if desired.
For driving servos, also try our 16-channel PWM/Servo driver (tutorial here) for basic LED dimming Gordon rocks it out!
Each Friday is PiDay here at Adafruit, be sure to check out our posts, tutorials and new Raspberry Pi related products. Have you tried the new “Adafruit Raspberry Pi Educational Linux Distro” ? It’s our tweaked distribution for teaching electronics using the Raspberry Pi.
