Connecting a cathode led driver#

The working of the driver circuit is also very simple, The LEDs that we have used in the circuit are all common Anode LEDs, and all of them are connected in parallel. The complete schematic diagram of the color changing RGB LED Tree is shown below the circuit is very simple and easy to understand. Components Required to Build LED TreeĬomponents required to build the RGB LED Tree are simple and can be found in your local hobby storeĬircuit Diagram - Color Changing RGB LED Tree For a common anode LED connect this pin to VCC, for common cathode LED it should be connected to the ground. +/- Pin The (+) and (-) pins represent the common cathode or common Anode Pins of the LED. and if the LED is a common cathode, connecting it to VCC will light up the LED. Pin B In case of a common Anode LED connecting the B pin to Ground will light up the LED. Connect the G Pin to VCC in case of a common cathode LED. Pin G Connect the G pin to Ground in case of common Anode LED. Connecting it to Ground or VCC will light up the LED Red.

Pin R The negative terminal of the common Anode LED or the positive terminal of the common cathode LED depending upon the common Anode or common Cathode configuration. The common Anode LEDs have RGB in common and There are two types of LEDs common anode and common cathode and for this project, we will be using common anode LEDs. The pinout of the common anode and common cathode RGB LEDs are shown below. The lighting system built in this way is not only efficient but cost effective but it can also create stunning color effects that can transform any room. The building process is simple and requires only a few transistors, capacitors and resistors to build it. In this short tutorial, we will show you how you can build yourself a transistor-driven color-changing RGB LED lights.
