I have always wanted to control something interesting involving little servo motors. That’s somewhat of an ill-defined dream, isn’t it? But it has all been made possible by using my handy dandy Raspberry Pi computer. I spent quite a bit of time this past year on another project that involved reading signals from almost a dozen temperature-humidity sensors and reporting status details to a remote web server. That project is now unfortunately stuck on the backburner, but at least it got me started doing interesting things with my Raspberry Pi.
In this post I report on my current side project, which involves my Raspberry Pi, five servos, my son’s Lego blocks, and synchronized groovy music. Let’s get right to it: the final result is a video hosted on my YouTube channel. I recommend watching it full screen on a device with decent speakers. Enjoy!
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)
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
