Making a component tester based on the Adafruit CLUE #CLUE
On the Adafruit Forums, Kevin J Walters posts an electrical component tester:
I started a component tester on the Adafruit CLUE last year but moved onto other things and have only just got back to that project to finish it.
It’s more about showing what can be done with minimal (four) external components and an interpreted language like CircuitPython than making an ultra-precise LCR tester. It’s based on the octopus testers (AKA I/V curve tracers) found on some old oscilloscopes using a similar approach within the confines of the 3.3V voltage range. It can be seen on Adafruit CLUE component tester identifying a panoply of components (YouTube) and here’s two screen grabs showing it doing its thing with a 1k resistor.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
