Need a simple, low cost way to display digits using your Arduino? Look no further than the Digit Shield now available in the Maker Shed! This easy to assemble shield uses a bright green 4 digit, 7 segment display to give you the data you need. Use it to make clocks, timers, display sensor data, or anything else you can dream up for your next project!

  • Easy-to-use open source library makes it very simple to display integers and floating point numbers.
  • Multiplexing of digits is implemented using a timer overflow interrupt handler for flicker-free display.
  • Only uses 4 Arduino pins (2,3,4,5).
  • All through-hole parts for easy kit assembly.
  • Cool, crisp, green display.
  • (Arduino not included)

Also, be sure to stop by the Maker Shed to see our newly refreshed site!

I am the Evangelist for the Maker Shed. It seems that there is no limit to my making interests. I’m a tinkerer at heart and have a passion for solving problems and figuring out how things work. When not working for Make I can be found falling off my unicycle, running in adverse weather conditions, skiing down the nearest hill, restoring vintage motorcycles, or working on my car.

    “Use it to make a clocks” …does it have a colon? doesn’t look like it. (“colon? we don’t need no steeeking colons”)

  • Michael Castor

    Good catch! I had an unnecessary ‘a’ in there. Should read better now!

      I didn’t even see the syntax problem. i was blathering about the electronic device, clocks (west of Germany) often have a (flashing) colon between the second and third digit to separate hours from minutes. this device has no capacity to make such a colon (that i can see) therefore its general usefulness for making classical appearing digital clocks suffers to some degree.

    If there’s a decimal point between the first two digits and the last two digits, that may make an acceptable substitute for a colon.

    Ages ago, I had an IBM PS/2 model 9595, which has an information panel display (6 LED digits). It was pretty easy to write a program that would turn that into a clock. :-)
