I added 1.3K ohm(three 3.9K ohm resistors in parallel) between A1 and pin 6. It is working fine. I illuminated 100W bulb for 45 minutes. My triac, mounted with 2cm long aluminium heat sink, just get a little warm. When I connected the 373W electric motor for 2 minutes, the triac(with heat sink)...
Thanks for your reply.
Initially, I have tried only 1K ohm between A1 and pin 6 and 1K ohm at 5V dc anode. That went well with a 5watt bulb and a fan (100 watts approx). But when I tried same with the pump(373watt) triac get too much heated. Which prevents it from switching off. MOC also failed...
I have made the following circuit to control my water pump with Arduino(UNO R3). I have tried many resistors (calculated myself) to limit current in the optocoupler and triac, but failed to carry the load for a long time. At one time either resistor get burned or triac gets too hot. Kindly...
