Hi I hope someone may be able to help me . I have a small line following robot kit ,that uses 3 IR sensors to detech the black tape , it works great ,but for what I need the tape is to wide . The tape is about 3/4 inch or 20mm wide & I need to go down to about 1/16 inch or
1.5 mm . The three sensors are about 1/2 inch or 12mm apart , if i move the sensors closer together will it change the line width. I hope to use it for a profile cutter for my plasma cutter. thank you Allan- posted
