This holiday season, let the littleBits Robot Butler pass the food around the table for you. This smart little creature roams the table on a central wheel that is connected to a dc motor. Little plastic laser-cut arms activate three roller switches on the side as they bump into cups and bowls, causing the robot to turn and try elsewhere. This happens because there is an inverter in between the first dc motor and a second dc motor positioned on the edge. For more information about the circuit, click here. To make your own, follow these instructions.

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.
