Too bad you did not put values on your schematic for the resistors. I am partly colorblind, so color decoding resitor values does not work for me. Please help.
The basic material for the construction of these boxes is RVC plate with thicknesses of 3mm and 5mm. Such material is used for making billboards. It is easily cut with a scalpel and glued with universal glue. Finally, it is coated with self-adhesive colored wallpaper
Sir I making this circuit but display shows Japanese letters nothing shows the frequency ? Sir I check all the wire connection, check the diagram repeatly , program are copied in your link, display replaced by new lcd display but is not work .
Hello, what is the margin of error for very low frequencies?For low frequency, this library will have a large margin of error. For example, it measures 100Hz square wave with 50% error, but there is no problem for high frequencies. The reason for this is not to measure with decimal.
what should be the minimum voltage of the signal whose frequency is to measure. I want to read Microvolt signal frequency, is it possible with arduino?
Sir please make an Arduino LCD 16×2 display duty cycle and frequency meter. Tell the duty cycle from 0 to 100% and display the frequency from 1Hz to 1000KHz.
@@MirkoPavleskiMK Great, if I want to measure the frequency at a higher AC voltage level, do you think it's safer for me to use a voltage divider or a buffer circuit to isolate the higher level signal from the rest of the circuit? Thanks.
Nice electronic project
Right!!

We just love the essence of your projects! My question is: would you make tutorials on how to build your fancy retro boxes?

@@MirkoPavleskiMK Thank you!
I agree a step by step would be great
whats the value of the resistors
I agree with the other comments. Those project boxes are excellent.

Thanks for all your videos could you make video about capacitor and inductance measuring systems
Thanks a lot
Hi sir, what is L100microh sir?? And how to make it or buy it??. And it is posible to make lcd oled sir???
That is 10-100 microHenry inductivity
@@MirkoPavleskiMK it buy or make with wire sir??
@@MirkoPavleskiMK hi sir and it posible to used oled sir??
@@MirkoPavleskiMK and elco 1microf is 1uf with 10v or 16v sir??
And for dioda 1n4148 is dioda zener right?
Excellent video, I have already made the circuit and it works perfectly!
Would there be any way to extend the measurement range?
Best regards!
I think with Arduino Nano, no way

Hi sir it is posible to measure freq on 20-220v sir??
Yes, but with voltage divider
@@MirkoPavleskiMK can u show me how to make the voltage driver sir?? I need it sir🙏🙏🙏

What is the highest voltage level I can apply for it to measure frequency without risk of damaging any component? Thanks
+/- 2.5V vithout voltage divider
