Make a 7-Segment Display with the Crumble

Here is our latest Crumble project, hot off the press!

Once again it all started with an idea. We wanted a better way of displaying numbers (and some letters) with the Crumble – and that got us thinking. In essence a 7-segment display is made of seven bars, which get lit up. So we decided to give it a go.

We started out with all of our resources. Along with this we used a glue gun and a pen.

After cutting out our templates, we stuck down borders around each segment and the whole display.

This is the basic ‘shell’ of the 7-segment display. It just needs Sparkles, and a paper covering to diffuse the light.

We then wired up the display, Starting with 0 at the top and working in an anti-clockwise spiral shape, connected them all together, gluing a card support to hold the Sparkles in place.

After wiring it up, connecting to the Crumble and programming it, we have our very own 9 second timer – using real numbers!
