My problem is somewhat minor but with a major root of inexperience . I am working on a project to measure energy and turn off an on power from a relay using the reading . I am using the open energy monitor and i have been seriously trying to make this work with megunolink . My problem comes in 2 parts.
1. I need to set the order in which the relay has to be turned off based on user input. So for this i made a gui with a drop down button . so i need megunolink to read the value and send it to the arduino as an integer . Someone helped me earlier by using case structures but i only got confused since its different from my setup (thank you Paul) .
2. I need to plot the values i am getting onto 5 separate graphs and allow the user to select a graph by choice , i have not gotten to this part yet but from the tutorials i seem to have the hang of it . My major worry is the first problem this not soo much
Below is my code and what i have tried soo far . i dont know to what extant you may help me .. or if it is possible ...
