Inductance test table developed based on arduino

This is an inductance meter based on Arduino design, made with atmega328p. The main voltage comparator is very important, so be sure to buy a genuine one. Here is the introduction:

• "LC" - Period of internal inductor + internal capacitor oscillator (in timer units, 1/16 microsecond)
• "LCC" - period of internal inductor + internal capacitor + calibrated capacitor oscillator
• "CAP" - internal capacitance value, uF
• "IND" - Period of internal inductance + external inductance + internal capacitor.
• Short-circuiting the detection port is correction;

The LCC period should be larger than the LC period. The IND period should also be more important than the LC period. The following is about using arduino UNO as a programmer to program atmega328p Boot loader; 1.

Material preparation Arduino UNO control board 1 piece of 100 ohm resistor 1 piece of 22p capacitor 2 pieces of 16M Hz crystal oscillator 1 piece of ATMEGA328P package chip 1 piece of breadboard and several connecting wires 3. Wiring diagram ( Note: The resistor connected between the reset port and 5V must be about 110Ω, and the reset port does not need to be connected)

4. Open ARDUINO IDE, click File/Example/ArduinoISP in the menu, and upload the program to the Arduino UNO control board. 5. Then, click BOOT LOADER. If normal, write BOOT LOADER to 328P through UNO. 6. Use UNO as a burner to write the sample program. One thing that needs to be explained is that do not directly upload the program to UNO. You must press the SHIFT key before clicking the upload button.
