Controlling the servo motor via the Serial Monitor

In the previous section, we verified the following:

Whether the Arduino can connect to the internet

Whether the Arduino can send and receive MQTT messages via shiftr.io

Whether the motor is working

Now, let's create an interface to control the servo from the Serial Monitor. Create a new sketch and save it as ch5_01_servo_serial.

Delete the boilerplate code that is automatically added to new sketches (the empty setup and loop functions) and replace the contents of your editor with the following code:

#include <Servo.h>
