Give me code of this project

[@basavarajsgaddi400]

Sir ji maine same aap ki jaise hi connection kiya hu, magar LED aur Buzzer continue on ho rahi hai, lazzer light start hone me off ho rahi hai

bro you are a living Legend

[@saadinnovativeideas]

Thanks bro 😊

[@danalaniz7314]

Great work! I love the graphics too,

[@saadinnovativeideas]

Bundle of thanks sir ❤️

[@user-gx4eu4ll6h]

Amazing❤

[@user-wn4ry3fv4t]

Sir, I tried but the buzzer never stopped buzzing even after the laser was pointed at it

[@syedabdullahjan]

Amazing 🤩

[@saadinnovativeideas]

Thanks aloooot bro❤️

[@bertyesthergeorge654]

Can you pls add the circuit diagram, procedure and working of circuit. Its for our board project

[@saadinnovativeideas]

I have provided everything in the video

[@rehankhanrk7644]

Is battery ki jaga cell wali battery use ki b sensor k ilwa sb sari chizain work krhi hain

[@saadinnovativeideas]

Voltage 3.7 V honi chahia koi bhi cell use karsakta ho, circuit diagram se compare karlo, solve na hua to ldr change karla

[@asifmohammed8076]

Bro please show me how we fix the switch

[@saadinnovativeideas]

Cut one wire of the battery and solder the switch

[@Al-Sani]

What is name of transistor

[@saadinnovativeideas]

TIP-122 Transistor

[@RajeshSharma-vz3ci]

I have made everything but my laser light is not striking the mirror correctly. Kabhi ek par jati hai to dusre par nahi. Please help.

[@saadinnovativeideas]

Thora Bara size ke mirror pieces lelo phir asani se strike karaga

[@fjxgy_8748]

The 3.7 V li-ion where can I buy it from

[@saadinnovativeideas]

From any electronic store.. you can use any phone removable battery

[@dianaapriatin3378]

Why does mine make a continuous sound when it hits the light and when it hits the light it doesn't make a sound, that's why, si

[@saadinnovativeideas]

When light strikes LDR the buzzer doesn’t make sound, when light is interrupted (by an object supposed to be theif) it should sound, because Light Dependent Resister provide resistance when ther is light…

[@rehankhanrk7644]

Humara sensor work nh karha plzz koi guidelines de or alternat banatii isla

[@saadinnovativeideas]

LDR me masla nahi hoga, app ne konsa or components use ki hai?, circuit diagram dekhe bilkil usi ke mutabiq karla

[@saadinnovativeideas]

Transister ke pinout (collector, base, emmiter) ka khayal rkha

[@rehankhanrk7644]

Sara circuit humne breadboard py bana ya h
Kiya breadboard py bana k Liye high ya phr low k components chaiye hote hain ? Apne Jo use kiye hain ussi sy ban jai ga breadboard py ? Plzz jldii bata dain Monday ko project submit krwani h deadline h plzzz

[@rehankhanrk7644]

​@@saadinnovativeideas
Humne wohii components use kiye hain Jo apne discription box main diye hain but difference srf itna h humne breadboard use kiya h sari fitting breadboard py kii h ?

[@saadinnovativeideas]

@@rehankhanrk7644 G breadboard py bilkul ban jaiga. Me ne bhi sb se pehla testing breadboard py kia tha

So what?

Code of this project

[@saadinnovativeideas]

No code required

​@@saadinnovativeideasok thanks for reply

[@theillogical76]

But thief can see the red laser dot on reflector in dark,so it would be better to use infrared laser if exist 😅

[@saadinnovativeideas]

Yeah thats great idea but then it would not be visible to LDR I have to do a lot more modifications and I may do..

[@theillogical76]

@@saadinnovativeideas you can use infrared receiver

[@saadinnovativeideas]

Yeah in the upcoming one
