The results are presented in the following table:
|
|
First the sensor is placed at a distance of 30cm from the wall and the measured distance is read from the display on the LEGO car. Next the senor is moved 5cm closer to the wall and the measured distance is again read from the display. This process is repeated until the sensor is 5cm from the wall. The results are presented in the following table:
