| Abstract: | In this high power LED control system, STC12C5A60S2 is used as MCU chip, the IC ULN2003 with high voltage and large current is as drive chip for high power LED, and DS18B20 is as temperature sensor. The lightness of tri-color led is set by RS232 communication mode and keyboard mode, and is adjusted by PWM mode. As the result, the colorful display of high power LED is realized by this system. Moreover, a good software and hardware experiment platform is provided to students. |
