Captures everything needed to redeploy the two-display clock (hour on I2C 0x61, minute on I2C 0x63) on a fresh Pi: - Both systemd units (matrix0x61.service, matrix0x63.service) - Deployed Pimoroni script tree, including the local %I (12-hour) clock customization - Vendored upstream sources (ltp305-python, breakout-garden) so restore is fully offline-capable - Boot config snippet enabling I2C - install.sh that wires it all back up idempotently - Inventory doc cross-referencing every live-system path Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
UV warning example
This example uses a VEML6075 UVA/B sensor, a 5x5 RGB matrix, and a 1.2" OLED breakout to display average UV index as a traffic light warning on the RGB matrix, with green being a low UV index, yellow/orange being moderate, and red high or extreme. The numerical values and a descriptive warning are displayed on the OLED.
Pre-requisites
This example requires:
- A Pimoroni Breakout Garden
- A Pimoroni VEML6075 UVA/B Sensor Breakout Breakout
- A Pimoroni 5x5 RGB Matrix Breakout
- A Pimoroni 1.12" OLED Breakout (SPI)
Installation
Pop the breakouts into your Breakout Garden, and then run the install.sh
script in the root of this repository with sudo ./install.sh to automagically
install the libraries to run the I2C breakouts.
For this example you'll need to make sure some additional software is installed:
sudo apt install python3-pil
You'll need to clone and install the library for the 1.12" OLED Breakout (SPI) as follows:
git clone https://github.com/pimoroni/sh1106-python
sudo ./install.sh
This example assumes that you have the OLED plugged into the front slot on the
Breakout Garden HAT, which should also work with the Breakout Garden Mini HAT.
To change it to the back slot, change device=1 to device=0 on the line
where the OLED is set up.
Running this example
To run this example, type ./uv-warning.py in the terminal
Notes
You might want rotate your Pi and Breakout Garden so that the UV sensor is facing upwards at a better angle to detect UV light.
