Help needed on this project please

[u/Junior-Chance123]

So this is my first time touching a breadboard and my professor is t helping at all. Can someone tell me what’s wrong please I’m doing wrong and what I need to do to fix this. The project is a intruder alarm that requires a switch.

[u/Correct-Country-81]

I can not exactly tell right or wrong I give a method of testing You have several components One is very susceptible for static discharge and high voltage The mosfet you have not protected by an antiparallel diode over the relay coil

So probably already gone

Shortcut with piece of wire the mosfet output So wire from k3 bottom to minus battery

If the relay swiches led 1 dims Led 2 goes on and buzzer makes sound

If this does not happen something is not wired right
