my question is how to make this a 3 7-segment display and remove the sounds and use only one push button for reset. thanks for your help and sorry for the bad English.
Oh my, that is a challenge. Maybe fashion a pair of stiff stainless steel wires inside a small container with a very low mass stainless steel ball inside (like you might find in a bicycle wheel bearing), so that the ball shorts the contacts together when the container is tilted. Stainless steel tends not to corrode much in an exposed environment, but sealing the container from the environment will limit corrosion over time.
