Hi all,
I am struggling where I have to start with my Arduino project. Altough it is my first Arduino project, I think it is a really simple one which I could realize within a day.. This is what I would like to do: read the signal from a rpm sensor and switch a output pin to a certain voltage when 6000 rpm is reached (for an engine cut-off).
The following rpm sensor (hall effect) is located on my engine dyno I think: http://www.magsensors.com/pdf/427007-10.pdf .
It also have three connection pins, but in the engine dyno manual they also speak about magnectic pick up tachometer (that's of the inductive type, am I right? not hall effect). So I am not 100% sure. However, let's assume it is the Hall effect one.
The output of this sensor is a block pattern Vcc it shows in the datasheet. How do I know the Vcc voltage? Normally 5 Volt or am I wrong?
When I know this, I could start with the code I think. Or is it not possible to connect the sensor wiring directly to my Arduino. After assigning the board pins I think I have to translate theoutput signal to engine rpm. I think it has to do with the amount of tooth on the trigger wheel, am I right?
When the Arduino could measure the engine speed, it has to output a pin to a certain voltage when 6000 rpm is reached (so else - if statement I think). At the moment I don't know what the output voltage has to be. Therefore I have to do some measurements first.
I hope someone could help me with a start code for this project which I could expand. I am not very experienced with programming language, so that would help me a lot.
Thanks in advance guys!
