Wearable Tech Projects: a light-up bag #Adafruit #CircuitPlaygroundExpress #MakeCode #Wearables @SophyWong @HackSpaceMag @Adafruit @MSMakeCode

From the new book Wearable Tech Projects by Sophy Wong – Flaunt your skills with a light-up bag! Make an interactive tote bag with a Circuit Playground Express, Microsoft MakeCode, and a little sewing.

Need a project idea for your brand new Circuit Playground Express (CPX)? Make it a wearable one! The CPX has oodles of sensors and NeoPixel LEDs built in, so no soldering or breadboarding is required to set up a circuit. You’ll want to take it with you everywhere so you can tinker whenever inspiration strikes you.

In this project, we’ll sew it onto a tote for coding on the go! The CPX is a little powerhouse, and we’ll use the on-board accelerometer, capacitive touch capabilities, and ten NeoPixel LEDs to run some fun animations on the front of the tote bag. To make our program interactive, we’ll add snaps for simple touch-sensitive buttons. Each button will play a different NeoPixel animation when pressed. While we’re at it, we’ll use the accelerometer to trigger a flashy animation if you happen to run, skip, or jump while out and about with your bag.

The project in this tutorial is programmed in Microsoft MakeCode – the easy to use block-based language (although if you’re comfortable with CircuitPython, that is an alternative not reviewed in the tutorial).

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