Alright, so I'm stuck on a detail and don't know where to look for solutions.
Details: I'm using Node-RED on a Raspberry pi to communicate with an Arduino Uno that has the Standard Firmata sketch on it - all it working fine.
However here is my problem, and I'm not sure where to go next:
I want to read sensor data that is connected to the Arduino. Namely a ACS758 current sensor or any Hall effect current sensor, I'll need to connect two of them.
So, I can access the analog pins on the Arduino just fine. But, I need something that will translate the data and I'm not sure how to do that. normally, I would just upload a sensor library onto the the arduino and access it with some kind of code. But, I cant really do that now.
I know this isn't specifically a Arduino question, it's more of a node-RED question... but I thought that maybe there could be some kind of modification to the Firmata code that could be done to communicate that data as well. Unfortunately, I'm kinda new to arduino, so that's why i came here for help.
