microcontroller based remote control

I Need a schematic of irfra red remote controller based on 89c51 or 89c2051 MICROCONTROLLER, the circuit capable to controll the speed of fan and operate on 220 V

i would recommend that you start with PIC microcontrollers. and go to **broken link removed** for a great series of tutorials on PIC microcontrollers. you can find a tutorial on IR there.

in addition to the tutorial the site also has free programmer schematics and free programming software and a support forum.

Use an atmel ATtiny 26

Its perfect for the job.

There are remote control app-notes on atmels site

Then you can go to an ATmega8/16/32 if you need more flash

8051 based remote control

Check the mcu from Zilog. they have dedicated device for IR control.

If i were you, i would probably use a normal Sony remote control available at stores, and then build only the receiver. The 89c51 now are very cheap, i think it's a good option. But i would recommend atmel 89S51 or 89S52, which already supports ISP programming. Hence programming these devices will be much easier. They are still cheap, about the same as the 89c. I use AEC_ISP.exe to program those devices.

Sorry i cannot give any suggestions yet on how to decode IR remote control signals using AT89c51. Please google for yourself, i believe there are many.

Your fan is an AC motor, right? Controlling such motors may require frecuency and duty cycle control of the waveform. I have no experience in AC motors, sorry.

interfacing between micro and ac 220 V you need optocoupler ang try controlling the motor using phase ship method

Why not use a Sharp IR decoding module... GP1UDxx.. they do all the receiving for you pretty much. Choice of micro is irrelevant IMO.

If you have an HP48 calculator you can use that as a IR remote control. It is very easy to reprogram the software for your needs. If I remember right the software is called 'remote'.
Just a guess, ep20k.
