At present I am trying to build fencing scoring apparatus, what we call in the sport simply a 'box'. This is one of my first arduino projects and I am a beginner when it comes to electronics. Programming is more my game.
Anyway at the moment I've got a weapon with a button tip hooked up to the arduino. The way that it is meant to work is that when the button is depressed it breaks the circuit and a light shows indicating a hit. Now I've got this working all very well. However, I am having an issue with the sensitivity of the tip. You see when I depress the tip ever so slightly the digital pin registers this increase as a LOW, thus turning on the light. What I'd like to know if there's a way to get the input to withstand more resistance before it changes to the LOW state. It's quite important as there are rules about all this sort of thing - actually I think its somewhere in the region of 200ohms before it should register.
Cheers in advance,
