-Initially, the box is in the CLOSED state, where the motor isn't being acted upon, it's display has the "CLOSED" text, IP address and the box is considered closed.
+Initially, the box is in the OPEN state, where the servo is at a 90 degree angle, the display has the "OPENED" text, IP address and the box is considered opened(lid up).
-After the user presses the button on the page, the box plays a sound, the motor activates to lift up the cover of the box and the displayed message changes to "OPENED". A second message will revert to the initial state.

    * **Battery: Supplies the whole circuit. Has enough power so that the servo can function multiple times. It's also very efficient in the idle state, as only the display and microcontroller are active most of the time.**

 ==== Calibration ====
-The servo was calibrated according to this [linku rnt sg90] and does a 90 degree turn. The display was calibrated using [linku rnt display]. There is also a delay in place for the client reply to lower the HTML responses sent and also save power.
+The servo was calibrated according to the first link in the software section and does a 90 degree turn. The display was calibrated using the 3rd link. The timeout is 10s, because a mobile hotspot could be a bit slow at times, in a real scenario this should be <1s.
 ==== Functions ====
+    *onTimeout() - interrupt function that sets the timeout flag to true
+    *startClientTimer() - function that resets and enables timer
     *buzz(int duration) - makes a sound for the provided duration
