Optional Variables

These variables are commented out in the default config.yml and don’t need to be set unless you want to change Rondo’s default behavior. Uncomment and set any that apply to your setup.

Status LED

config key: led_enabled — type: bool — default: false

Controls whether Rondo activates the status LED. When set to true, Rondo will drive the GPIO pin defined by led_pin to indicate its current state.

led_enabled: true

See LED Functionality for a full description of the LED states.

LED Pin

config key: led_pin — type: int — default: 23

The GPIO pin number connected to your status LED. Only takes effect when led_enabled is true.

led_pin: 23

Button Pin

config key: button_pin — type: int — default: 17

The GPIO pin number connected to your push button.

button_pin: 17

GPIO 17 corresponds to physical pin 11 on the RPi 3. If you need to use a different pin, update this value and rewire accordingly. Refer to the Hardware Setup pinout diagram for physical pin locations.
