1. I have questions regarding this circut. I am building a keypad to open a gate but I was wondering if I could make it a four key code instead of seven.
2. How do you change the order of the pins so I could make a different code?
3. Also wondering how the chip works, can you punch in any number that is hooked to the chip code and not reset it or does it work that way. If you dont hit 2,3,4,6,8,9 of resets will it still reset if you dont punch the code in, in order as shown on the website. (1704570)
One more thing, bogdanfirst, thank you very much for the website you have given us, its a big help!
-sorry for all the questions- haha
