摘要：This study implements an Arduino obstacle
avoidance car and provides automatic path map drawing
function. The L298N is used as the driving circuit, the PWM
output from the Arduino is used for speed control, and the
infrared sensor is used to emit infrared rays at a certain
frequency to detect obstacles, and all the detection signals are
sent to the Arduino. The Arduino acts as a control core to
change the speed and steering of the car to achieve automatic
obstacle avoidance. In addition, through the NodeMCU as a
server, the PC is connected to the NodeMCU as a client, and
then the data is transmitted through the socket connection, and
the obtained data is drawn into a path map by Unity, thereby
realizing the real time transmission function of the path map.
