Markus Gritsch posted an update on his Dot-Matrix MSP430 alarm clock we covered previously:
Using the ADC is a good suggestion. Thank you!
The clock now has an additional state after turning the flashlight off, where it displays the battery voltage in volt.
I also added an additional displaying mode where it uses dice symbols for the digits. In the following picture the time is 14:27:36 and the alarm is active (on).
