Hello. I need help about an IR remote control that can manipulate 3 light bulbs (typically 12v).
I thought of a remote control with 9 buttons that would transmit 9 different frequencies than will be received by a frequency decoder (??).
buttons:
1-red bulb (on/off)
2-green bulb (on/off)
3-blue bulb (on/off)
4-red bulb (increase intensity)
5-green bulb (increase intensity)
6-blue bulb (increase intensity)
7-red bulb (decrease intensity)
8-green bulb (decrease intensity)
9-blue bulb (decrease intensity)
I thought of using 555 timer in the transmitter to produce 9 different frequencies... the output of the 555 timer is connected to an IR LED to be transmitted.
I want to ask what IC can be used to detect a unique IR frequency that would trigger the certain operation indicated by the button numbers above.
I also want to know what circuit should I use to change the intensity of the light bulbs using remote control.
Please help me. I appreciate your reply. Thanks.
