I’m trying to build a dot/display driver with my daughter for a school project and have a VERY basic question I’m unable to find the answer to : /
When we try to connect the led to the breadboard the power rail has spaces between each set of 5 holes. And one of the pins hits that space so we can’t push it onto the board. Can I put two leads in the same hole? I wasn’t quite sure how to interpret the picture which seems to show a jumper over the gap. See pic.
From your picture, it looks like the author has modified a LED bar graph to bend one of the pins sideways and solder it to it’s neighboring pin. That would work, but might make it difficult to plug into a breadboard.
If you didn’t want to modify the bar graphs, you could put them on a somewhere else on your breadboard and run jumper wires to the pins. It would take a bit more work, but make all your parts reusable.
Something like this would work but takes more wires:
