Điều khiển RGB LED bằng di động

Here's a new project with mobile application. Control an RGB leds with your touch mobile. The symbian OS mobiles are used here. The microcontroller AT89S52 is used to control the leds. Even though the AT89S52 doesn't have inbuilt pwm controller, we use the timers to create soft pwm controller. 

AT89S52 has 3 timers, in wihch timer 0 and 1 are used to control Red and Green leds and timer 2 is used for serial port. blue leds are controlled through the main program. The AUBTM-20 is used to receive the bluetooth signal from the mobile to microcontroller. The bluetooth module works on 9600 baud rate. 

The mobile application is written using python and written for touch screen mobiles. The user can select almost any color from the mobile app. Nokia E7 is used here.
