  • OBSOLETE! The nice display is discontinued. Any direct replacements??

  • hi…if I have 3 common anode displays, can I replace the semented display?

  • I also swapped out the greenish led for a much brighter white one. The tiny green light that comes with the button was quite dim.

  • I made it! There is one small error on the picture of the wiring. The pin description for the signal to the digital readout says pin 2. That is correct. However, The picture shows the wire on pin 3. oops.
    This was a great project. I ordered all the parts from the website, and they arrived quickly and in good shape. The red box is a nice touch. It is easy to carve with a dremel. The digital readout is bright and clear. I used an arduino Uno model board for mine. I will be taking it to work to see who is the quickest. Thanks for the project !

  • A (Fritzing) diagram would be very helpful; I can’t get the images large enough to clearly see the wiring connections. Thanks for this tutorial.
