Infrared Tracking Mode
①Adjust potentiom
【SW3】to make photoelectric sensor【P3】 against white undersurface, then
LED light【L3】illumiinates while against black surface, LED light【L3】goes off.
②Adjust potentiom
【SW4】to make photoelectric sensor【P2】 against white undersurface, then
LED light【L2】illumiinates while against black surface, LED light【L2】goes off.
Caution:Don't excessively rotate potentiometer while adjusting. It should be within 30°.
Obstacle Avoidance Mode
①Adjust
potentiometer【SW1】to make the infrared light-emitting diode【LEAS1】and infrared
light-receiving diode【RC1】away from obstacle less than 10cm, then LED light 【L4】illuminates,
otherwise, it goes off.
②Adjust
potentiometer【SW2】to make the infrared light-emitting diode【LEAS2】and infrared
light-receiving diode【RC2】away from obstacle less than 10cm, then LED light 【L5】illuminates,
otherwise, it goes off.
Caution:Don't excessively rotate potentiometer while adjusting. It should be within 30°.
