High Frequency Measurement

hello everyone.

im yoga from indonesia and currently working on my final project. im making an oscilloscope using arduino and processing. but i've no idea how to measure the frequency input (up to 360KHz). is there any way to measure the frequency using arduino?

i tried to use frequency to analog converter (LM 2907) but it worked only up to 2.5KHz.

i really apreciate for any help from you guys

thank you so much.
