The purpose of this experiment is to find out the speed and
accuracy for updating data from sensor controller to master
controller (PC). Each sensor controllers have addresses, which
are address A until address Z. Based on the program in master
controller (PC), the time needed for master controller (PC) to
send an address from A to B is 20ms. Therefore, to send
address from A to Z and back to A will need 26 x 20ms, which
is 520ms, but for the master controller to show the updates
from the received data from each sensors from sensor
controllers is 1 second and it is shown in the table below.
