Connection Of Arduino And Sensor; Diagram Of Distance Detection Adjustment; Experimental Procedures - Keywish Hummer-Bot Instruction Manual

Note: This module can adjust the detection distance by the potentiometer, the detection distance is 2-
30cm, if it is found that the distance detection is not very sensitive, you can use the potentiometer to achieve
the desired results ( rotating the potentiometer clockwise will increase the detection distance;
counterclockwise will decrease), it is shown in Fig.3.2.10.
Manual adjustment is shown in the following diagram:

3.2.2.4 Experimental Procedures

1, Fixing the two sensors on the car and connecting them to Arduino with wires.(Already done)
2, Testing the sensitivity of module, namely opening the switch on the battery box and the indicator will
light, placing obstacles the 10cm away from the infrared tubes, adjusting the potentiometer until the output
indicator lights up.
