I am try to make Simple Pulse Counter using arduino uno board, so i find following link [image] library.io where write "Simple circuit that counts pulses, and reports it through the serial monitor. This circuit counts pulses fed into pin 12. In this circuit, t…

What is connected to pin 12 ? How is the input wired ? Do you have a pulldown resistor in place ?

I am connect wire diagram See the image And I am use 1k Resistor [thumbnail20161210-31527-14y0906.png]

Those tactile buttons have a switched and non switched connections. Connect the Arduino to diagonally opposed corners of the button rather than along one edge as your diagram shows. You will be guaranteed to pick up the switch legs. [7a7829decdd4b936e8ceb34da15c3dc5237bad91.png]

Hello, Thanks for your help, now its working perfect. Thank you so much.
