Relays control with arduino and NCalc Formula

Hello,

Did you ever figure this out?

Looking to do something similar...

Hi everyone, from the title i want to command one or more relays using arduino by specific NCalc Formula value.

I'm making my own 3D Printed dashboard for ETS 2 with some WS2812B leds, buttons, segments display and some 3,5 - 7 inchs screen

I want to turn on a Relay if the value [GameRawData.TruckValues.CurrentValues.DashboardValues.WarningValues.AirPressureEmergency] is true

Hello. I'm not fully understand your requirements, but in order to make some if statement and return the value 1 if true, and 0 if false, it should be something like this. 

Set in simhub ncalc binding

if([GameRawData.TruckValues.CurrentValues.DashboardValues.WarningValues.AirPressureEmergency], 1,0)

Then to control your hardware device(i.e arduino), set in your ShcustomProtocol.h file something like this

int myLed =FlowSerialReadStringUntil('\n').toINT()

This is as far as I remembered. Sorry, this code were not tested, as I'm not in front of my pc. You can try to see example 2 in the ShcustomProtocol.h script as your reference. 

For the beeper, I've only use it in the dash. I am mapping a trigger event that will make a beep sounds on my pc whenever some requirements are met. I need to set the requirements in the sample.ini script as an "ExportEvent". 

It will look something like this. 

[ExportEvent]
value = myBeep
trigger =[GameRawData.TruckValues.CurrentValues.DashboardValues.WarningValues.AirPressureEmergency]

Try to adjust trigger code as needed.

Next, in the "control and events" tab on left side of simhub, your new event will be recognised as ExternalScript.myBeep. 

Ensure that you restart simhub after saving your sample.ini files. 

Good luck, have fun
