Security system with arduino uno, pir sensor, rfid, lcd, buzzer and leds


How I says in the title I want a make a security system but I dont know how because I’m new. I want to make a motion sensor pir and to alarm me when someone pass and stop alarm with the rfid card, and with lcd.

Please someone can help me with the scheme and with the code.

Thanks for understanding !!!!

Start simply.
Look for examples of what you want the different parts to do in the IDE.
The LCD and RFID libraries will show you how to display messages and read tags.
The PIR will probably just look like a switch.

Don't try to get it all working in one go.
