| Re: measuring baseball bat speed well, it's quite tricky. if u use 2 IR sensors amd u know the distance between them, it could work the ideea is to use the seosors, conect them to a stopwatch(a digital one) to the start and stop buttons and have the time. u can use the distance batween the sensors so that the watch will show the result in km/h or m/h any way, good luck | |
