Presence Light
Project Reason:
I have thought of this project, because coworkers walk 100 meters shaking the whole building just to see that the guy(coworker) behind me is not in his seat.
So i thought: "Why not make something, where he(guy behind me) can signal his presence.
I will create the project in parts or sub-projects:
LoRa Sender and Receiver with Dormant and RTC Alarm (RP2040)
This project focuses on the DORMANT mode of the RP2040. Furthermore the SX1278 is used to establish an encrypted communication between a sender and a receiver device. While saving energy through the DORMANT mode is the essential topic here, the GPIO-Wakeup(sender) and the RTC-Wakeup(receiver) are the key to save power but also be able to communicate.
