Plastic gear-box motors (also known as ‘TT’ motors) are an easy and low cost way to get your projects moving. They’re low cost, durable, and easy to use. The trade-off for those low cost hobby motors is that they don’t have any way of knowing their speed or location. Basically you send voltage in and get rotation out. Really expensive motors have encoders built in, and for these TT motors, we’ve now got some simple snap-on encoder wheels.
This TT Motor Encoder is solid, but thin, so it won’t make your robot bulky. It even comes in Adafruit black!
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.
