After some my Arduino project remains unclaimed touchscreen, so I decided to realize my chidhood dream to create a chess program. After a couple of months it wins me, but it is not big deal because i do not have any chess rating, just amateur.
I made this LED pendant light from plywood, LED strips, and flexible LED channel. Since I designed this for my living room, the music syncing had to be incognito. With this in mind, I used warm white / cool white / amber LED strips, instead of RGB strips.

This project can be useful for you if you have a website that you can use to keep the data. The common way is to set the ESP8266 to server mode and connect to it from the internet by entering your router IP address in a browser. My internet provider don\'t let me do that by changing my IP address each time I enter the IP address.
LIDAR (Light Detection and Ranging) is an optical remote sensing system which can measure the distance of a target by illuminating it with light. LIDAR technology is being used in Robotics for the perception of the environment as well as object classification.
