Being an Electronics student or hobbyist, you may have thought of getting a tester that could test almost anything “THE ELECTRONIC COMPONENTS, OBVIOUSLY!!”

So, Component Tester can test almost everything except the power components, as they consume more of current and power which our micro-controller couldn’t handle !! It automatically detects the component and display its respective values and properties on screen.

  • Resistors
  • Capacitors along with their Equivalent Circuit Resistance Value (ESR)
  • Inductors
  • BJTs
  • FETs — MOSFETs and JFETs
  • Thyristors
  • IGBTs
  • Diodes

Adding to these are much more features to it. It’s has a voltmeter with a range upto 50V DC, a Frequency Counter and Generator. Also you can also detect the IR Codes by simply putting a TSOP Sensor on its test pins…. isn’t that great?

Component Tester also won a prize at Arduino All The Things! Contest hosted by

Currently I’m working on version 2 of Component tester, it will be a much more compact version, maybe a pocket sized version having an OLED Screen to it. Also, it would be portable i.e. with an inbuilt battery embedded into it.

Stay Tuned…!!
