We’ll be going over different robotics packages and shields available to the pi, and
implementing code to control servos using Adafruit’s 16 channel PWM driver. I’ll be
demoing the code with my mecanum platform, which was built for the raspberry pi.
Time permitting we will also cover communicating with an Ardunio over a serial usb
Adafruit 16-Channel 12-bit PWM/Servo Driver – I2C interface – PCA9685 – You want to make a cool robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise PWM output. Then you realize that your microcontroller has a limited number of PWM outputs! What now? You could give up OR you could just get this handy PWM and Servo driver breakout. (read more)
