if x>=3.3
    disp('signal recevied soil is dry time to water')
writeDigitalPin(a,'D2',1);pause(0.2);writeDigitalPin(a,'D2',0); 
elseif x>=2.9
    disp('signal received soil is wet but not wet enough time to water')
writeDigitalPin(a,'D2',1);pause(0.2);writeDigitalPin(a,'D2',0); 
else 
    disp('signal received soil is wet')
end

how do i make a loop that keeps running through this if statement until the value of x is <2.9

for x = 0:0.1:5
if x>=3.3
    disp('signal recevied soil is dry time to water')
writeDigitalPin(a,'D2',1);pause(0.2);writeDigitalPin(a,'D2',0); 
elseif x>=2.9
    disp('signal received soil is wet but not wet enough time to water')
writeDigitalPin(a,'D2',1);pause(0.2);writeDigitalPin(a,'D2',0); 
else 
    disp('signal received soil is wet')
