PART FINDER FRIDAY! When we stumbled upon the PCA9685, we knew we found an awesome chip – its got a free-running PWM driver inside with 16 output channels. You can adjust the frequency to up to ~2KHz, so its great for servos, LEDs or anything else that needs a lot of PWMs. Its 16-bit so its really precise and its free-running so you don’t have to clock it. We turned it into a breakout board but it could be a great addition to a robot controller board.

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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
