I am new to this field and knowledge , I decided to mke this project for my academics but I am unable to make a ESP32 code in order to take two inputs from ACS712 sensor and subtract them so that the result is displayed.
If you share what you’ve done so far, along with details about how these two sensors will be connected to your mains supply and to your ESP32, and what role Blynk will play in this process, then you might get some assistance from forum members.
