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.
This project is inspired by AVR TranistorTester by Markus F.
Here I would like to take a moment to thank PCBWay for sponsoring this build and providing me with their great quality PCBs. I got PCBs in all white soldermask and they look amazing 😍. If your project requires PCB, do check them out. You can get 10 custom PCBs for as low as $5 with a wide range of customization options to chose from. They also offer assembly services for your custom projects for a pretty low price. The delivery service is blazing fast, I got my boards delivered in 4 days from the date of order.
