 +===== What to expect ===== 
 + 
 +Introduction to microcontroller programming, focused mainly on Arduino platform. We will start with basics, what to expect from Arduino and what is Arduino capable of with some examples. Then theoretic part, how to connect everything together and mainly how to write programs. Thus everything from using basic C skills to Arduino specific functions.  
 + 
 +As we learn enough of theoretic background, you will get your hands on Arduino boards and you will have chance to program your own blinking LED or something similar, depending on your time, skill and enthusiasm.

-Analog pins are used for analog read, when we need more precise value than just binary 0 or 1. Output from these pins can be anything between 0 to 1023 and we use these pins for reading values from sensors, i.e. humidity, ligth, distance etc.+Analog pins are used for analog read, when we need more precise value than just binary 0 or 1.

 Last category of pins are power pins, these are ground pins, 5V and 3.5V pins. Connect these to power breadboard power lines or components directly, as needed. Last category of pins are power pins, these are ground pins, 5V and 3.5V pins.

 +=== Sensors, Analog input and Serial monitor ===
 +
 +Next example will show, how to read values from sensors and how to obtain debugging information from Arduino board.
 +
 +In order to receive value from sensor, we have to use analog input pins (Arduino UNO has range from A0 to A5) and read values with analogRead function. There are many posibilities what to use as a source of input, you can choose from whatever is avaiable, rotary potentiometer
