Soda can clock

The clock is using an Arduino pro mini, the DS3231 real time clock module, the Nokia 5110 LCD display and a 18650 Li-battery with a charger module. The code for the Arduino was explained in a previous project. However, some improvements were made concerning power consumption an therefore the code was updated and uploaded (see Instructables link above) as supporting file in step 4. With a 2900 mAh battery the clock is running for 4 month.
