Getting back to pComp had me feeling somewhat anxious, since it’s been quite a long while since I’d built any kind of circuit. I didn’t have the supplies any more, so purchasing a new Arduino, breadboard, and sensor, was almost like back-to-school shopping (except no new Transformers trapper keeper or sweet smelling markers – heh). During the first week of class, my original intention was to work with posture and pressure sensors placed on my bottom, lower back, and upper back. However, the demo from class two inspired me to do a project with breathing and the stretch sensor. I don’t have a focused concept worked out yet, but I was successful in getting a decent range of numbers from the Arduino with some basic code and wiring. See a brief video below.

int analogPin = 3;
int val = 0;
void setup() { Serial.begin(9600); }
void loop() { val = analogRead(analogPin);
Serial.println(val); }
