% This program is the basis for Week 8, EGR 102 in class assignment to % build a weight sensor. This initial program will read your weight sensor % and tell you what value you are getting. The while loop will allow it to % read over and over again. %a = arduino('com3','uno') %only needed if arduino not connected weight = zeros(1,100); %holds voltage reads AveValue = zeros(1,100); test = 0; %sets initial test number while 1==1 %continually run test =test +1; %defines test number AllValues = 0; % set initial average of this test to 0 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%% %%%% Add your code to enter a for loop here %%%%%%%%% %%%% Create an idex variable to hold %%%%%%%%% %%%% The current sensor value %%%%%%%%% %%%% Sum them up in 'AllValues' %%%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% weight(test) = readVoltage(a,'A0'); %read from arduino pause (.5); %slows down read speed %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%% End the loop here - but you are not yet done %%%%%%%% %%%% To get an average you need to divide by %%%%%%%% %%%% The number of samples - do that too! %%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% plot (weight); %plots values, change the variable to your average title ('Weight sensor readings'); ylabel('Voltage from sensor'); %label Y axis % call your result AveValue and uncomment the line below %fprintf ('test %d = %.4f \n', test, AveValue) %prints values end %end while loop
