First up, the PCA9685 16×12-bit Servo PWM board (above), which is capable of driving up to 16 servo motors at once. All those motors need a good amount of current, so it’s best to use a separate power supply — easily added with our 2.1mm-to-terminal block adapter (above, top). The PCA9685 Fritzing part behaves just like the real part — all the GND and V+ lines are bussed together, as are the I2C terminals on either end.

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.
