This project is awesome, and I bet that you want one as well. This is yet the best multimeter I’ve made so far and let me tell you why. Well, first of all, is homemade, and that’s awesome, especially knowing that I’ve designed it myself. But second of all, it is very small but it has a lot of modes. It can measure voltage very precisely. The same for resistance and also capacitance. And if that is not enough, it can also measure inductance which usually is a bit more complicated, but this one does it very well. And on top of that we also have other modes for current measurement, frequency, continuity, pulse generator, diodes and who knows what other modes I could program for future firmware updates.

And on top of that, it also has a space for a Bluetooth module so we could connect it to our smart glasses project and see the measurement in front of our eyes, that’s pretty cool, right? Is very easy to use with both hands and you don't have to place it over a table as you do with common multimeters, that’s very practical. Is rechargeable with a USB connector and it has battery protection and much more. I’m sharing all my files with you and also the code as open source in case that you want to make the same project. So let me show you all the details about this PCB, the code, how it works and make the entire multimeter. This was more than 1 year of work. So guys, let’s get started.
