In my past component tester projects - Component Tester in a keychain and USB Component Tester I received many comments and messages asking for an Arduino compatible version of the component tester. The wait is over folks !!!

Presenting Component Tester UNO Shield...?? 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.
