Want to program a pin that spells out messages or a pendant that changes color? In this creative, hands-on workshop, you'll meet the BBC micro:bit and AdaFruit Circuit Playground Express, tiny, battery-powered computers called "microcontrollers" that are small enough to wear. Using MicroBlocks, an easy-to-learn blocks language similar to Scratch, you'll write code to make these devices display animations, respond to buttons and tilts, and more. Never programmed before? No worries, we'll help you get started. Sorry, you can't keep the microcontrollers, but we'll tell you where you can buy your own for just $20-$30.
