Please can you show us how to make the buzzer to keep on buzzing so that it can wake us up and we can reset the alarm? At the moment we will not hear one quick beep and the intruder will wake us up. please can you make this modification thanks
I've made the same circuit but its not working properly when I throw laser light on it it does not stop buzzing... I've checked the circuit many times it's all according to your given diagram..
@@nouredeen4720 please mine is not working…I used 547 and it not working…I think my error is the soldering Please I need video of the soldering help please
Thanks for your video.it's really works and I have made one.

Super g
Which ohm resistor you are using
Amazing
what have u used to attach batt connector
What is the unit and capacity of resistance and ransistar
Please send
Plz iska ak circuit diagram bna skte hai aap
Circuit diagram khotoy? Transistor number or Resistance number ki acha
check description "KHOTOY"
awsome
Can we off the alarm from outside without touching the laser

Check polarity of components and no. of transistor
+Technical Nisar now ive used a resistor of 200ohm at the base of 548 its working great thanks
Sajjad Khan Fazli i used 200 ohm but its not
