Simple Vu Meter Using Arduino

Introduction: Simple Vu Meter Using Arduino

About: I am an electronics hobbyist and I love to share my works with others

A volume unit (VU) meter or standard volume indicator (SVI) is a device displaying a representation of the signal level in audio equipment.so in this tutorial lets build a VU meter using Arduino

Step 1: Things Needed

Step 2: Circuit Diagram

just add an aux cable to pin a0

Step 3: Connections

connect anodes of less to pin 2-13

connect cathodes together and connect to ground

connect aux cable a0 and ground

Step 4: SOLDERING ON a DOT PCB

arrange in a round shape and solder

Step 5: Code

Step 6: Happy Making

if you have any doubt, please let me know.
