2k ohm ka rasistor chalega?

[@harshdhiman7thclass977]

Bhai Mera bhi lager daalne par of nahi ho rha hai

[@twelvesidegamerviraj7315]

Mera bhi kya kare

[@eyobzene8011]

from where did you find bc 547 and ldr

Bro Mane bhee same project bnaya but jab led par light padti hai tab bhee thodi thodi beep ki awaz ati hai

hlo Bhai
aapka toh light padne ke baad of hota hai par mera toh light padne par on hota hai
pls solution btao pls

[@suryamechanism]

Bro तुम्हारा laser light को अच्छे से cover करो, जैसे laser light को छोड़के और कोई भी लाइट आना नहीं चहिए
Then if any problem found then you may not focus the laser correctly on LDR
or your circuit may be wrong

[@sa.hilll_]

22k resistance chalega

[@suryamechanism]

नहीं बहत ज्यादा हो जायेगा ।
2 ohm के आस पास लगा सकते हो
