Sample Project:
Circuit:
Code:
void setup() {
Serial.begin(9600);
pinMode(10, INPUT); // Setup for leads off detection LO +
pinMode(11, INPUT); // Setup for leads off detection LO -
}
void loop() {
if ((digitalRead(10) == 1) || (digitalRead(11) == 1)) {
Serial.println('!');
} else {
// send the value of analog input 0:
Serial.println(analogRead(A0));
}
delay(1);
}
