Father’s Day 2018 has come and gone, but it’s never too early to start planning for next year. As seen here, Michael Teeuw decided to build a clock out of three analog voltmeters for his dad in 2017. After getting sidetracked last year, he was finally able to complete it on time for 2018!
Teeuw’s clock features a trio of indicators, properly scaled and labeled for hours, minutes, and seconds, with control via an Arduino Nano, along with an RTC module for accurate timekeeping. Each indicator is housed in its own 3D-printed module, with white LEDs added for visibility.
If you’d like to build your own, Teeuw’s code is available on GitHub and the 3D print files can be found on Thingiverse.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
