I am looking for a board that will measure how fast the ball was thrown. It’d be like those baseball’s that you throw and the speed is shown how fast you threw it. I’m not really sure as when I researched it most use radar guns but I am doing it a different way.
Also, does sparkfun sell a controller that could control lights based on information from a heart rate sensor ?
Thanks

What “different way” will you use to measure the velocity?
Well I was hoping a board inside the ball could. Similar to how the velocity baseball’s do that you throw and then it says on the ball how fast you threw

In principle, you can use an accelerometer to measure the acceleration, and from that estimate the final velocity.
That would be difficult, because you need to separate the acceleration due to gravity from the acceleration due to the thrower.
Ah yea I kind of thought it might be pretty hard. Thank you for the help

Do you need the velocity over time, or just the terminal velocity?
You could put a switch or contact sensor on the ball to determine the start of the throw, and an internal accelerometer and timer to determine the flight time and calculate the velocity. Detecting the end point should be easy with the accelerometer. If the distance is fixed the velocity will be easy to calculate.
