Serial Conection between 2 NodeMCUs
Simple test of serial conection between 2 NodeMCUs, using SoftwareSerial and Arduino IDE.
This is a test of how two NodeMCUs can comunicate trough SerialSoftware, using Arduino IDE.
1) Get two NodeMCUs
2) Conect pin D7 (RX) of NodeMCU A with pin D8 (TX) of NodeMCU B.
3) Conect pin D8 (TX) of NodeMCU A with pin D7 (RX) of NodeMCU B.
4) Conect GND pin of NodeMCU A with GND pin of NodeMCU B.
