This is a fairly complicated project but so much to learn here - -from soldering to perfboard, to button placement, to Arduino programming and beyond. If you or your students are looking for something a bit more complicated than the typical Arduino weather station, this could be just the thing! — Douglas
We’ve all got calculators on our phones, in our web browsers, and even in the home “assistant” that’s listening in on your conversations all day on the off chance you blurt out a math question is can solve for you. The most hardcore among us might even still have a real calculator kicking around. So in that light, building your own DIY calculator might not seem too exciting. But we can’t deny this Arduino calculator project by [Danko Bertović] would look good sitting on the bench.
In the video after the break, [Danko] walks us through the creation of the calculator, from placing all the through-hole components to writing the code that pulls it all together. Special attention is given to explaining the wiring, making this is a good project for those just getting started on their digital hacking journey. It also helps that the whole thing is put together on perfboard with jumper wires; no PCB fabrication required for this one.
