In this project, I will create a truly amazing and satisfying Home Upgrade. It involves lighting up stairs in a way that it does not blind you during the night and also make it satisfying to watch/use at the same time. This involved using IR distance sensors, ambient light sensors, microcontrollers and an addressable RGBW LED strip. I truly love the result and hope that you might give a project like this a try ;-) Let's get started!
