read
Read an analog pin value as a percentage of total possible input.
sensing.read(AnalogPin.A0)
The input on the pin is read as a percentage of the total voltage possible. So, if the pin can have a maximum of +3V but there is only +1V of signal on the pin, then a value of 33
is returned.
Parameters
- name: the name of the pin to read the input percentage value from.
Returns
- a number which is between
0
and100
as a percentage of total possible input.
Example
If the value at pin A0
is greater than 50, light the LED at pin D4
.
loops.forever(function() {
if (sensing.read(AnalogPin.A0) > 50) {
lights.set(DigitalPin.D4, 1)
} else {
lights.set(DigitalPin.D4, 0)
}
loops.pause(100)
})
