Analog Read Pin

Read an analog signal (0 through 1023) from the pin you say.

pins.analogReadPin(AnalogPin.P0)

Parameters

• a string that stores the pin you say (P0 through P4, or P10)

Returns

• a number from 0 through 1024

This program reads pin P1 and shows the number as a bar graph.

    let value = pins.analogReadPin(AnalogPin.P1)
    led.plotBarGraph(value, 1023)
});
