Not sure but I read that pulseIn you have to disable interrupts for a accurate reading, for pulseInLong no

Nice project, but what can it be used for?

[leonardmiller]

question what is the point of this thing what settings are you potentiometre set to and for what e.g. a nominal car water temp reading for ecu is set to say 400-900 ohms an air temp has a reading of 500-1250 ohms and then O2 sensor has other reading in your set up how would you corrolate all of thse together woulf you build 3 of these to feed into the ecu or just one. When i did this years ago all i needed was 3 variable potentiometres set them all to the nominal cold resistance reading then very them from there as the engine warmed up it cost a whole $5 instead of $175 each for the prospective origonal switches, is your set up any better than what i was using ??

What is the generator and what kind of wave does it generate?

[kmhooibg]

Hi, I'm interested on that. But may I know how to test crystal oscillator with it?

[hendritresnahadi]

Why the frequency that we've been measure off allways moving? Tx u sir or anybody 🙏

[michaeljoshuamanallo]

What is the max frequency that it can count??

[botak]

Hi sir it is osible to check frekuensi untik 100khz - 150khz??

[RAUF.Y]

Sir you are great plz make more project on ardiuno
Like mppt solar charge controlar
Solar tracking system etc

[vengug]

Sir how to measure ac 230v line frequency and voltage please help us Thanku

[yashdasputre]

Hello sir, can we connect the multimeter to the bread board ?

[HuyNguyen-rmkp]

can i change input pin D9 with another pin

[sureshmosquito]

hello friend, I like your video
can i suggest?

Can you make an audio amplifier using Arduino that can change the frequency depending on what frequency you desire using a potentiometer and can be shown on the LCD?
thank you

[badalsamanta]

I can measurements ac 220 volt frequency & pwm frequency in smps.

[daveh]

i need a frequency counter from 0 - 120 KHZ...how difficult would it be for me to programme one of these arduino as a novice ????

[jualanled]

how to create at assembly code of 8051 ? thanks sir

[pranavramesh]

what is the max frequency that you can measure with this?

[thescience]

Is there any way I can make such frequency meter to work at high voltage (about 10kV)???

[G-R--L-E-M]

Can we use it to measure frequency in PWM circuit?

[yasimmehmood]

Excellent Hi dear sir I already subscribed your channel please tell me maximum frequency measure kHz or mhz
