LED Strip Dimmer
This LED DIMMER is an Arduino Uno based PWM (Pulse Width Modulation) circuit developed to get variable voltage over constant voltage. The method of PWM is explained below. Before we get start building a 1 Watt LED Dimmer circuit, first consider a simple circuit as shown in figure below. Now if the switch in the figure is closed continuously.

Make sure your MOSFETs are logic level and not standard. Connect Arduino pins 9, 6, and 5 to the gate legs of the three MOSFETs, and connect a 10k resistor in line with each to the ground rail. Connect the Source legs to the ground rail. Connect the Drain legs to the Green, Red, and Blue connectors on the LED strip.

Schematics In this example, the WS2812B LED strip will be powered using the 5V Arduino pin. In my case, I'm controlling 14 LEDs. If you want to control many LEDs, you'll need to use an external power source. Useful tips: Connect a capacitor with a capacitance between 100uF and 1000uF from power to ground to smooth out the power supply.
