We are working on a project where we need the current clock of the Arduino. We have searched and found out that there is a pin in ATMega that is call CLK0, they said that if we put a wire on this one it will take the clock out, but it doesn’t. This pin doesn’t have anything, it value in the oscilloscope is 0. I also read that it can be done with two arduino together, but how do you connect them and where the clock comes out? If someone could help us we would be very grateful.
Thanks for reading us.
