HBR-Proportional-Valve
This is an arduino C sketch for controlling a proportional valve with potentiometer joy stick Please include code explanation if you are able Here's what I would use to start my cut & pastry from the Arduino page
/* Read Jostick
-
- Reads two analog pins that are supposed to be
- connected to a jostick made of two potentiometers
- We send three bytes back to the comp: one header and two
- with data as signed bytes, this will take the form:
-
Jxy\r\n - x and y are integers and sent in ASCII

int ledPin = 13; int joyPin1 = 0; // slider variable connecetd to analog pin 0 int joyPin2 = 1; // slider variable connecetd to analog pin 1 int value1 = 0; // variable to read the value from the analog pin 0 int value2 = 0; // variable to read the value from the analog pin 1

// reads the value of the variable resistor
value1 = analogRead(joyPin1);
// this small pause is needed between reading
// analog pins, otherwise we get the same value twice
delay(100);
