Just an exercise in timers. Oh, it's an arduino-compatable clock.
- Install ino
No idea if it works on hardware yet. Requires a Sparkfun SPI serial display connected to an Arduino Uno via SPI. SS on pin 10.
Time is automatically set from your computer's time when you upload the code.
current_time.h is automatically generated by
deploy.sh so you must use
Connect an LDR on the high side of a potential divider to A6 for automatic brightness control.
Connect a TTL bluetooth serial port to the UART, or just a cable. Commands:
m : increment minute M : decrement minute h : increment hour H : decrement hour
