Hi Raj, sorry for the delay in reply. Depending on the size of your house you will have to update the angle of rotation of the servo in the code to suit your house size and rotation.
Did you mean the servo keeps rotating non stop?
Hi, all the parts I used was bought from Robotshop.com. There you will see all the specifications and more details of each component. NB: any Arduino PH meter will work.

sorry I've been away for a while working on something.normally check if all doors closed tightly cause with little opening, that an open-circuit hence it cant be activated. turn system and check everything is sealed tight then power it back on. hope that helps. cheers!
1. Did you use a potentiometer for the LCD? if yes, adjusting it can help the display to project.2. Try making the connection to the arduino using power cable to wall socket instead of USB to computer. give it a shot and let me know
Hopefully you could, give it a try and let’s see how it goes.
Yh the motor will rotate but since the model u built may not be exactly the same size as mine the servo will not get the exact position right unless u update the code. If you go through the code carefully u will see where that servo code is and the position I set was, 65, 145, 10 etc. This can be changed depending on how you want it but try playing with it and test it till u get the right angle needed. Thnks
Ok am here to help, jus let me know what kind help you need. thnks
Most problem with display has to do with either the connection of the potentiometer. Try to reconnect again and be mindful of the keypad Row and column to the Arduino pins. Adjust the potentiometer to reduce brightness if need be. Hit me up if it works. Cheers
Connection to Arduino or the potentiometer I meant..thnks
Yes pls u can
NB: you will need to download all the libraries I've indicated in the code either with the site i provided or others. Cheers!
yeah you right, I'll update this project in a while with other more features and include the Doppler radar and upload an operational video. cheers!

hi, I have redrawn a much simpler circuit u can try on a breadboard and it works great. Just follow each connection as shown accurately . For the function of each component, all the resistors act to reduce current and lower the voltage levels to each component for it to have exactly the right amount of current or voltage it needs to work with. The transistors are amplifiers, it amplifiers the noise received and can also act as switching between the signals by its operation.LEDs lightBattery gives powerCapacitors acts as filter, and also blocks dc voltage.Hope that's helps..
