ATTiny Fun.

The tree arrived last Sunday and with it my age old worry about it drying out before Christmas. In a house as busy as ours this is a big issue.

Enter Atmels ATTiny85. This is a small easily programmable micro controller for under $2. Just add a coin cell battery an led, buzzer, battery, some wire and a box to put it in and you’ve got a low water alarm that sings Jingle Bells when the water gets to low.

Below are some pics of the almost finished product. And here is the link to the project.

Merry Christmas!
