This document outlines goals for a device that can switch and set alarms for four devices using a browser or mobile app over LAN or internet. It proposes designing an embedded server using an Arduino board for WiFi communication via ESP8266 that isolates devices via relays. An Android app would communicate via HTTP to control devices through an algorithm integrated with the embedded server.

2. GOALS
• CAPABLE OF SWITCHING FOUR
DEVICES
• SETTING ALARM TIME FOR EACH
DEVICES
• CONTROL DEVICES OVER
BROWSER + MOBILE APP
• CONNECT WITH BOTH LAN AND
INTERNET
• FRIENDLY INTERFACE; OPERATE
ACCURATELY, RELIABLY
