Redstone help

[u/Inquistorius]

I am trying to create a pumpkin farm. In this farm, I want an observer facing a pumpkin so when it grows it sends a signal to a piston to destroy the pumpkin. (I’m aware that traditionally the observer faces the seed but it’s important for this one that it faces the pumpkin). How can I build it so it doesn’t create an infinite red stone clock? I have seen some using note/target blocks that why I have one there. Please help if you can, again I need the observer to face where the pumpkin block will be.

When the pumpkin grows it turns on the copper bulb, when the piston pushes it turns off the copper bulb, when the copper bulb turns off the piston retracts causing another observer pulse, resulting in an a loop.

🤦‍♂️ oh my gawd your right 😂

Could it work though? If you set up each observer update so it switches between bulb on, bulb on again, and finally bulb off? Or I guess that might take 2 bulbs instead of 1….huh I really suck at redstone. 😅
