Hello there! your code trurly does wonders! althought I'm facing an issue which is that I'm using a hall effect sensor to measure a wheel's rpm. The wheel is connected to an electric threephase 18kw motor, and when the motor's RPM are > 150 the arduino stops working showing random numbers on the serial screen. I've tried using shielded wire and that does help (connecting the shielded wire to the arduino's and sensor's GND). Now i want to use a pull up resistor, but the issue I'm facing is: When do i use pull up and when do i use pull down? I'm not sure if im gonna be using a NPN or PNP NO or /NC hall sensor. I think if it's a PNP then its a pull down resistor and viceversa? Or which sensor type should I use? many thanks! hope you could provide me with some help!

@interlinkknight 8 күн бұрын

The question about when to use pull-up or pull-down resistors is very simple. If the device (in this case the hall effect) output gives a ground signal, then we should use a pull-up resistor. If the device outputs voltage when it send a signal, then we need to add a pull-down resistor. For this case, the A3144 output signal is ground so I added a pull-up resistor to keep it HIGH when there's no signal.

@francescoranchi7415 8 күн бұрын

@@interlinkknight ok I think I got it! So to give the arduino a steady signal while the sensor if “off” state, we use a resistor which pulls opposite to the sensor’s output signal type? So I guess the sensor’s signal is “stronger” than the voltage given into the arduino by the resistor therefore it is overcome by the sensor output signal?

@francescoranchi7415 8 күн бұрын

Also if I use pull up or pull down , do I need to change in the code the attachToInterrupt to be rising if I’m using pull down, and falling if I’m using pull up?

@interlinkknight 8 күн бұрын

That's correct. The rising or falling is pretty much irrelevant

@francescoranchi7415 8 күн бұрын

@@interlinkknight Ok super! many thanks, one last question, If I use for example NPN with pull-up and "FALLING" it must be a NO, otherwise if it's NC i need to write "RISING", is that correct?

Thanks a lot for this tutorial! I have few questions: I would like to make a "shifter" for my motorcycle. The system would work like this: when I press the speed selector pedal, via a micro-contact I cut the ignition for xx ms depending on the engine speed while I shift into gear. The micro-contact would be connected to an input of the Arduino and an output of the Arduino would control a Mosfet to cut off the ignition. Would these inputs/outputs prevent your program from functioning correctly? Can you help me?

@interlinkknight Ай бұрын

You could run that program without affecting the tachometer code because the tachometer counts the pulses using interrupts that are not affected by the main loop

@ericksonhernandez2070 Ай бұрын

is there any way to potentially do this but instead measure the current through the spark plug to determine rpm? it's just 12v right?

@interlinkknight Ай бұрын

You would have to convert that high voltage of the spark plug to 5V. Also check that the signal is clean (no spikes or multiple HIGH/LOW on a single pulse). Then, it should work

Do you mean the OLED display? You would have to put a few if statements that if RPM is between 0 and 9 the text x position is a value in the center. If RPM is between 10 and 99 the text x position is a value in the center. If RPM is between 100 and 999 the text x position is a value in the center. Etc.

Thank you, this is a great project! The most comprehensive guide. I am running this succesfully with one sensor and 4 magnets, but my readings are only starting at 18-20 rpm. I was wondering if adding more magnets and a second sensor would get me lower readings between 1-18 rpm. Also should I place the second sensor on the opposite side of the 1st sensor?

@interlinkknight 3 ай бұрын

I don't recommend adding another sensor. To read low speed you just need more magnets in the wheel/shaft. The more pulses per revolution, the lower RPM you can measure

@ashkenaze 4 ай бұрын

Hmm.. Disconnected power rail should be an advantage/plus rather than the opposite. You virtually have separate boards for 4 different voltages With your logic ALL breadboards failed this because ALL of them have at least 2 disconnected power rails.

@interlinkknight 4 ай бұрын

In cases where people require 3 or 4 power rails, that would be an advantage, yes. The question would be: how many times do people use 1-2 power rails vs 3-4 power rails? Maybe like 90% vs 10%? Good brands know this so neither of the good brands add this feature of splitting the power rails, at least that I know of. In that case, you would have to buy a bad quality breadboard so it can have the split power rails, but now you would suffer the bad connections, the bad labels, etc.

Would I be able to use Arduino base tachometer on my home made gas turbine as it is going to have an RPM of something in the area of 130,000RPM + - 10000RPM and secondly would I need to colour the compressor white and black for easy counting? Thanks

@interlinkknight 4 ай бұрын

At that speed, it would work but only if you create one pulse per one revolution, and you don't do much else on the code. Above 150,000 Hz it starts having issues to run the main loop. In those cases I would just use a faster microcontroller like the Arduino UNO R4 or ESP32 that can handle a lot faster speeds. About the second question, you only need a white/black color contrast on the shaft if you use a reflective sensor. I show 3 kinds of sensors in the video, and each has their own way to detect the pulses. One is a magnet, the other one is creating an obstruction from the emitter to the receiver of the sensor, and the other one is reflective that requires white/black colors. Depends on which one you use.

There are many ways you can handle that. Usually, the LED would stay ON and the toggle switch on the display would reset to the default value once you go to another page, but you can make it a global variable so it can remember the state, no matter in what page it is.
