1W LED Driver Circuit High Power LED lights have lots of applications starting from Emergency lights to Head Lights in some expensive cars. These tiny little things illuminates a lot of area that we expect it to be, in this tutorial we will learn how easy it is to use one and how can we design our own circuit to drive such LEDs based in their operating current. So let us… |

Power LED Dimmer using ATmega32 Microcontroller In this project we are going to use one of the features of ATmega32A to adjust the brightness of 1 Watt LED. The method that is used to adjust the speed of LED is PWM (Pulse Width Modulation). This AVR Microcontroller PWM tutorial explains the PWM concept and generation of PWM in detail (You can also check this simple PWM generator circuit). Consider a simple circuit… |
