Dimmer Brightness LED Driver Circuit Diagram
This is a very simple circuit of a dimmer, ie a controller LED brightness, which is powered from the USB port of a PC and a connection is very simple. The resistor R1 sets the maximum current of the LED with the maximum potentiometer, resistor R2 should have a resistance of 10x to 100x greater than R1. The table shows which components to use in accordance with the selected LED. Dimmer-Brightness LED Driver Circuit Diagram
