Simple Vu Meter Using Arduino

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

• Arduino
• led
• aux cable
• jumper wire
• breadboard

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

download code

Step 6: Happy Making
