LED VU METER
This is a cool LED project I am undertaking. The heart of this project is using the LM3915N (or similar) LED driver. Once completed this can be connected to your sound card or can be connected via a 3.5mm jack for some really cool effects to light up your room. I connected this via 2x4.5v rechargeable battery.
Lets 1st get to know more about this cool projects,that what exactly is this vu meter and how does it works.
DESCRIPTION:We can consider the Volume Meter as an Equalizer, which is present in the Music systems. In which we can see the dancing of lights (LEDs) according to the music, if the music is loud, equalizer reaches to its peak and in low music it remains Low. We have built a Volume Meter or VU meter, with the help of LM3915, which glows the LEDs as per strength of the sound, if sound is low, lesser LEDs will glow, and if sound is High more LEDs will glow, check the Video at the end ,I will provide you the link. VU meter also serves as a volume measurement device.
COMPONENTS REQUIRED:
1. 20LED'S(red,blue,green,yellow)
2. LM3915 IC
3.10K pot
4.1k resistor
5. Power supply 5v or 9v(battery)
PIN CONFIGUARATION(LM3915):
CIRCUIT DIADRAM:
AFTER COMPLETION:
So you're done making your own music reactive color changing lights! Now you just have to connect it to an audio device, play some good music and watch the lights glowing in the dark changing their colors with every beat.Your friends would surely be jealous with such a cool thing!
This makes the end of this post. Hope you liked it. Please share if you think it was awesome. Don't forget to follow for more cool projects!
