Component Tester - UNO Shield
Presenting Component Tester UNO Shield...š„ Similar functionality as of USB Component Tester, with all through-hole components and a little button to trigger the test from the board itself. It gives you the flexibility to upload the code via standard Arduino UNO USB cable. So, you don't need to re-flash the bootloader. Though Arduino's bootloader limits some of the functionalities and capabilities, still, I would argue it is a great addon to anyone wanting to convert their Arduino UNO in a Component Tester.
This project is inspired by AVR TranistorTester by Markus F.
