    Hi
    I am starting a project about microcontrollers. I have problem choosing one.
    My project will measure speed of an object which will pass through to sensors. The two lasers will fall on some LDR or photo transistor and whenever body will pass through it the laser will cutoff and timer will start, now when body reaches second sensor and cut the laser off. it will stop the timer, and calculate speed.
    I want to inquire which microcontroller should i use?

    Basically you need one with a timer. That means almost anything.

    The biggest issue is how the result will get from your device to the human who wants to know the result. This will require the most I/O lines (probably) and maybe the bulk of the code.
