Hardware Setup
Before deploying Rondo, you’ll need to wire your button (and optionally an LED) to the Raspberry Pi’s GPIO pins.
What you’ll need
- Raspberry Pi (tested on RPi 3)
- Momentary push button
- Jumper wires
- (Optional) LED and resistor for status light
Default pin configuration
Rondo uses the following GPIO pins out of the box:
| Component | GPIO Pin |
|---|---|
| Button | 17 |
| LED | 23 |
Both pins are configurable in config.yml via the button_pin and led_pin variables if you need to use different pins. See Configuration for details.
Wiring
Connect your button between GPIO 17 and a Ground pin. Connect your LED (with an appropriate current-limiting resistor) between GPIO 23 and Ground if you’re using status light functionality.
The diagram below shows the default pin locations on an RPi 3:
If you’re using a different Raspberry Pi model, the physical pin layout may differ but the GPIO numbering remains the same.
Next steps
Once your hardware is wired up, move on to Installation to deploy Rondo to your Pi.
