    Arduino Fencing Scoring Apparatus

    so there is a lot I didn't mention. In regards to the no common ground, I am using the drop/rise in voltage from the pull up/pull down resistors to estimate capacitance. That can give a good idea of what you're hitting. Since capacitance varies based on surface area the lame will have a much larger capacitance than the blade' s bell.And in regards to the synchronization that's why I said networking, I could have probably explained more. One issue that can fix the synchronization is to have the slave machines synchronize time with the master after every master hit check and when a touch is scored record the current time of that hit. That way you would know when each touch landed. Now this is still simplifying the problem. It is really complicated and probably why there are only 3 workin...
