Edge clock by makit

Açıklama

It all started at the supermarket... I was queuing at the cash register and I saw that they used a piece of plexiglass with edge leds that changed the colour to indicate if the cash register was opened or closed. I liked the effect of the light around the edge of the plexiglass. I seemed to remember that I had a piece of plexiglass lying around at home so, as soon as I got there, I wanted to apply that design to something. As I love electronics, robotics, 3D printing and of course Arduino I thought that I could do some kind of Arduino controlled clock. After that, and some design, test work and code, I came up with this edge clock. I'm aware that at the beginning it might be challenging to tell the time but that is what makes it so much fun when some family or friends come home and ask: What is that???? After I explain it, it’s really quite simple: It uses a common RGB led strip with addressable LEDS (mine in groups of three). It has 12 different groups of LEDS. You can of course change the colour to your liking. Each line of LEDS is one portion of an hour, so 12 different lines, each one is 5 minutes (except the first one that is o’clock). In addition, the line in different colour tells the hour. So, imagine line 0, 1, 2 and 3 are on in one colour (white for example) and line 5 is light in green. That means is 5:15, 5 hours because of green line and 5 minutes of each white line add up to 15 min. If you still have doubts check this video! After that somewhat long…
