Hello, thank you. I have modified your code for my application and attempted to simulate it in TinkerCAD using the IR Remote and IR Sensor but I am getting multiple counts when a button is pressed. Maybe a debounce is needed on the sensor or in the code?
Hi there, thanks for your very performative video, Can I ask how to add 2 outputs to control the motor speed base on rpm reading and rpm setting to maintain the desired speed?
I'm going to use this with ESP8266 so I can show RPM value in webpage. Can I use 3.3v to supply power to this module? what output voltage from this module?
Hello friend, my Optocoupler is one of those used in printers, which has 4 wires, two for power and two for signal, so how can I use it in your code, given that yours only has one signal pin... (attachInterrupt(digitalPinToInterrupt(2))? Thanks
Hi there, thanks for your clear explanation about this setup. I got it working because of your video! But what if I want to have a second RPM reading on the 16x2 display with a second Optocoupler sensor? How do I adapt the code for this situation?
you need to make a second counter function with different variables, and don't forget to attach interrupt on digital pin 3 since arduino like UNO or NANO only has interrupt pin on pin 2 and 3. Then print the second value on a different LCD coordinate (assuming use 1 LCD).
Hello. Can you help me how to attach my servo with RPM meter? So when the RPM is below the specified, the servo will automatically rotate and stop when RPM become normali again
Tambahin library servo aja mas, kayak di file example. Abis itu bikin if else sederhana. If (RPM < batas) { servo.write(sudut yang diinginkan) else {servo.write(sudut lain) }
hey bro, my interupt triggers way too much giving too high reading, could it be the wheel is too thin? also the wheel is slightly warped could this affect it?

Very well expleined thank you from Morocco

How much will this be affected by EMI noise?
please sir could you tell me what the knd of motor you have used here ?

Find the digital output, and use that pin.
Interessantes Video, *danke* .

Thank You so much.That was Very Useful!!!
Can one do this with Arduino Nano?
Sure, you can do with any arduino
Hi miliohm, after I verify the code in arduino, a warning appears "count was not declared in this scope". Can you help me how to fix that?
make sure you copy the whole code. Sometimes it caused by lack of curly bracket

To ,my case
km/h = 5.97 * rpm *0.001885;
Glad to hear that. What's the diameter of your encoder?
hey bro, my interupt triggers way too much giving too high reading, could it be the wheel is too thin? also the wheel is slightly warped could this affect it?
Try to turn wheel slowly. Does it only add count every passing hole?
@@miliohm no by the time it passes around 10 holes, it has picked up more than 100 holes
@@koekie7003 try to paint your wheel. If it 3D printed sometimes it still can be penetrated by the infrared.
@@miliohm I will try it thank you
hii bro, how to convert rpm to km/h??
Can u share 3d file disk holes sir ?
Maaf mas lupa udah ga kesimpen

keren
Can I get the circuit

Hallo mr
Hi very good thank you), it possible to write you in privat please?
