When eggs are put in this “novel egg holder”, the device will automatically calculate the quantity and display on the 7-segment display. When the holder is full, the green LED will turn ON, and when there is still has space, the blue LED will turn ON; when there is no egg in the holder, the red LED is ON and the device will send a voice reminder.
