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?

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?

Thank you for your help. To ,my case km/h = 5.97 * rpm *0.001885;

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 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

Find the digital output, and use that pin.

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) }

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

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?
