LM3914 is linear led meter LM3915 is logarithmic led meter LM3916 is a true VU led meter for displaying a representation of the signal level in audio equipment, each led stand for a dB level.
Mere vu metar ke connection Galt jod gaye the audio input wire mai mene Plus de diya tha battery ka jisse khraab ho gaya kya kare ic kharab hoa ya kuch or please reply
Bhai kuch jankaari leni thi k jaise 1000 watt amp me vu meter lagane k liye supply 24 volt ki jayegi ya 12 volt ki ur agr 24 volt se b jayegi to wo 24 volt hum oaha se lenge alag se trnsformer lagaye ta power stage se supply de poori jaankaari de bhai ur us pe ek vedio b banye jis se hum logo ko achi jaankaari mil sake
Maine 3915 ic se banaya. Magar audio k hisab se Nehi chal raha hay. Agar potentiometer ghuma raha hay to sab led on ho ja raha hay. Solution bataye please.
@@tchMri sir mane isko aap ki video ko dekhkar banaya par ye work to kar raha hai par bess or speker ki volium nahi aa rahi hai to sir koi soluation batao naa please
Sir while you showing in parctical of this vu-meter ... few connection is different from given circuit diagram... So ,i want to known that if i do this circuit that what are you doing it will be correct or not ?
Very well explained, please upload a video with more led for DIY UV meter
Nice,,and excellent video bro
