Measure the time between two pulses. You can then calculate the frequency.

How are you processing the input signal? You need to convert it to a square wave so that you can use a timer to measure to measure the frequency.

People seem to have more problems with Seeed. I've been very happy with ITead, I've used them three times and haven't had any problems.
19  Products / Arduino Due / Re: Is their a way in the data sheet or some way to add more program memory to due. on: February 27, 2013, 11:40:57 am
The SAM3X chip used in the Due doesn't have an interface for additional program memory.

That's the Library Manager! You need Add Component (F3), see page 12 of the Design Tutorial.
