This is great, Iv made one similar from another post. Could you use two arduinos so the tripwire is outside and the alarm/speaker is inside? Bluetooth or wifi possibly?
its ok i have figured it out!
I have been looking at all the laser tripwires and this is great for my first project, Could you please tell me how to repeat the buzzer for another 5 times please.
