Adjust the sensitivity of IR Obstacle Avoidance modules
Turn on the car, put object about 10cm ahead of each IR Obstacle Avoidance
modules and adjust potentiometer on IR Obstacle Avoidance modules to
detect object or your hand.
Note: When these module detect objects, the power indicator and signal
indictor are on. When you move object over detection distance, the power
indicator is on. If the signal indictor is always on even though the object is
over detection distance, you also need to adjust the potentiometer
Final testing
Turn on the car, move object or your hand ahead of car, and then the car will
move accordingly: looks like you pull it. It goes forward when both IR Obstacle
Avoidance modules detect object or your hand; it turns right when the right IR
Obstacle Avoidance modules detect object; it turns left when the left IR
Obstacle Avoidance modules detect object.
When object or your hand is over 10cm ahead, it will stop.
Note:
1) As IR Obstacle Avoidance modules are installed at the back of the
