pixl.js with analog moister sensor

Good news!

Even got it work on a esp32 with espruino
Here is the code

var high = 0.5;
var low = 0.0;

function map_value(val, in_min, in_max, out_min, out_max){
  var result = (val - in_min) * (out_max - out_min) / (in_max - in_min) + out_min;
  
  if(result < out_min) {
    return out_min;  
  } 
  else if(result > out_max) {
    return out_max;
  }
  
  return result;
}

function onTimer() {
  var h = analogRead(D35); // D35 is a adc-port (analog to digital converter)
  var hp = map_value(h, low, high, 0, 100);
  var percentage = hp.toFixed(0)+"%";
  
  console.log("Soil moister", percentage);
}

// Update soil moister every 2 seconds
setInterval(onTimer, 2000);
// Update soil moister immediately
onTimer();

To bad there are no bluetooth support yet :(
