hello
Anybody know, why my micro restart when I drive solenoid valve with optotriac and triac?
And anybody know how can I drive solenoid valve without any problem?
Please help.

You're not giving us much to work on.

No hardware, no software.

However, I'm assuming that the re-start happens just after you drive the solenoid.

In which case you need to look (for starters) at cable layout, board layout, PIC de-coupling, RC snubbing the solenoid, I/O cables to/from PIC.
