Building a digital clock with older Arduino parts: Time Cuboid #Arduino

chebe found the need for a desk clock and looked to build one from the parts on hand.

I didn’t want to go buying lots of unnecessary things, or wait until my usual suppliers were back in full swing. So I dug around in the piles of boxes that comprise my electronics stash. Back at GaelHack (seven years ago) I started on a clock, but it never left the breadboard. I dusted that off, and found most of what else I needed.

This included:

  • Arduino Duemilanove 328
  • LoLshield with blue LEDs
  • An Arduino Proto Shield with a few parts on it
  • SparkFun Real Time Clock Module

For the clock face I dug out an Adafruit Perma Proto breadboard PCB, quarter size (Adafruit / Pimoroni), and the 0.56″ 4-Digit 7-Segment Display w/I2C Backpack – Blue (Adafruit / Pimoroni) from seven years ago. Mostly I’m using the Proto board for getting the display at the correct height. I made my own ‘jumper cables’ with solid core wire, to minimise the space needed to fit it all in.

The project was placed in a semi-transparent cube (shown above). Time Cuboid

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, 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.
