Remote Controlled AC Fan Regulator PCB

This device can be used to remotely control the speed of an AC fan and to switch it on or off. The remote control is a cheap NEC Format remote, usually supplied with small DVD players. Three buttons are used to command the circuit. The UP key increase the fan's speed while the DOWN key decrease it. The ENTER key is used to switch on or off the fan. The unit provides 10 way speed control from 0 to 9. The current speed is displayed in a seven segment display. The yellow LED on the PCB indicates the power status of the load. If the load is switched off using the R/C then the LED will also be switched off.
