Hello, I have an Esp 01 and Arduino mega.
My project is to install wifimanager on the esp01 with 8266 chip, connect it to the arduino mega through Serial3.
I put the code that I am using without success, I need help my level of programming is very low,
I have Esp 01 programmed with wifi manager and it works ok connects to wifi very well
If someone can help me I appreciate it, thanks

Thank you Pete for your answer I already thought that it would not be possible. But I needed a professional to confirm it for me.
I have a code that works fine for me but I can’t integrate Wifimanager which was my purpose.

You need to use a more modern device, such as NodeMCU or ESP32 if you want to use WiFiManager, but if you do that you’d be better using Blynk Edgent as this does the WiFi provisioning in a much nicer way than WiFiManager.
ok Pete but it is a sensor that works from 0 to 5 V depending on its value the votage could be 2.5 v, 1.5 v etc.
Would you make me a good conversion for your reader of the esp 8266 A0?
