Magical tweezers which identify unknown capacitance!

Magical tweezers which identify unknown capacitance!

Exceptionally, the device which I made this time is quite useful. This tweezers does not only just pick chip capacitor but also identify capacitance value!!! As we know, chip capacitor does not have any printed digit on it and once it is detached from tape or reel, we never know how much it is. This time I made a "magical tweezers" which identify its capacitance, consisting just of ATtiny10 and several resistors. I put threshold for LED blinking for 0.1 uF and if capacitor is less than that, LED never blink, and I can identify that I can use it as a bypass capacitor!!! It is quite useful for SMT prototyping.

    anyone please help me. can this tweezers test a regular big capacitor and resistor ,i mean non smd because i plan to get cheap one for my school project.. tq
