A battery-powered RGB LED light tube. Built on My Bike's Got LED
It was initallly designed for an active travel game for a local school. In the game participants had to deliver parcels by bike to bollards placed around the playground. Then the game controller then activated the check function. Parcels correctly delivered would show as green bollards, incorrectly delivered parcels as red. A seconf game, 'Red light, green light' was also created were the controller could switch between two light modes to indicate if the cyclists should move or pause. More details of this project can be found on the catalouge page for lightbeam
This repositry contains the hardware and software for these games. The structure is;
The Bollard folder contains the software running on the My Bike's got LED board. It is developed with the ESP-IDF framework and manages Bluetooth communication and the data sent to the LEDS
The Controller folder contains the software running on Micro:bit devices that are used to run the game and send instructions to the bollards. It is developed in Zephyr and sends control messages over Bluetooth.
The Parcels folder contatians the software running on Micro:bit devices that are used as parcels in the game. It is developed in Zephyr and transmits it's identity using Bluetooth GATT services
The Physical folder contains the 3d models for the 3d printed components needed to bake the physical Lightbeam. The files are created in Freecad The README for this folder also contains instructions to assemble the versions of Lightbeam.
