    I am doing a project that involves detecting an arrow shot from a bow over 2 photo transistors. I was looking for ideas on monitoring the current under normal conditions, and checking for a change, when the arrow passes over it. Any help is appreciated. Thanks

    I have no knowledge of archery.

    To determine the requirements for a system as you suggest, could you say what the speed of the arrow is?

    The speed of the arrow will be around 250-300 feet per second. I am using L14G2 phototransistors which I purchased from a company that makes the entire system. The actual circuitry though was not available.

    Thanks. I'll put my thinking cap on!
