මචන්ලා උබල දන්නවද අර music beat එකට පත්තු වෙන led එක හදන්න.කෙලින්ම speker එකට දුන්නහම වැඩේ හරි එත එකට වෙනම circuit එකක් තියනවා.දන්නා කෙනෙක් මට කියල දෙනවද

vu meter kiyala google karaPAN,

Machan LM-3914 kiyala 18pin IC ekak thiyenaya. anna e IC eka use karala design karapu circuit internet eke thiyenawa. LM-3914 IC eka DOT MODE and BAR MODE kiyana krama dekatama weda karanawa. oya hoyanne DOT MODE eka wenna ethi. Google image search ekak daala balanna IC eke no. eka daala. me IC eka colombo wala Rs. 175k wenawa. pita palath wala nam danne nehe.

me wage ekak,R2 ekata siganl eka denna tiyenne(circuit eke wage grnd karanna epa),man oya net eken gatte,R1 & 12V voltage eka one vidiyata wens kara ganin(3V denwanm R1=220Ohm wage...etc)
