- Connect one of a soft switch to your Arduino. Use it to control an LED.
I decided to try out Lily tiny ( ATtiny-85). It quite tricky to set up and to control as desired. I got to control the LED with my soft switch.
2. Build a circuit with one constructed sensor (variable resistor), your Arduino, and 3 (or more) LEDs or an RGB LED.
I tried with the Lily tiny but I didn’t manage to control the analog input properly. So I switched back to the Arduino UNO. I created a switch with copper fabric and Velastat that allows me to control the Leds easily.
I wanted to create a stretchy switch with a french knitter, but I could use conductive yarn, so I used regular yarn.
It looks nice I could use it in the future.
I’m planning on creating an interactive scarf. A very handy piece for those cold winters to measure the intensity of those persistent sneezes.
I have to figure out some details, such as how to control the signal with the lily tiny or how to power the system without wires.
