analog Read
Read an analog input value from a pin.
pins.A0.analogRead()
Your board can read a number value for a signal on an analog pin. A signal is some amount of voltage
measured by a circuit on your board. The value for that signal doesn’t actually match its
voltage, but it’s a number that means how much signal is there. The number you read for the signal
is something between 0
and 1023
. A 0
is no signal and 1023
is a full signal.
Returns
- a number between
0
and1023
that is amount of signal at the pin.
Example
Read from pin A2
and write the value to the console.
forever(function() {
let signal = pins.A2.analogRead()
console.log("signal", signal)
pause(1000)
})
