A description of my Alarm clock with dawn simulator for the Fallout event organised By Hackclub

AND see just how beautiful it is !!! Yeah I know I did a great job you can tell me ^^

And to see how it works in details you can watch the video that I did on my alarm clock : (CLICK ON MY AWESOME FACE !)

I really can't wait to build my project, develop my skills and learn so much! I'm gonna give the best version of myself to be proud of my alarm clocks and I also hope that I will have the chance to go to Shenzen to meet other hardware fans! Kind regards, your French friend, Florian "Carabouille" CHARLES :))
