RemoteSign: {AR?} command (Request Analog Read)

Request the value (0 - 1023) of a pin

Syntax

{AR?} pin

pin - the GPIO (or pin name) of the pin to be read

The value of the pin will be returned by an {AR} command. The pin in the return command will be the same as supplied on the {AR?} command. i.e. if you send a GPIO number you will get that number back. If you send a valid pin name you will get that back.

For example if you send:

{AR?} D5

the reply will be something like:

{AR}D5 ␑ 1023

Note the ESP8266/Wemos D1 supports the following pins:

GPIO 0 (D3)
GPIO 1 (D10/TX)
GPIO 2 (D4)
GPIO 3 (D9/RX)
GPIO 4 (D2/SDA)
GPIO 5 (D1/SDL)
GPIO 12 (D6)
GPIO 13 (D7)
GPIO 14 (D5)
GPIO 15 (D8)
GPIO 16 (D0)
GPIO 17 (A0) Analog to Digital Conversion (ADC)
