Led Circuit Board Christmas Tree

I ve been learning kicad this year so i decided to make the ornaments out of circuit boards.

Led circuit board christmas tree. 3d led christmas tree. It uses the pic12f683 microcontroller that operates at 4 0mhz using the internal clock source and drives 20 leds through 5 i o pins gp0 gp1 gp2 gp4 and gp5 using the charlieplexing technique. The whole circuit will cost you not more than a couple of dollars. The flashing christmas tree kit consists of three circuit boards 37 leds that alternate flashing and dual power sources.

This christmas i decided to make christmas ornaments to give to my friends and family. The white blue and red leds flash at different rates to give a colorful display. I made about 20 25 of these ornaments. It is a light sensitive circuit so that it will turn on in the evening automatically and stays on till morning.

The heart of the electronic christmas tree is a 556 integrated circuit. The reason for this is because the conductivity is better when there are no breaks. Now it s time to make the circuit that will light your christmas tree. Learn how amazingly simple it is to build a circuit for led christmas tree decoration.

1 36pcs highlight rgb full color led 2 14 kinds of display effects 3 photo sensor automatically adjusts led brightness. Using this simple christmas led lights decoration circuit you can make an 18 led flasher to decorate the christmas tree. The ornament is a circuit. Led circuit board christmas tree ornament.

The circuit will provide a varied flashing display rate to the leds which may be positioned at different points over the christmas tree. It is a flash christmas tree kit consists of three circuit board allows 36 led flash alternately showing a christmas tree in the space of three dimensional profile the night environment has better viewing. Driving an led but in order to drive a string of leds a higher voltage supply and an interface circuit. This section describes the electronics part of the project.

The flash christmas tree kit consists of a combination of three circuit boards the user through their own welding assembly so that the 36 led alternating flashing in the space of a christmas tree in the outline of the three dimensional night environment to see better. Try to use a single piece of copper tape versus cutting it into smaller sections. No external components are. Determines the duty cycle or how long led d1 will be lit in comparison with ledd2.
