arduino switch platform allows you to control the digital pins of your Arduino board. Support for switching pins is limited to high/on and low/off of the digital pins. PWM (pin 3, 5, 6, 9, 10, and 11 on an Arduino Uno) is not supported yet.
To enable the Arduino pins with Home Assistant, add the following section to your
# Example configuration.yaml entry switch: platform: arduino pins: 11: name: Fan Office 12: name: Light Desk initial: true negate: true
(map)(Required)List of of pins to use.
The digital pins are numbered from 0 to 13 on a Arduino UNO. The available pins are 2 till 13. For testing purposes you can use pin 13 because with that pin you can control the internal LED.
