Project Completed: My $.99 Christmas LED hat, with ATtiny13 controller

December 18, 2011 | Arduino, diy, electronics, LED | By: Mark VandeWettering

Well, it’s done! Here’s my ATtiny13 controlled Christmas LED hat. It consists of an 8 pin, ATtiny13 microcontroller, a pair of 2N3904 transistors and some 1K resistors, a 7805 voltage regulator with two filter caps, and a switch, all mounted on a Radio Shack perfboard inside an Altoids tin. I’m rather pleased with the way it turned out. I always like it when a project goes from the breadboard to a final mounting in a box.



Addendum: Here’s the schematic for the entire circuit. Nothing too surprising, but you should be able to follow it if you need to.

Very cool !!! Please tell me how to save the battery with Attiny power down sleep. But I need this code with power down sleep.
