This project uses audio input from a microphone to control the brightness of multiple LED's using Arduino. This is part 1 of 3: connecting the microphone to the Arduino.
You will need a:
-microphone and cable
-9.5mm to 3.5mm adapter.
-3.5mm adapter to wire for Arduino hookup.
Step 1: Step 1: Microphone to 9.5mm Male End
Make sure the microphone has a normal, 9.5mm male end connected to it. This will allow the diaphragm in the microphone to convert sound waves into an electrical current.
Step 2: Step 2: 9.5mm to 3.5mm Adapter
Attach the 9.5mm end of the microphone to a 3.5mm adapter. This will allow the microphone to be attached to wires to plug into the Arduino, allowing the electrical current from the microphone to travel into the Arduino to be read and used as an input.
Step 3: Step 3: 3.5mm to Arduino
Plug the 3.5mm input into a headphone jack that has been removed from some other device. The cables can then be soldered to Arduino-capable cables to be attached. This allows the electrical current to flow smoothly from the microphone into the Arduino and from there can be used to control the brightness of LEDs.
