Brighten any room or space with this fully Arduino® compatible, ESP32 controlled BrightDot clock kit.

This designer black edition clock features 60 bright RGB LEDs that reflect against the surface on which you mount the clock, hence telling you what time of day it is.

The SMD RGB LEDs are pre-assembled but the rest of the solder work is up to you! Solder the light blocking pads into place and connect the clock to the ESP32 by using the data cable. Then it's time to pick out a nice spot to hang the clock with the invisible mounting option!

Once you've overcome the choice overload of available hanging spots, you can connect the clock to your wireless network and it will sync automatically with the NTP time server. Afterwards, you will be able to control every animation, colour or setting that is available by using the built-in web page which is accessible with your smartphone or PC. Another choice overload situation! Other cool features include the alarm and the LED auto dim for when its bedtime.

Check out the videos to see some cool time animations that you can display with the BrightDot clock!
