GPIO with Ultrasonic sensor
Hi, I am trying to connect ultrasonic sensor with Metawear RPRO sensor. I did all wire connection,ultrasonic sensor has got transmitter and receiver which has been connected with Pin 8 and Pin 9 .I tried with default Metawear android app to connect through GPIO. In that app I can only give one GPIO pin to connect, but i have two pins. Could you please advice me what do I have to do?
If I create own android app, do I have to create GPIO connection two times? please advice me.
