Here's a small Big Clock LCD Display I worked on, so I could display some agenda stuff, have alarms, etc ...



Gear used:

- Arduino nano (coded for the old ATMEGA168, but works with the new ATMEGA328 too)
- RT Clock + EEPROM
- Big 20 x 4 LCD Display
- Ultrasonic Sensor Module
- Buzzer

I will post the code and also links to each part I used after this.

The device is a custom clock with agenda and special alarms. Up to 50 events in the alarm, with option of recurring events, simple reminders and daily alarms. The ultrasonic sensor allows you to switch off an alarm, or display the entire agenda-events. The LCD will display a BIG Time, small Weekday/Day/Month (its all done in Day/Month format, sorry) plus the next event in the agenda. (if its a fixed-day event, not a daily event) The unit is programmed via serial, so its always connected to my PC. But when my PC is offline, it will still work since its totally self-contained. (serial use is just to set clock and events/alarms)
