Is that right?

Much better, still to remove the connection from c1 to pin2 of your 74HC14.
c1 is just between 5V and GND and intended to be parallel (and close to) to the power pins of the 74HC14 

"Software" is fine so far, IMU ( description is not as detailed as your circuit picture )

No need to have that buffer there.

Hi all!
I'm new bie. Hope everyone help!
I'm using Arduino Nano v3.0 Board (ATM328P).
+ I use one potentiometer. It uses the reference source AREF
+ Frequency_Board uses +5V source on board.
I'm afraid that USB power is not enough to provide in my application
I hope everyone to explaine my problem.
Thank all!



You are fine. That circuit looks like it only uses a 10 to 20 milliamps. USB will give you 500 mA.

I'll bet he's using that HC14 to sharpen up the detector output.

That circuit still has the buffer output connected to 5V
