Flex Sensor Example

One of my students is working on a flex sensor, so I thought I would share some of the code. int myInA0 = 0; void setup() { pinMode(D7, OUTPUT); // onboard LED pinMode(A4, OUTPUT); // PWM //pinMode(A0, INPUT_PULLDOWN); do not set analogRead digitalWrite(D7,HIGH); delay(1000); digitalWrite(D7,LOW); } void loop() { delay(10); myInA0 = (analogRead(A0)-660)/10; // you decide the subtraction and division if (myInA0 <= 0) {myInA0=0;} if (myInA0 >= 250) {m…
