Use tips:


1, the kit power supply voltage is DC voltage 5V, try to use a power supply with less clutter and stable output.


2, each time before powering up, all the switches should be popped up, about 2 seconds after powering up before the display.


3, after the display, before installing the shell, adjust the potentiometer so that the voltage between pin 4 and pin 5 of the LM393 is 3.16V.


4, measure what components are rotated to the corresponding gear.


5, measurement of non-polarized capacitance, inductance does not distinguish between positive and negative, frequency and electrolytic capacitors to distinguish between positive and negative contact to determine good.


6, the tail number of the readings are not rounded and fictitious optimization, all the tail number has jumped is normal.
