Description * new and high quality. *Made of high quality material, durable and practical to use. *5V Individual Addressable RGB LED Ring for ArduinoW 812 *These little LED RGB Addressable rings are perfect for adding a of colour to your latest project. Each LED is super fun and glowy and you can control them all individually via your connected Microcontroller including brightness level and any RGB colour you can throw at it, thats right millions of colours at your fingertips *The modules requiree 3 connections to run: A voltage source (5V), ground and a data connection from your microcontroller. You can easily chain as many of these together as you would like, each ring has an "In" data side and an "Out" data pin which you can chain from stick to the other and have data coming in from end *Each LED is technically capable of drawing 60mA when the LED is at brightness in the colour white (Ie. red, green and blue) although in normal colour sweeping modes, it is unlikely that you will ever be running the LEDs at that high of a current. A good rule of thumb when estimating an appropriate power supply is to assume a current draw of 20mA per LED. So if you have 10 LEDs. you will need a power supply capable of delivering 200mA. Having a power supply that can deliver more than the required current is never a bad thing, just make sure that it remains at 5 volts, thats important! Package includes: 1* LED Ring Note: 1. The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness. 2. Please allow slight manual measurement deviation for the data
