In this tutorial you will learn how to use one water flow sensor with an Arduino board.

The water flow sensor consists of a plastic valve body, a water rotor and a hall-effect sensor. When the water flows through the rotor, rotor rolls and the speed of it changes with a different rate of flow. The hall-effect sensor outputs the corresponding pulse signal.

In this tutorial you will learn how to use the WizFi210 – serial WiFi Shield with Arduino uno board. This low-cost wifi shield can be easily connected to your WiFi network and communicate with the Arduino uno board through the serial communication protocol. In this tutorial we will control an LED wirelessly from an Android phone/tablet app or from a computer tcp/ip terminal.

What is the Description Text Editor?
