Is it possible to use the digitalWrite function on an analog pin(A4)? This is possible on Photon but not sure if it is possible on Bluz or not. I am trying the following:
pinMode(A4, OUTPUT); digitalWrite(A4, HIGH); delay(2000); digitalWrite(A4, LOW);
I do not see the analog pin going high or low. If just stays low.
If this is not possible can you do an analogWrite(not PWM) to set the voltage output of the Analog pin?
