how can i regulate the applied force of a servo using arduino? i'm going to make the same movement as a small linear actuator (pic related) and i was going to use one of them but they're expensive af

buy a servo with the exact force you need.
or, some kind of switch/spring feedback to say when the applied force required is met. the spring is tuned to the force, the action overcomes the spring to close the switch.

There are feedback servos that will give position data back to your microcontroller. It's positional feedback instead of force, but it might be close enough for your purposes. They cost a bit more than normal hobby servos though.
