Last month I received my Arduino Duemilanove board. After doing some basic tutorials I decided to start my first simple project. Why not automate my faithful coffee maker? It would be nice to wake up to a fresh cup.
Some coffee machines can be programmed to brew at desired time. My model is a simple one with an on/off switch. This means I will need a relay to ‘press’ the button, and some timekeeping logic to set the alarm on time.
A sketch of the idea:
For and LCD I’m planning to use an HD44780 compatible LCD, since there’s I can leverage the existing Arduino library.
There will be 5 control buttons:
- Alarm on/off
- Set mode (HH/MM)
- Set alarm/ set time
A 5v relay will be used to trigger the coffee machine and a water level sensor will alert if the water tank is empty.
