    Dear Sir,

    I want to make the project using 89c51 microcontroller 10 channel remote control switches and 4 individual fans using rc5 codes and the status shows on LCD also it will
    Remember the previous operations power failure so please I want the code for my project can you help me in my project.

    When command send from remote LCD should glow with status suppose 1 channel is on the it will show 1 on lcd and so on individual operations also show fan speed

    Regards,

    Controlling 10 devices is not a problem, but controlling 4 fans need some tricky codes. Since in my code each fan needs a timer. The 8052 controllers have only 3 timers so we can control only 3 fans.

    For connecting the LCD please go through the tutorials on the CODE LIBRARY page.

    PLZ CORRECT THE CIRCUIT. PIN NUMBER 16,17 i,e.P3.6,P3.7 ARE IN THE CODE MENTIONING ABOUT SOME SWITCHES BUT NOT USED THE CIRCUIT. THE 7 SEGMENT DOES NOT HAVE EITHER SERIES RESISTOR FOR EACH SEGMENT OR A SINGLE ONE AT THE COMMON ANODE.

    I will go through the code and i will reply afterwards.
    Regarding the EEPROM the AT89S8252 is used for this code. This type of IC has an inbuilt EEPROM of 2Kb. But you can also use external EEPROM and the code is to be changed accordingly.

    All RC5 remotes or 90 channel remotes can be used for this code.
