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.

The whole circuit will cost you not more than a couple of dollars. 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. Determines the duty cycle or how long led d1 will be lit in comparison with ledd2. Learn how amazingly simple it is to build a circuit for led christmas tree decoration.

The ornament is a circuit. The white blue and red leds flash at different rates to give a colorful display. Try to use a single piece of copper tape versus cutting it into smaller sections. This section describes the electronics part of the project.

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. 1 36pcs highlight rgb full color led 2 14 kinds of display effects 3 photo sensor automatically adjusts led brightness. This christmas i decided to make christmas ornaments to give to my friends and family. The heart of the electronic christmas tree is a 556 integrated circuit.

No external components are. Christmas leds driver elm711. 3d led christmas tree. The reason for this is because the conductivity is better when there are no breaks.

The flashing christmas tree kit consists of three circuit boards 37 leds that alternate flashing and dual power sources. Using this simple christmas led lights decoration circuit you can make an 18 led flasher to decorate the christmas tree. 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 light sensitive circuit so that it will turn on in the evening automatically and stays on till morning.

Driving an led but in order to drive a string of leds a higher voltage supply and an interface circuit. You will need to apply the copper tape to the brown lines that are found on the template. Led circuit board christmas tree ornament. 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.
