Using two or more Winson WCS Hall Effec Current Sensors with Arduino

This tutorial by Robojax explains the WCS1800 Current Sensor, shows how to prepare wiring, explained the Arduino Code and at the end demonstrates measuring DC Current from 0.5A to 35A.
The code is to use two or move WCS Sensors. If you want to use only single sensor, then use the code shown Here.
