I every body. I have a noise problem with my arduino. when I apply 5V to digital pin 2, the next pin digital pin 3 receive a hickup signal that disturbs me a lot bcs I need to use pin 3 to do other stuff.
I tried to change position of the arduino in the breadbord severla time in case there was a short circuit Inside.
Suggestion? :o
Hi
Please post a diagram of how your Nano and other hardware is connected. A photo of a hand-drawn diagram is ok.
And please post your program that shows the problem happening. Use code tags (the </> button on the toolbar above the reply window).

I just have the arduino connect with the computer by the miniusb cable and I connect pin 5V to digital pin 2.
No code, I am measuring the noise with the oscilloscope.
Connect 5V to pin 2 via 1k resistor. It will reduce noise.
Thank you!
A lot of noise went away XD
