LED brightness with an Arduino! Im working on a better pulse width modulation video, but it's a challenge to make it only a minute long! I'll try my best to finish it soon! If you guys have recommendations on what I can teach or make next, I'd love to know! I had a whole list of electrical engineering and electronics topics but I lost it! Some people asked me to teach math or coding but let me know if you're interested in that! I still need to teach more Arduino! Maybe I could make a whole teach
