A good friend of mine told me that he had built a visual feedback for his device tests at work. A few moments later, I wanted my own.

In my work, I work with and maintain GitLab pipelines. Therefore, in the past I created a pipeline that checks all other pipelines and sends a message to a Teams channel with the result of the check. To increase the pressure to fix broken pipelines, I created my own visual feedback for broken pipelines.

To query the status of the pipeline, I call the GitLab API every 30 seconds to get the details of the last pipeline. The LED strip is controlled by Neopixel.
