Abstract

In this work, a universal LED driver is proposed based on micro controller. The main function of the driver is to drive different current levels to power LEDs. Pulse width modulation is changed through micro controller in order to change output current. Two power LEDs with current rating of 350 mA and 700 mA respectively have been selected as load and a micro controller, ATmega328 programmed through Arduino UNO has been selected to change the current level. Proposed design is simulated and a prototype is designed and the validity of the designed driver is verified.
