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 we will use the Adafruit BMP280 sensor. This sensor can measure barometric pressure and temperature with very good accuracy. Because pressure changes with altitude we can also use it as an altimeter with ±1 meter accuracy! Accuracy for barometric pressure is ±1 hPa and ±1.0°C for temperature.
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.
In this tutorial you will learn how to use a voice recognition – serial – module with the Arduino uno board. This module can store up to 15 voice commands. Those are divided into 3 groups, with 5 commands in each group.
This is an evaluation board for the Silicon Laboratories Si4703 FM tuner chip. Beyond being a simple FM radio, the Si4703 is also capable of detecting and processing both Radio Data Service (RDS) and Radio Broadcast Data Service (RBDS) information.
