[SOLVED] Voice Control Dimmer Switch

[loveelectronics]

Hello

I am desigining Voice Control Dimmer Switch for my final year project. I am using my SR-07 voice reconigtion kit to recognise the voice. As it show in the circuit diagram A,B,C,D are the output from Voice reconition kit for my voice commands. Switch on and off are working for my voice commands but i couldnt dim the bulb .
any ideas please.

How do i change the resistance for the digital code? (for the dimming)

how do i dim the bulb by using my voice command?

I reckon the first thing to do is to break the input to your opto-isolator and see if you can switch the bulb on/off with DC. To my mind I think there is an error around R4. Normally this sort of pot is used to adjust the phase, but in this circuit it won't do anything? Also the relay coil needs a snubber circuit.
