A great tool for slacking off in class - Bluetooth 2.0 chat.

Overview

Inspiration:
The inspiration for the usual system of cutting off water and internet access for all teachers came from a teacher who
needed to hand in their phone in the training room. Handing in their phone meant losing access to WeChat.
The plan was to create software similar to a serial port debugging assistant to communicate with a lower-level device, allowing them to contact others.
The PCB demonstration

module can be connected via an external HC05 Bluetooth connection.
