Please excuse me I didn't know what Arduino was until a few days ago. Since then I've been fascinated.
I would like to make a way of identifying oil and coolant temperatures in my car.
Originally I thaught of blue leds when the engine is cool. Which go off when upto temp. And red leds when an overheat risk occurs.
Now after seeing what's available a 2 line lcd display that simply displays the temperatures would seem a better solution. I dont know where to start designing the circuit.
But I can say that the thermistors I have are two wire. Not 3 like the Arduino temp sensor.
And we know the vehicle operates at 12v DC.
Please can anyone offer some help to get me started or any guides? I have seen many people doing the same project for automotive use on YouTube but most and in another language and showcase the finished article rather than hint at how it was created
I can solder well etc. But I am noob to electronics.
Your approach with LEDs is not unreasonable, would be easier to install in the car than any display, and likely as not use the thermistors you apparently have in your hand. Any accuracy issues with thermistors are not relevant in automotive use.
There is no such thing as an "Arduino temp sensors", pretty well any temp sensor can be used with Arduino. The thing about Arduino is that it is a good vehicle for utilising those sensors, recording, disptaching, and displaying data. A particular case in point is using Arduino with "3-wire" sensors.
I would suggest you get used to using Arduino and your sensors before you go to put them in the car.
Your reply is greatly appreciated.
When saying Arduino temp sensor was generally referring to the guides i have seen which use a ds18b20 which has three legs.
The thermistors I have are designed for automotive use and have only 2 wires.
I suppose I best order some parts and get started playing around with it.
Hoping my brother will help with code as he has a good understanding of c
automotive sensors are typically 3 wire. the chassis is ground and the 3rd wire.
of course, you can use any sensor you like. if you know the voltage or current, let us now and we can help.
lots and lots of options.
blue = cool, green = normal, red = hot.
neopixel will allow you to have one LED that changes,
maybe flash at times.
