Here’s a quick project to get some funky flashing \/ colour changing LEDs into your pumpkin. Just grab a set of addressable WS2812<\/a>‘s and some Arduino code and your’re done. \u00a0 \u00a0The 2812’s are pretty easy to wire up. \u00a0Essentially, +5v, GND and data signal get daisy changed through the set of LEDs. \u00a0Each LED has 3 pins for IN and 3 pins out. \u00a0Wire from the Arduino to the first IN set, then from that LED’s OUT set, to the next LED. \u00a0Repeat until all the LEDs you want are connected. \u00a0 Then, load the below Arduino code, ensure you have the right pin assignments and identify the number of LEDs in the string and you’re done. \u00a0Also be careful to monitor the current draw of the LEDs if you are wiring directly to the Arduino. \u00a0Most have current limits and can only power a few LEDs. I managed 5 LED’s with a knock-off Nano just fine. \u00a0 You can always wire power to an external 5V power supply. \u00a0Just ensure you make the grounds common by ensuring both the controller and power supply grounds are connected. \u00a0Check out the video below to see the effects.<\/p>\n
