If its a small red module from a dollar store laser pointer, you can use a small MOSFET and an Arduino no problem.I need to make my laser soured (low energy red is; even a laser pointer) to pulsate (completely on, and off) 250 Hz or more. I have no idea what kind of equipments would help me to do so?
Do you think only pulsating the power source using a controller (or anything cheap that can do it) would produce accurate results?
Thanks!
