Advise need on what hardware to choose for wheel loader project

Hi,

I repaired an old but big wheel loader (23.000 pounds). Its finally basically running, but lots of small things missing and some issues which I would like to solve using electronics. I want to maybe do also some fun stuff to wireless control some of the features (start/stop the engine, shifting and accelerator).

I am confused at what arduino to use, there so many options ! Below is what I will have as input/output. The Actuators could be a simple on/off relay, but manufacturer says for heavy use it is better to use a motor driver . Simple on/off switch I assume are always analog ?

Thanks for any advise.

Hi , This is one case where a Arduino Mega is right. You have a lot of analog stuff..

See info page HERE

So many wires... See THIS about cables etc.

And a Sensor Shield makes connections a lot easier. See THIS

Let us know how it all goes!

Not every voltage carries an analog signal. Switches signaling only on/off state effectively are digital inputs. Be careful with voltages from the outer world, the Arduino pins will be damaged from voltages outside its 5V operating voltage, i.e. you may need voltage dividers to reduce typical 12V or 24V signals, and most possibly capacitors to filter out spikes on the signal lines. Some electronic skills are required if you want to make a microcontroller work in such a rough environment, and driving high power solenoids or motors.
