in/am/auf: google ring > technology

For the google ring I wan't to use this OLED (organic light emitting-diode) made by Osram. This is a schema which components would be needed to display the 8 digits long google hit counter. If the ring is stored in its casket over night the serial connections RX and TX get connected to a processing sketch. The ring is updated.


Question: Is it possible to plug off the serial connection and plug it on again later without having to reset the microcontroller?
