Complete tutorial :-
This video is about how to make simple Arduino based Tachometer.
Watch full video for step by step tutorial to know how to make a Tachometer(RPM Meter)
Working principle:-
IR Sensor get penetrate by motion of motor shaft, signal are transfer from IR Senor module to Arduino.
This signal are processed in Arduino according to code loaded on it.Then Arduino transfer signals to LCD Screen to display RPM

Awesome project…brother
Compilation error
Hi, What is value=0 written for ?? it has no use in code ahead ? can it be skipped ??
müzik bok gibi
Bro send me contact no Fast

Excellent!!! Fantastic and thanks for sharing!!!
Can you make it for bike
Will it works for 8×2 character LCD ?
Can someone explain this : rpm=(rev/time)*60.000 ? Why 60.000 . On other sites/videos I;ve seen 30.000 or even 20.000 . Does it have to do with how many white bars are on the circle ( how many times the interrupt functions does ++ in 360 degree turn ) ? Because im using a low voltage to power my motor and it shows +5000 rpm, which is weird cuz its not spinnning that fast and im only using one white line .
Bloody idiotic music. Couldn't watch this vid
I can't upload program to arduino
Please help me
Is there an ardino board that can transfer the RPM info (and plus other data from possibly other sensors) to a smart phone..? For example via bluetooth
इसमे टाइम नहि दिखा रहा है
When building boards , what are the acceptable power /voltage requirements for capacitors, resisters etc as far as wattage and tolerance
can i get arduino code without lcd, but using serial monitor?
Pointless with out an explanation
Good video but I made this thing and my opinion is that this system is NOT very stable and gives fluctuating results. . The most of the sensors don’t work,so you must use the correct sensor and good refective material!
if I want get out put every 100 milliseconds instead of 1 second?????
Thanks it works great, but I have one problem over 32,000RPM it readings change to negative and counts down.

I haven't connected the sensor yet, but at least I see RPM starting at zero.
Assembled this project. Sketch loaded on Arduino Nano but no entry appears on the display. Why?
I wanted to ask you why the code you provided doesn't work? I use Arduino Nano but with other sketches I had no problems. Is it necessary to add libraries for this project here? If so, how do you proceed? Thank you.
You cant use this outside it ll detect the infrared from the sun unless and until you lower the sensitvity of the ir detector or you cover the the sensor receiver.
Annoying music
Why not count rpm in my sensor
is this as accurate as mz80 ?
code arduino plz ;i can't upload it
in ur code rpm = rev/time*60000, what is 60000? please tell me, thanks
Sir I can't load cords to urduino
WTF is that NOISE!!!
Can you please help me to show results on serial monitor instead of LCD.
CAN YOU EXPLAIN ME THE INTERRUPT FUNCTION AND WHAT IS THE PURPOSE TO ADD MILLIS AND OLD TIME
best idea ever seen
If your gonna do a tutorial, loose the horrible music.
Nice video
But I need same circuit and material but coding for counting
Coding please
Hello
very interested in this account turn, I want to know if there is pcb for the electronic circuit or if there is way to download it.
thank you for your answers cordially
Sir project de sokta key plz number 9348305804
I want the arduino code of these .Could you share it?
What if i need to record these reading for some analysis?
Is the code given in the link is it working .
Is this circuit working
I appreciate the knowledge shared. thanks
How the rpm is getting calculated.. I didnt understand the formula in your code plz explain
I make the whole tachometer and upload the program.But LED not shows the name tachometer and rpm..Please suggest the solution
Please send me code for arduino uno without lcd because i want to use serial monitor
i have done this but it shows incorrect speed values is there any solution in the program
Hi,
I implement a tachometer Arduino (nano) with an Infrared sensor. I want to add a stopwatch program to the tachometer program. I want by pressing the button the time to start and by second pressing the time to stop and by third pressing the time is to reset. But since the tachometer program uses a "millis" function i cannot use the millis for the stopwatch. I need help for finishing the program.
I upload the tachometer and the stopwatch programs.
