<h2><b>Remote Controlled Multicolor Fountain Illumination</h2></b><h1>Fully Customizable with Neopixels</h1><p><h2><b>Controlled by Your Smartphone or Remote Control</h2></b><p>\r\n<p>\r\nWatch the video: <a href="https://youtu.be/GaHKx8XjSXA">Remote Controlled Fountain Illumination with Neopixels</a><p> \r\nThis remote controlled illumination is designed for a waterspout fountain in my garden pond. The fountain has a 20 mm diameter water pipe.\r\nI created a waterproof cover for a ring of 40 neopixels (126 mm diameter) which is located just beneath the outlet of the fountain and secured with \r\n\rna cable tie. To make it waterproof, I filled the cavities with two-component epoxy glue (Uhu plus schnellfest). It works perfectly! The ring is connected \r\n\rnby wire to a small Arduino-based controller board outside the pond. This board is housed in a waterproof case as well. It has a small window for \r\n\rnthe IR receiver.\r\nSince I encountered issues with the timing between the neopixel library and infrared library in the Arduino, I decided to build a dual Arduino \r\n\rnconfiguration. One Arduino controls the neopixels, while the other handles the infrared signals from a remote control. Both are connected by 1-Wire interface (sda/sdc).\r\n\r\n<h1>What You Need:</h1><p>\r\n<ul>\r\n<li> Neopixel ring with 40 LEDs (diameter 126 mm)</li>\r\n<li> Acrylic glass ring, 3 mm thick (see drawing)</li>\r\n<li> Approximately 15 g of 2K epoxy glue (e.g. Uhu plus schnellfest)</li>\r\n<li> Plastic glue (e.g. Uhu hart Kunststoff)</li>\r\n<li> Cable tie to secure the ring holder on the water pipe</li>\r\n<li> 2 cable glands PG7</li>\r\n<li> 3 - 5 m black waterproof low voltage cable (3 pol.)</li>\r\n<li> Waterproof wall mount power supply, 5 V</li>\r\n<li> 4 countersunk head screws M3x8</li>\r\n<li> Controller board (feel free to create one)</li>\r\n<li> Infrared remote control (I used a faytech from an older monitor)</li>\r\n</ul><p>\r\n\r\n<b>Instructions:</b><p>\r\n<p>\r\nPrint the part neopixelholder.stl with support and 90% infill.\r\nGlue the neopixel ring to the acrylic ring using small portions of plastic glue to secure it. Now, attach the neopixel holder as well to the \r\n\rnacrylic ring so that the neopixel ring is completely covered and centered. The already soldered cable passes through one of the holes. If this has become \r\n\rnstuck, fill the cavities of the now covered neopixel ring through the holes with 2K epoxy glue. This works easily if you use the two-component glue \r\n\rnin a cartridge with a static mixer. Ensure that all the cavities are filled and everything is sealed properly. Connect the other end of the cable to \r\n\rnthe controller electronics.\r\n<p>\r\nYou can change the color programs (pulsing, static color, rotating pixels, rainbow, etc.) using the remote control. It also allows you to switch to \r\n\rnstandby mode (leds off), change colors in the programs, and adjust brightness. Check out the source code for more information.\r\nTo program the Arduinos, you'll need a serial breakout board connected to the 6-pin programming interface. Each Arduino on the board must be programmed with \r\n\rnthe corresponding sketch. <p>\r\nSketch I2CNeopixelSlave.ino is used to trigger the Neoppixels.<p>\r\nSketch IRReceiver1.ino handles the IR receiver and the other Arduino.<p>\r\n<p>\r\nHave fun!
