[@ansravlogs]

It worked! Thanks for the tutorial!

[@hpdiyprojects]

Good..

[@architmokal4127]

nice idea

[@ketanpatil4261]

Nice

[@hpdiyprojects]

Thank you

[@pushansarkar8018]

if i connect toy motor in place of buzzer can it run...help please...

[@hpdiyprojects]

Yes only use high ampear Transistor BD139 or BD140

[@binoykumarmahadani8129]

Bhai is project ko party hall room pe buzzer ke jaga koi random song list and lighting ke sath kia ja sakta hay kya?

[@hpdiyprojects]

Bearish aane ka signal ke liye aap buzzer ki jagah aap mp3 module memory card ke sath laga sagte ho or random light ke liye rgb light use kare relay ke sath relay buzzer ki jagah laga do

[@binoykumarmahadani8129]

Kya aap iss project ko banayenge? Please... Iss model ko me aapne naya ghar me use karna chahte hay

[@umairmalik8602]

Why u choosed bc 547 only for this... And is it safe to not use resistor with led ???
Can u explain it
It will became easy for me to understand
Thanks

[@hpdiyprojects]

Use 10k Resistor at base voltage

[@anumandlarakeshreddyanuman8474]

Can you name the rain sensor plate ?

[@manuthplayzyt7000]

nice idea didnt work. i tried without transistor it worked !

[@hpdiyprojects]

I think you make wrong connections
Transistor is for safety and low battery consumption
