What is Arduino?
Arduino is an easy to underst and, easily programmable open source development platform. Over the years Arduino has been the brain of thousands of projects, from everyday objects to complex scientific instruments. A worldwide community of makers – Teachers, students, programmers, hobbyists, artists and professionals. The Arduino software is easy-to-use for beginners, yet flexible enough for advanced users.
Arduino Uno is the most widely used Arduino board. It has 14 digital inputs / outputs (6 PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power input, an ICSP header and a reset button.
There are leds on Arduino. One of them is “ten” led which indicates that it is on. The other one is “L” labeled led, which we will determine its function completely. The other two leds are “RX” and “TX” labeled leds. These leds flash rapidly when there is communication between your Arduino and your computer. “RX” means reception. “TX” means sending.
Arduino can easily design systems that can interact with its environment. Electronic circuit can be installed with Arduino. You can do a lot of applications with Arduino, for this you need to have a little electronic base and a little program writing ability.
Arduino has been used in thousands of different projects and applications. You can do many electronic applications with Arduino. For example; Irrigation systems in your garden, measuring the humidity of your flowers, parking sensor in cars, speedless alarm systems. There are many Arduino boards that you will use in your projects. You can choose the card you want according to the projects you will do.
