Schematics

Circuit Diagram For Push Button

*You can choose the mode of triggering the lamp color modes either by push button or IR sensor.
*The code for both the option is same.
*Make all the connections as shown in circuit diagram.
*I have used WS2811 LEDs, I will recommend you to use any addressable LED Strip so that it can be more continent.
