Example code to sample a potentiometer connected to an imp. It makes use of the imp’s ANALOG_IN GPIO pin setting.

analoginPotentio.device.nut

// Alias pin 2 as pot
pot <- hardware.pin2;
 
// Configure the pin for analog input
pot.configure(ANALOG_IN);
 
// Define a function to poll the pin every 0.1 seconds
function poll() {
    // Read the pin and log its value
    server.log(pot.read());
 
    // Wake up in 0.1 seconds and do it again
    imp.wakeup(0.1, poll);
}
 
// Start the loop by calling the poll() function
poll();
