It contains two sections of 54 LED’s each, one for the top and the other for the bottom. It runs off 12V DC and draws about 1.2A. I found that an exposure time of three minutes gives good results. Keep in mind that UV light is extremely bad for your eyes and you should always take the necessary precautions operating equipment like this. In order to avoid unnecessary exposure to harmful UV rays, I added a micro switch in the lid that will switch the light source off when the lid is lifted.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
