hi everyone I'm new in here nice to meet you ; D
I design to use D flip flop to switch on - off lamp by using cd4013 > moc3020 >Triac (bta16)>lamp
schematic
problem is
-when turn on main switch the output 1 was high ( some time )
-when the turn off relay comeback to nc output 1 was high ( mostly )
*** I don't connect to load yet just only cd4013**
I solved by using R+C+diode to soft start supply
but
when i connect to load ( optocoupler+triac+lamp) that problem comeback again
how to solve this plesae help me : (
