Converting your water meter to a web server

In the previous steps, you learned how to display your water flow sensor's readings and calculate water flow rate and total volume on the Arduino serial monitor. In this step, you will learn how to integrate a simple web server to your water flow sensor and remotely read your water flow sensor's readings.

You can make an Arduino web server with Arduino WiFi Shield or Arduino Ethernet shield. The following steps will explain how to convert the Arduino water flow meter to a web server with Arduino Wi-Fi shield:

1. Remove all the wires you have connected to your Arduino in the previous sections in this chapter.
2. Stack the Arduino WiFi shield on the Arduino board using wire wrap headers. Make sure the Arduino WiFi shield is properly seated on the Arduino board.
3. Now, reconnect the wires from water flow sensor to the Wi-Fi shield. Use the same pin numbers as used in the previous steps.
4. Connect the 9VDC power supply to the Arduino board.
5. Connect your...
