a variable " servo " is created to address the motor that we connected the Arduino can support multiple servos as long as it can supply power to them and it has enough of those control pins. the closer the object the lower the red plot falls. the red plot is that of the distance calculated by the sensor. in the plot we find a blue triangular wave which is the plot of the angle of the servo. the latest Arduino IDE has the serial plotter so update the IDE. pins of the trigger and echo are defined accordingly. open the serial plotter by going to tools.
trigger, echo, duration, distance are all integers. It can be used as an aid to check inputs to a sketch using LDR’s as input sensors for a project.
This example of the Arduino IDE Serial Plotter is using it as a virtual six channel analog osciloscope, to show the voltage input change at the analog inputs of the Arduino. Servo.h: it is the library required to effectively run the servo motor which requires a pwm signal. Arduino Serial Plotter look at analog inputs.
