I referred some resources and found that it can be done by a timer and some parts. Yes i could do that and it would be the same as i do now. AC electric motor working principle. Is this design able to expand to accommodate a seven cs4072 code?

CD4072 – Dual 4-In OR Gate

From the truth table, R-0 and S-0 makes no change to the outputs. This circuit has the CD Chip included and can be used with touch keypad as well. Based on your circuit, I made another version which also include the feature datasueet above and the “disable the keypad when green LED lights” enables again after 5 seconds. At 29 December6: May be an auto-reset feature datsaheet be added? It is the same.

There are datzsheet connectors, D1 through D4. At 19 June The circuit is designed to operate at any voltage between 5 and 15 volts.

Look what happens at the truth table in this situation. At 22 August At 2 September Look the video and read the section “The keypad”. You are welcome to comment for corrections and suggestions on this page.

How to do it? To be more secure, the keypad should be on another remote PCB. The 4 D inputs are the ‘correct’ buttons.

This is exactly the same circuit as the previous one, with the only difference on the reset. It can have as many ‘wrong’ digits as you like, but up to 4 ‘correct’ digits.

I opened a forum thread for you to follow. A nice print-out with some kind of artwork and holes that correspond to the keypad PCB-keys, can mask the keypad and make it more elegance. That was one of my imaginations when i was a kid. Imagine that you sit on your PC desk, you pull the keyboard, the mouse is near by, you xatasheet the button and the computer boots.

This circuit is significantly simpler and equally secure to the previous one. What should I do??? At 14 Novemberdatashfet At 23 August At 28 July7: The keypad could be normal pushbuttons.

Look at the following PCB layout:. The only thing that needs to be changed is the relay.
