Serial communication - pratikkhandelwal - 2017 Dec 12
Dan,
Can we not use usb cable for serial communication between arduino and raspberry pi? We are using i2c to communicate between raspberry pi and arduino.

Of course you can use a different kind of cable.

What is this pressure monitor plugin? It shows (Pressure sensor is connected between GPIO pin 22 and ground).
But we are not connecting pressure sensor directly to raspberry pi as shown by pump control plugin. We are connecting pressure sensor to arduino and arduino is connected to raspberry pi. Can you clear my doubt regarding this?
I am getting confused between pump control and pressure monitor plugin. Since pressure sensor monitor plugin is showing pressure sensor is connected between GPIO 22 and ground where exactly we need to connect pressure sensor?
