I used Autodesk Eagle to design the circuit board for the project. You will find schematics and design files in files section. Alternatively, you can also go to PCBWay (redirects you to the project ordering page) to directly order your high-quality boards.

⚠️ Always remember - "If it smells like chicken you're doing it wrong" ⚠️

To begin with soldering I started out by soldering the resistors and capacitors first followed by the button and transistor. Followed by the 4mm banana jack binding post and male headers. Following the above mini-steps while soldering will make it easier for a neat looking board without lose or hanging components.

Follow the instructions in the video to upload the firmware. The code is available at Project's GitHub repository.

Commands -

make all

make flash

• Hook up any component of your choice to the test leads. 
• Connect UNO to PC 
• Open Serial Monitor in Arduino IDE 
• Baud Rate - 115200 bauds
• Press the TEST button on the board

You'll see the test results popping up on your Serial Monitor :)

Wooohoooooo!!

You've made your own DIY Arduino UNO compatible Component Tester 🎉🎉🎉
