RPM meter with arduino DIY (IR sensor and 3D printed case)

Easy to build, 3D printed and homemade RPM meter/Tachometer with Arduino. The circuit is easy and based on a IR LED and phototransistor. You have all the codes, schematics and STL files below. I hope you enjoy it.

I hope you enjoy it. If you have any question don't doubt to ask it on my Q&A page or here. The project could always be imprroved with better code, better IR sensor and a faster microcontroller. Keep up guys!

I did something similar with a laser & an IR sensor I pulled from a tv RC receiver. Its been years but i remember I was able to get 60k. of course that took some tuning. it was 5k out the gate. Eventually I used atmel studio to reduce the bloatware on arduino. Like I mentioned> its been years, but I remember getting more like 100k or 200k.... I should clarify >> its good and very useful bloatware. Its really good to have quick access 2, caz programming in atmel studio was super bare bones. There is much goodness in the arduino ide already hooked up. Much I didn't know I was taking for granted until it was gone.... so ya its not that big of a deal to use atmel studio, just be prepared to strap yourself in and read that 1000k length datasheet. btw, measurements = signal generator + oscilloscope . and yes it totally works to measure spindle speeds, that why I made it. There is a lotta power in a laser. U could use an old cd player as well, its got a laser&diode right there :)

Nice tutorial and well documented and presented! I will subscribe!

[MuhammadWaqar-nine]

again you are awesome ... great video nicely explained ... loved it ..

[chiparooo]

Very interesting. Thanks for explaining what everything does. Learned a lot.

You could just remove the on off switch and replace it by a button. So if you push it the device starts up and reads the rpm, after you release it again it simply turns off.

Amazing video! Loved it! Liked and subscribed!

great video. I think, you love potentiometer😀

[rengarider]

superb 👏 👏 👏, I have one idea can i use normal infrared obstacles avoiding sensor, it will be more simple in circuit designs, Am I right???

[enriqueslife]

It's awesome. But how to make a laser tachometer instead of IR using laser module like proffesional non contact laser tachometer? What will be the changes?🤔 Please make a video if possible. It will be a good staff. Thank you.🤠

[RGPinger]

Hello there, I found your tutorials today :O And I must say, they are great.. :) I subbed u.
Can I ask you, what methods for measuring is the best? Using infrared like you, or magnet with hall sensor or Optocoupler sensor? :) Thanks

[anmoldubey]

once again ...a great video...grt explanation...i will surely make one....😋
