Do LED lights use PWM?
PWM is a very common method of dimming LED lights that works by very rapidly turning them on and off (pulsing) for periods that visually appear as a steady dimmed light.

Since these strips are 12 volts we will need to use an external power supply. And today we’ll be powering the Arduino.

Next we will connect the power supply to the controller.
Do LED strips need a driver?
Most LEDs require a driver, a few are designed to run on AC current. LED strips also require a driver, but you can buy strip lights separately from the driver, and one driver can supply electricity to multiple LED strips!
Is PWM bad for LEDs?
PWM drives LEDs less efficiently, so they will run somewhat hotter, which could negatively impact their lifespan, although if you are dimming them anyway they will likely be running well below dangerous temperatures.
What is PWM LED driver?
Pulse-width modulation (PWM) is a common type of dimming used to adjust the current in white-LED driver devices. For many smaller format white LED drivers (7-inch screen size or smaller), the PWM signal is converted to a DC control voltage and made to drive the LED current in a DC (or analog) method.
How RGB LED Strips work?
If you combine three colored LEDs together, that gives you over 16.7 million color combinations. An RGB LED light strip works on the same principle. You can control the brightness and color of each strip using an RGB LED controller. Just turn all three colored LEDs to the highest power to create white light.

What is the best frequency for LED controller?
Our recommendation is to utilize LED and DMX dimmers that have sufficiently high PWM frequencies of 25,000 Hz (25 kHz) or above. By utilizing a truly high frequency PWM dimming method, even high frame rate and high shutter speed applications can be operated without any detrimental effects of flicker.
