Actually I want to have 1 ground for 4 bulb sets , but dim them seperately..
yeah..its 4 lampsactually 4 sets of 60 5W bulbs
Hi, I made the circuit as I said before. Now I want to connect 4 of these to a load having a common neutral and 4 live in wires. Is it okay to connect the 4 +ve out wires together and give it to the common neutral?
Thanks!. I made the circuit.The bulbs fade out. But I cant figure out a way to fade in. I increased the output value from 0 to 255 in the code, but it won't fade in. It lights up at once and then fades out. Can you tell me a way to fade in the light?

Okay.. Thanks! : )
Thanks.. I made the circuit and its working fine :). But I'm worried because IRF730 and 100k is heating too much. I couldn't find a 6k. So I used a preset for that.I guess its okay. Also I had to use resistors & zenor with higher wattage (like 1W instead of 0.5). Currently I'm checking the circuit with 5 60W bulbs instead of 60 5W bulbs which i intend to use the circuit with. Can you suggest an alternate for IRF730, because I'm somewhat new to this and can't figure out what to choose. Or will it just be okay to use a large heat sink?And I need to keep the PWM pin value at 0 and 255 for longer periods. Like fading the light in, keeping it at 100% for about 1 minute and then fade out and keep it turned off again for 1 minute. I need to do this continuously. Is it okay?
Hi..Thanks for your tutorial. How can I develop this for a higher load..Say about 50 5 Watt 230V bulbs. I need 4 sets of bulbs like this (200 bulbs). I'm going to make 4 of these circuits. But will the MOSFET heat too much and burn out?..
