How to Make a Shirt With Heartbeat-like Flashing Lights Using a CPX

This shirt is very unique to other clothing you might have worn in your life. There is a Circuit Playground Express which flashes to the rhythm of a heartbeat. It is very simple and perfect for new coders and fashion designers.

Supplies

You will need a shirt that you are willing to sacrifice for this build

A laptop to create the code (go on the URL link shown in the photo)

A circuit playground express

A small battery pack

Step 1: Brightness

First set the brightness to 130 to make the lights pop but not enough to blind someone. This will make your work stand out more when wearing it.

Step 2: Flashing Lights

Go into the code maker (block code) and copy down this code. This part will make sure to make the lights flash in the way of a heartbeat. There is also a faint sound whenever the light flashes.

Step 3: Putting on Shirt.

Next, you will sew the CPX onto the shirt. I found it easier to sew it onto a small piece of fabric and sew that on but there is not really a benefit unless you don't have a chest pocket on your shirt to put the battery pack in it.
