Electronic timer with multiple photoelectric sensors

I am a science teacher and am interested in building a timer utilizing photoelectric sensors to start the timer and record 4 times as the the remaining four sensors are tripped. The 4 recorded times could either be displayed on a screen or written to a downloadable file to an application like Excel.

First, is this something doable with the Arduino board? Second, would someone with little programming experience but a lot of motivation (me) be able to figure it out? :grin:

Thanks for any responses!

Simply yes, and without even the hint of a shadow of a doubt, yes. And there's heaps of advice on these forums for when you get stuck of course.

What events will trigger your sensors? Geoff

Its not exactly what you want, but its close -
