After getting introduced to some of the basic structures of coding, its important to get to know the integrated development environment, or IDE that the coder will use to edit and compile the written programs. For all Arduino boards, the IDE used is the Arduino IDE, available online at: https://www.arduino.cc/en/software. The following figure guides the users to the basic on the basic options available on the IDE:

|-
|Setup()
|Performs any actions that are initially required to run the rest of the program, such as initializing any peripheral components and setting the communication frequency between the Arduino and the PC.
|-
|Loop()
|The loop function acts as the program's driver, it runs on a continuous loop and specifies the order of operation the microcontroller will perform. Execution starts at the top, goes through the contents of the loop and then starts executing from the top again. This procedure is repeated forever.
|-
|pinMode (pin number, INPUT or Output)
|Configures the pin to behave as either an INPUT or an OUTPUT.
|-
|digitalWrite (pin number, HIGH or LOW)
|Writes a HIGH or LOW value to a digital pin. If the pin has been configured as an OUTPUT, then the signal sent over (ie the voltage) will be set as 5 V (HIGH), or 0 V (LOW). For 3.3 V output boards, the high value will be set to 3.3 V, whereas the low is the same as the 5V board, which is 0V.
|-
|Delay (time in milliseconds)
|Pauses the program for the amount of time specified in the parameter.

Variables allow information in programmers to be stored or changed within the code. In order to create a variable within your program, it must be declared. To declare a variable, the coder has to write the type of variable to be declared first. Different types exist, most commonly used are:

===Conditionals===
Conditional statements are programming operations that tells the computer to perform an action for a certain set of conditions. An "if" statement is the most common, and tells the computer to perform a set of actions only if the condition is fullfilled. The syntax is the followoing:
