Single Load: When the first load having a rating of 200 watts is switched on, the Arduino Serial monitor displays the average power consumed as 170 watts in its COM window as shown in
figure 4(b). Graphically it can be obtained using Megunolink software and processing software. The figure 4.1(b)represents a graph between average power in watts and time in seconds using Megunolink software. Figure 4.2(b) representsthe graph which is displayed using Processing software.
