Goal of this project is to make unique and artistic wearable device for every day carry.
Information is dispalyed on custom 16×16 monochromatic led matrix made out of 0603 leds. Device can be programmed form Arduino IDE through built in micro USB. Micro USB is also used to charge lithium-polymer battery of 300mAh. With 300mAh battery and daily active time of 30min autonomy of 10 days should be possible. There are also RTC chip with alarm function, accelerometer, ambient light sensor, piezo transducer and hall effect switches to replace mechanical switches. Small neodymium magnet on the side of the watch is used to activate hall switches and emulates the look of “Crown” of mechanical watches.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to.

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.
