Introduction: 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
Step 6: Happy Making
if you have any doubt, please let me know.
