In this big project video, I basically tried to revolutionize LED lights. That means I wanted to create an awesome led light for my staircase that only reacts when a human passes by and when it is dark. At the beginning everything worked just fine the mechanical mounting as well as the electrical design with uC, LED driver and distance sensor. After the programming and final assembly, everything fell apart. Check it out ;-)
