Simple clock that always shows the correct time. GPS reception required.
GPS-synchronized-clock
Simple clock that always shows the correct time. GPS reception required.
Selection between summer time and winter time must be done manually.
Only a few components and easy to build even on a breadboard
Built around an ATMEGA328P chip or board
To fit the glass dome, use an Arduino Mini Pro 5V version
or
ATMEGA328P chip supply voltage 5V
The LED matrix is not 3.3V compatible.
When using the ATMEGA328P chip, use the following settings:
Bootloader: "No bootloader"
Clock: "Internal 8MHz"
No impact on your finances
Ideal for Arduino beginners
Serial communication
I2C communication
SPI communication
Analog input
Digital input
Interrupt subroutine
Use of a 2-dimensional array
Nice end result
