readVoltage

Read analog pin voltage on BBC micro:bit board

Syntax

voltage = readVoltage(microbitObj,pin)

Description

voltage = readVoltage(microbitObj,pin) reads the voltage on the analog input pin on the BBC mico:bit board, specified as a microbit object.

Examples

Read Voltage from Analog Pin

Create a BBC micro:bit object and read voltage from an analog pin.

microbitObj = microbit('COM3');
vp10 = readVoltage(microbitObj,'P10')

vp10 =

3.3000

Input Arguments

microbitObj — BBC micro:bit hardware connection

microbit object

BBC micro:bit hardware connection, specified as a microbit object created with the microbit function.

pin — Analog pin number

character vector

Analog pin number on the BBC micro:bit board, specified as a character vector.

Example: 'P0'

Output Arguments

voltage — Value read from analog pin

double
