How To Make A Simple LED Driver

I show how to make a simple high power LED driver, for LEDs ranging from 1 Watt to 40 Watts. You can adjust this driver by changing a potentiometer. Link to the video of the LED driver working: Link to LM317 resistor value calculator: To set up the driver for an LED you first figure out what voltage the LED is rated for. Then you connect the output leads from the led to a volt meter and adjust the driver to the proper voltage. DO NOT EXCEED THE RATED VOLTAGE FOR
