programing a push button

samcast101

I need to write a program to save energy on my project. the program cosists of a push button connected to pin 1 and a relay connected to pin 2. i need a program that would send a low singal to pin 2(relay) if the push buton hasn't been pushed for 10 minutes. but if the push button is push before the 10 minutes the counter would reset to start 10 minutes again. Can somebody please help me?

You really need to do the work yourself.

An easy thing to do is to set up a loop to check the pushbutton once every 100ms using a PAUSE statement for the timing.
Keep a count of the number of times through the loop. 10 minutes is 6000 x 100ms. Take it from there ...

For the Button Demo it is in the Basic Stamp Editor look in the BS2 Folder

for keep the time use a DS1302 Time Chip that Parallax sells do not for get the crystal

And use the DS1302 Counter Demo Code it below so is the Button Demo

This should get you started
