This project is REALLY great. Super detailed. But I have a question regarding the LCD1602 Module. How do you get it to stop flashing? I used the code and everything. Thank you! You are AWESOME! BTW- You are very smart.

This is great. I do have a question. I started this on an Uno and had no issues. I moved to a Nano ESP32 and my readings are constantly "LPG:2147483647ppm CO:2147483647ppm SMOKE:2147483647ppm" now. I played with the load resistance variable but it didn't seem to have any effect. Any ideas?
