CircuitPython 7-Segment Character Clock #CircuitPython #Feather #Adafruit @Adafruit @_ohm51 @HackadayIO

Via Hackaday.io, Alex Padilla has built a cute free-form clock using Adafruit parts.

I was inspired by Mohit Bhoite’s electronic sculpture projects, particularly this one featuring a 7-segment display.  I don’t have that caliber of soldering or programming skills, but Adafruit’s CircuitPython looked like a good way to quickly program a small project and the ItsyBitsy M0 Express had capacitive touch capability to easily provide inputs.  I used the RTC+SD Featherwing as the middle layer between the ItsyBitsy and the 7-segment display because it has a double row of headers and the inner set of headers just happened to match the width of the headers on the ItsyBitsy M0.  I made 1:1 scale drawings of the boards to plan the bends in the brass rods, and actually used the lines on the page to get the bends to the correct angle to hold up the 7-segment display.

The build came together almost exactly how I envisioned it.  After I started testing the display I found that the LED segments were hard to see, so I put a sheet of dark acrylic in front to cut the glare.

The build used many Adafruit parts:

See the video below for the clock in action and read more on Hackaday.io. Great build!


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.
