Laser break detection for high speed passing
So, I'm working on this project where a laser and a photoresistor are connected to an Arduino. The goal is when a 2inch board swings through, it breaks the laser beam, which triggers an LED to light up. The challenge is that the board is going to be traveling at 30-50mph.
Is a photoresistor able to detect the break in that quick of a moment? Does anyone have a better idea on what to use that will work better in detecting the 2inch board passing through?
