Hey guys/girls

I wanted to make a (AFK) fish farm on the console edition of MC. I've tried multiple designs but non of them work. Do they work on MC conslole edition at all? i see people on YT making them en showing them working. but it never seems to work with me.

I made multiple ones with the tripwire. But the bobbing of the pin keeps activating and de-activating de tripwire
please help
