The following program will read the analog inputs A0 and A4, and display their values on the serial console.
int ADI_Value0; int ADV_Value4; void setup() { Serial.begin(9600); } void loop() { ADI_Value0 = analogRead(A0); delay(100); ADV_Value4 = analogRead(A4); delay(100); Serial.print(" CH 0 = "); Serial.print(ADI_Value0); Serial.print("\n" ); Serial.print(" CH 4 = "); Serial.print(ADV_Value4); Serial.print("\n\n" ); delay(200); }
