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.

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

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.

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.

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.
