LED Menorah Obtaining Power from AVR Tiny13

The project features 9 white LEDs placed on Menorah shaped PCB and is being powered by an AVR ATtiny13 microcontroller.

A Menorah refers to a 7-branched candelabrum which was originally found in the wilderness sanctuary and later used in the ancient Holy Temple in Jerusalem that symbolizes the burning bush as seen by Moses on Mount Horeb. For Hanukkah, it is a 9-branched candelabrum and is a popular motif of religious art in antiquity.

This LED Menorah consists of a circuit board, AVR ATtiny13 microcontroller, 8-pin DIP socket, 2-pin header, momentary pushbutton, resistors, 9 LEDs, and power supply with 2.7V to 3.3V output. The features included in this project include a sleep mode when the Menorah burns out after an hour or so, one button operation, powered by unregulated 3V, and controlled by an AVR ATtiny13. The polarity of the LEDs should be noted during the assembly.

The PCD artwork was created using the tone-transfer method with a ground plane surrounding the layout. This decreases the amount of copper that needs to be dissolved. The AVR-GCC was used to compile the source code while the microcontroller was programmed using the AVRDUDE.
