DIY RPM Tachometer with Arduino | RPM Counter |

This video will teach you how to make RPM Tachometer, which helps you to check the speed of any motor.
For making this you required an Arduino, OLED Display, Optical sensor, Breadboard and few jumper wire which are very easily available in the market.
For more information please visit the project page where you can get the circuit diagram and program code for Arduino.

Working great. 1440 or 1600 rpm. Accurate

Great project and video, thanks and /subscribed!

You can find that sensor in an old tape recorder. But wiithout the circuitry. How can I hook it up, it has only 2 wires. the black always goes to neutral.

not a very thorough video.. But gives birth to ideas.. thanks

How do I calculate rpm to km/h and display it on the LCD screen?
need the coding.. please

Hey there, I am running a wind turbine experiment. however, I will have wind turbine that will generate energy it will not have a power source producing energy to the wind turbine. We have a DC motor we are treating as an AC motor and using a counter fan to blow the wind blades. We want to track the RPMs of the motor through LabView, do you think it will be possible to track our motor with your setup?

Great tutorial. What is the voltage and current requirements for this setup? Have any of the components become smaller and easier for plug and play in the last few years?
Cheers

So for the sensor all we need it power and ground, and pin out from sensor to pin 2 on arduino? Can't find a circuit diagram on your website

hey. would you make someday arduino anti lock braking system. here is my idea. the rpm sensor detect the wheel running. the other motor will act as brake. so i want to know if its possible? if you do braking the motor act as brake to wheel with rpm sensor. the motor will move on off on off in a fast second unti the wheel will stop running and then the motor will act as a brake. so the final step of motor brake will lock wheel after the wheel. rpm stop. im sorry for my english. but I'm hoping you will understand what's my idea.

Can u make similar tachometer with stm32?

[АндрейХудобко-ют]

the library does not work, why snimati video

[dallimariam]

hi ? i need help , to do the same things but using an LCD and photoelectrique speed wheel encoder, but i don't know how to create the programme .

[dhanushr]

What is dat sensor u hav used in this..?
Actual name of it...

[soumyamalik]

Can I get the full & proper circuit diagram of this project?

[ahmeds_.x]

why not show accurate value?
This value up down continuously. Why?

[rho]

how would you modify de code for it to count the number of turns or total times it passes through the sensor rather then the speed? I´m stuck any help would be appreciated

[lunaticdevil]

What if we use two sided paper blade, what will be the changes in code

[olddognewtricks]

Hi, whats the maximum rpm this can detect?
I need 10 to 13 x 1000 rpm. Is this possible?
Thanks,

[mars.]

Hello, what is maximum RPMs this optical sensor can handle? 10000? 30000? Thx

[khawajaareeb]

i want to store the rpm value in my computer (may be an excel sheet) so i can make a voltage VS RPM graph. how is that possible? can i get any help on this?
