Step 1: Materials Needed:

1. 3.5mm TRRS Audio Jack

2. 39k Resistor

3. Tactile Button

4. Audio Jack enclosure(Optional)

Step 2: Circuit

First of all solder 39K Resistor parallel with button as shown in image. If you have long button legs, then cut the legs of resistor after soldering or solder the resistor bending over terminals of button and solder the terminals of resistor.

Step 3: Audio Jack

The Audio Jack has four terminals

1. Left

2. Right

3. Mic

4. Ground

We have to connect the circuit made in previous step to Ground and mic as shown in Diagram.

Step 4: Enclose It

Enclose the circuit in the enclosure of audio jack and now it is ready to use.

Step 5: App

You can use any app available on play store. But I found "mSwitch" very useful. I would recommend to use it. Now assign the function of clicks and it would be ready to use.
