 ## Execution
 
-To execute the code just open the `todoFindCoolNameForProject\todoFindCoolNameForProject.ino` file using the Arduino IDE and click the Verify and Upload buttons. All necessery peripherials need to be correctly connected to the Arduino board used, more information about the connections can be found inside the `todoFindCoolNameForProject.ino` file and the report.
