First of all, make sure to disconnect the Bluetooth module and connect the ESP-01 WiFi board. Check out instructions and test the connection on our resources webpage. When asked for SSID and network key, you need to type in your home WiFi SSID. (The SSID is case sensitive!)
The next step would be to start programming the various components to make sure they work. Check out our workshops for more information.
