 ### Step 5. Compile the sketch

 To compile the sketch we have to run the `compile` command with the proper FQBN we just got in the previous command.
 
     $ arduino-cli compile --fqbn arduino:samd:mkr1000 Arduino/MyFirstSketch
     Sketch uses 9600 bytes (3%) of program storage space. Maximum is 262144 bytes.
 
 ### Step 6. Upload your sketch

 We can finally upload the sketch and see our board blinking, we now have to specify the serial port used by our board other than the FQBN:
