In this project, we are going to use NodeMCU, and program it to operate in two different modes, namely Access point (AP) mode, and Station (STA) mode. In AP mode, NodeMCU will work like a Wi-Fi router emitting its own Wi-Fi signal, you can use any smartphone to connect to this Wi-Fi network and open a web-page in which we can configure the new Wi-Fi SSID and Password, once the new credentials are set the NodeMCU will automatically get into Station mode and connect to this new Wi-Fi. The new Wi-Fi SSID and Password will be remembered so that the device get connected to this network every time its normally powered on again.
