analog Write

Write a value of between 0 and 255 to make a signal at an analog pin.

pins.analogWrite(AnalogPin.A0, 255)

An analog output at a pin will have an amount of voltage related to the output value you give to ||pins:analog write||. You are setting the amount of signal at the pin. You use values between 0 (for no signal) and 255 (for full signal). The actual voltage on the pin will follow the value you give for the output. So, 0 is no voltage and 255 is maximun voltage. The voltage that matches your signal value depends on the voltage range used by your board.

Parameters

• value: a number between 0 (no signal) and 255 (full signal)

Example

Create a sawtooth wave signal on pin A0.

let i = 0
loops.forever(function() {
    i = 0
    while (i <= 255) {
        pins.analogWrite(AnalogPin.A0, i)
        loops.pause(100)
        if (i > 0) {
            i += 128
        } else {
            i += 127
        }
    }
})
