Introduction: Arduino Volume Controller

By

Today, I am going to make a Arduino volume controller. This product can make people be quiet or notice their volume are too loud while they have to be quiet. This product can be used in everywhere, such as your bedroom, office and places where people are talking.

Supplies

With this project, yYou have to prepare:

- Arduino Nano x 1

- Green 5V LED x 1

- Red 5V LED x 1

- 560 Ohm resistors x 2

- Jumper wires (male to male) x 4

- Breadboard x 1

- Electret microphone with MAX 4466 amplifier x 1

- USB to USB Mini B cable x 1

- USB Power Bank or 5V Power supply x 1

Step 1: Construct the Circuit

For supplying some power to Arduino, I connected the Mini USB port on the Arduino board to a USB power bank.

Step 2: Write the Code for Your Product to Work

You can have a go at writing your own code or copy the example upstairs.

Step 3: Tune the Volume

Step 4: Last, Connect Your Breadboard to Your Computer

And it's done!!!!
