RGB LED Blinking Christmas Tree

thingiverse

This is a bright green-red-blue LED blinking light Christmas tree that stands out in any holiday setting. It starts with a versatile PSOC 4 prototype board, the CY8CKIT-049 4200, which you can purchase for just $4 and gives this project its robust foundation. All of the project details including schematics and C code are freely available on GitHub at https://github.com/peter-gregory/BlinkingTree.git. To get started, download and follow these instructions to build your own LED tree. Before starting, note that STL files for printing are given in inches, so if they appear tiny on screen you will need to scale them by 25.4 to switch them to millimeters, giving the desired print size. Fortunately, parts were designed with support-free printing in mind. Peter Gregory printed these tree pieces on a Cubex Trio using a single color and they come together with a smooth fit. Assembling the lights requires attaching wire leads to LEDs and securing them inside the tree's central space using ribbon cable for easy access and durability. For seamless lighting, plug 16 LED matrix lines directly into the board.
