Advantages of Arduino Arduino is a microcontroller on a circuit board which makes it easy to receive inputs and drive outputs. A microcontroller is a integrated computer on a chip.Some examples of inputs would be a temperature sensor, a motion sensor, a distance sensor, a switch and so forth. Some examples of outputs would be a light, a screen, a motor and so forth.
Programming Arduino You’ll need to download the Arduino Software package for your operating system from the Arduino download page (http://arduino.cc/en/Main/Software). You also need USB cable to transfer the program from your computer to the board. After opening the downloaded program select board type (Tools > Board). The code you write for your Arduino are known as sketches. They are written in C++. Every sketch needs two void type functions, setup() and loop(). A void type function doesn’t return any value. The setup() method is ran once at the just after the Arduino is powered up and the loop()method is ran continuously afterwards. The setup() is where you want to do any initialisation steps, and in loop() you want to run the code you want to run over and over again. For further details GOOGLE it... All the best !!!
Temperature & Humidity Sensor
