Door Sensor

Former Member
Former Member over 9 years ago

     Hello. I Am a Beginner to intermediate programmer.   

I am trying to build an alarm with a door sensor using a Raspberry Pi and Python 3. I have connected everything that I need, (2 LED's (Green for alarm active and Red for alarm sounding); A buzzer and the Resistors) but what I want is so that one of the LED's is on all the time. When the door is opened there will be a requirement to type in the code through the keyboard connected via USB and if the code is typed correctly then the alarm will deactivate, but if after 10 seconds the code is not entered or that if the code is typed incorrectly the buzzer will go and the Red LED will light up and the Green LED will power off.

      The only problem is is that I do not know how to make the part of the script so that the code has to be entered. Is there anyone that could help with the code?

 

 

 

Thank you in advance.

    Have you considered to get the skills to code in Python? There are many online courses available mostly free. What languages have you done before?

    I have mainly been trying to work on my python skills. I have done a bit of C++ aswell but not that much.

     

    I have written the rest of the code but i can not work out how to write the bit where a type in a code to disable the alarm.

     

    Thanks in advance

    The alarm can be cut by grounding the power to alarm with a transistor. But you have not described your circuits, so this is a guess.
