Hi. Great project! I have similar question. I wish to activate alarm after 30 sec. When motion will be detected or door will be open I wish to not start alarm or do something in first 30sec. Could you tell me what should I change? Thank you!
This is good tutorial. I have only one question: what kind of resistor I have to connect with LED? I tried this circle in https://circuits.io but does not work :( I will try live :)
