-  WiFi Web Server LED control via web of things (e.g., WebThings Gateway)
-  based on WiFi101.h example "Provisioning_WiFiWebServer.ino"
-
- A simple web server that lets you control an LED via the web.
- This sketch will print the IP address of your WiFi device (once connected)
- to the Serial monitor. From there, you can open that address in a web browser
- to turn on and off the onboard LED.
-
- You can also connect via the Things Gateway http-on-off-wifi-adapter.
-
- If the IP address of your shield is yourAddress:
- http://yourAddress/H turns the LED on
- http://yourAddress/L turns it off
-
- This example is written for a network using WPA encryption. For
- WEP or WPA, change the Wifi.begin() call accordingly.
-
- Circuit:
- * WiFi using Microchip (Atmel) WINC1500
- * LED attached to pin 1 (onboard LED) for SAMW25
- * LED attached to pin 6 for MKR1000

+## BME 280 WebThings example
+
+In order to be able to use this example, you need to install the WebThings library.
+
+Change the ssid and password to connect to your router
+
+```c++
+const char *ssid = "";
+const char *password = "";
+```
+
+Make sure the BME/BMP 280 has the correct I2C address (0x76)
+If it doesn't work or you know you use the other address, change it in
+
+```c++
+BME280I2C::Settings settings(
+   BME280::OSR_X1,
+   BME280::OSR_X1,
+   BME280::OSR_X1,

+   BME280::StandbyTime_1000ms,

+   BME280::SpiEnable_False,
+   BME280I2C::I2CAddr_0x76 // I2C address. I2C specific.
