Electronic components sorting machine

What our machine does

Electronic component sorting machine takes a mixed pile of resistors, diodes, and LEDs, and automatically figures out what each one is, measures its value, and drops it into the right box — without a person needing to test each part by hand with a multimeter.

Why we're building it

  • Testing parts one by one by hand is slow and tiring
  • Old or faded parts often can't be read just by looking at them
  • Many good parts get thrown away just because nobody wants to test them
