Easy Circuit Tester

In everyday work, I noticed that most of the time when using a multimeter it takes me to check the contacts, so this project has matured for a very long time, and only today it was done :) Using the tester, you can check not only the contacts, but also the batteries, diodes, transistors, resistors, capacitors and much more (resistors and capacitors up to a certain rating), and you can also check the presence of mains voltage.

*I ordered a printed circuit board only now (2020/03/07) https://jlcpcb.com/ , so I’ll shoot the assembly video after I receive my order.
