Progress
- Tested Arduino Pro Mini with blink example
- Tested IR receiver with IR led, as well as TV remote controller
- Tested nRF24L01 wireless transceiver
Difficulties
- IR emitter is much lower than expected [suggestion from Matt: use an NPN (bjt or mosfet) transistor to supply more current]
- Order ring shape dotstar
Next Steps
- Test communication between multiple nRF24L01 wireless transceiver
- Check communication protocol between arm, weapon and pickup group
- Design iteration: meeting with other groups about the size of different components
- Notification system design with Buzzer/microphone and dotstar

Progress
- Tested communication between two nRF24L01 wireless transceivers, send & receive signal successfully

Questions
How big is the LedRingAddedBackground PCB?
It measures 80.2 × 80.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LedRingAddedBackground use?
24 parts, built around the APA-102C-NEW. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the LedRingAddedBackground KiCad files?
From the moonbeaminteractive/feedback-vest repository on GitHub, at the commit this page was made from: the board is hardware/LED Ring/LED Ring/Schema and PCB/ledRingAddedBackground.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LedRingAddedBackground design in my own project?
Its repository states no licence, so its author keeps all rights: ask moonbeaminteractive before reusing the design.
