How to Get Responsive Stitches with Powerful Tiny Tech #WearableWednesday #wearabletech #tech #fashion #Arduino
Stitchable microcontrollers are great for sewing projects which need plenty of pads for inputs and outputs. However, what if you have a tight space where you only require minimal connection? Liza Stark has created some beautiful embroidery which nicely demonstrates the answer—an ATtiny. Think of it as the turkey without the trimmings. It’s small and inexpensive, but you do have to take some extra steps for programming since it doesn’t have a bootloader. Check out this Instructable which shows how to get the job done with an Arduino, which you probably already have at home.
Liza is doing some fun stuff with her circuit creating switches by using thread and touch in different ways. Her project can illuminate LEDs by bridging two areas of stitching with a finger, drawing two loose ends of yarn together or by pushing an accessory crocheted flower button that also uses conductive thread. All of this work is perfectly aligned with Liza’s experimentation in soft circuits. If you are a crochet or knitting fan, be sure to check out her Conductive Granny Square. If you are curious about how to link tiny parts to conductive thread, also look at my post on Making Awkward Electronics Stitchable. Finally, the best advice I can give on doing soft circuits is to invest in a Digital Multimeter. I can’t tell you how often I’ve had to use the audible continuity feature. Listening for the beep is not only fun, but it means things are working! Have fun with your own conductive thread experiments and let us know what you make.

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.
