Today I worked on a mini project for a forthcoming workshop at Somerset House (London, UK).
I used a Gemma with a soft potentiometer (Plug & Wear) and a neopixel strip.
I took inspiration from this Adafruit post: https://learn.adafruit.com/textile-potentiometer-hoodie/prepare-and-sew-sensor.
Unfortunately the code they posted wasn’t complete so I had to figure out how to make the Gemma work with the wearable sensor and the LEDs.
If you see the picture below, you’ll be able to have a look at the pins connected.
The Neopixel strip (5 Neopixels in total) is connected to:
GND: Ground (Black wire)
Vin: 5V (Red wire)
Pin 1: Signal (Green wire)
On the other side we have the soft potentiometer sewn into:
I am also using a small LiPo battery (110mAh) to power the circuit.
Below the code
The idea is to control how fast the LEDs blink thanks to the soft potentiometer
