DESCRIPTION


GitHub repository


A Raspberry Pi acts as a router and provides access to a LAN through Wi-Fi for devices. An API server runs and responds to HTTP GET, POST and DELETE requests by updating or reading a SQLite database. A web server also runs on the Raspberry Pi to provide a web application that allows
patients to submit their calls and volunteers to delete and view the calls. Another Raspberry Pi that connects to the LAN is used as a button. It sends a predetermined HTTP request when the physical button is clicked and is programmed using Node-Red.
