Before i go down the rabbit hole any further. Is it possible to create a wireless controller with Arduino via Bluetooth or wifi? My idea is the Arduino would plug into a 9 pin d plug (where the current wired controller goes into a control box) and i would be able to control 3 main functions via an app either tablet or mobile device.
The current wired controller has 3 toggle switches
At the bottom of your rabbit hole is the fact there is NO feedback to your remote that gives the current status of the device you are controlling.
Use an esp32 and follow this tutorial for a single button ( adding 2 more buttons is not difficult ) it uses websocket so you can control it from multiple devices and all will be updated at the same time ( cool )
You also have to add 3 relays ( 2 of which dpst or dpdt )
Could be. Just remember, you are designing something that could be used anywhere in the world and you would not know such minor things as if there has been a power failure at your machine, let alone is some command you gave remotely actually did what was expected.
Yes appreciate that thought. this wireless controller would only be used for testing purposes when the tank its attached to is on a stand once the tank is back on the machine it belongs too its all wired back into a harness.
Also power is on for a maximum of 30 minutes per test cycle. Would that be an issue with Arduino?
Then your own eyes are the feedback mechanism for the project. Do you have an emergency power off switch?
Yes the emergency switch in the controller cuts power which is part of the test but also have a battery disconnect if things go pear shaped
