sweep servo not working ???

Hi all
sweep servo not working ???

I have my sweep servo pluged in but it doesnt work it is pluged into termanal 6 and has seperate power supply the others work fine but not the sweep servo iam not using the srfo5 sensor

can any one explain why??

here is the code i stole):

int sensorIR = 0;
int sensorUS = 7;

int valIR;
int valUS;

If you go back to your post, click on "modify", then highlight all the code, then click on the # icon in the editor toolbar, your code will be neatly presented and legible in a proper code box, without italics.

Why in heavens name are you re-implementing the Servo library?
