# Input Devices

I decided to make a device that allows you to track your happiness throughout the day. You can spin your happiness via potentiometer and see instant feedback via LED for the value that you would report

After this, you can press the capacitive touch button for the esp32 to post your happiness value to the webserver via Wifi.

First we create the custom footprint for the potentiometer.

We then finalize the PCB. We use a very wide trace for the capacitive touch button ![](../assets/week7/2.jpg)

We mill. ![](../assets/week7/3.jpg)

We sand and solder this beautiful pcb. ![](../assets/week7/4.jpg)

We can see the board in action!
