Rgb Led Schematic

Referring to the shown diagram the 4017 ic and the 4060 ic are wired in a standard led chaser mode which is also quite popular with the name knight rider due to its specific running and chasing light effects.

Rgb led schematic. I happen to have a smd type 3w rgb led and i felt that it is important to mention a little bit about that. As said the circuit is built around cd 4029 ic and a few other external components. The resistors will prevent the excess amount of current to flow through the rgb led. In this project we are going to build and operate an rgb led circuit using an arduino microcontroller.

Each led in a section is a 5050 tri color type containing a red green and blue led. The type of rgb led we will use in this circuit is the more common cathode rgb led. Analog type rgb led strips come on a reel and are made of 3 led sections that are 10 cm long. As per the suggested sequence format a simple design using a 4017 ic and a 4060 ic can be used for implementing the proposed rgb led controller circuit.

How to build an rgb led circuit with an arduino. As mentioned earlier a through hole rgb led has 4 leads. The following image shows a common cathode rgb led along with its driving circuit. An rgb led is an led that can light up either red green or blue.

Connect the cathode of the rgb led which is the longer pin of rgb led to the gnd of arduino and the other three pins to the pin 11 10 9 of arduino through the 220 ohm resistors. The finished module can be powered from any clean 5 volt dc supply source for driving the rgb led connected at the output of the circuit. Arduino rgb led circuit diagram.
