About this product
A complete digital clock kit with an Arduino Uno R3 compatible board and USB cable. It uses a DS1302 real-time clock module with a backup battery to keep time when the Arduino is off, and a TM1637 4-digit display shows the time. Three buttons set the clock, set and enable the alarm, and the alarm settings are saved in EEPROM.

Frequently asked questions
Is a computer needed for this kit?
Yes. A computer is needed to upload the Arduino code, using the included USB A to B cable.
Where are the alarm settings stored?
The alarm settings are saved in the Arduino's EEPROM, so the alarm time remains after the Arduino is powered off.
