Hi,
is it possible to use the Arduino UNO with an ESP8266 as an Wi-Fi adapter with SoftwareSerial (or I2C for saving pins) instead of using hardware serial as mentioned in the tutorial with Arduino MEGA?
I read the topic posted a few days before but I don´t understand it.
Will it work if I just change the speed of the ESP8266 and the UNO and in the scetches to 9600 baud (SoftwareSerial has problems with higher speeds than 9600 baud) ?
I already changed the speed of my ESP8266 to 9600 baud for other projects to use with SoftwareSerial.
Another question: In the tutorial the RX-pin of the ESP8266 is directly connected to th 5V-TX-pin (18) of the MEGA, wouldn´t this destroy the ESP8266 which is an 3,3 V device?
Didn´t I need a level shifter (e.g. voltage divider) ?
Greetings and thanks for your help
Ralf
