If you are interested, you can learn the working principle of L298N driver module, ultrasonic
module and tracking module by yourself, give full play to your creativity, modify the connection
method and code, and let the car run according to your own ideas.
3. Working principle of L298N drive module
L298N can accept standard TTL logic level signal VSS, and VSS can be connected to 4.5-7V
voltage. 4 pin VS is connected to the power supply voltage, and the VS voltage range VIH is
+2.5
～
46V. The output current can reach 2A, which can drive e-inductive loads. The emitters of
pin 1 and pin 15 are separately led out to connect the current sampling resistor to form a current
sensing signal. L298 can drive 2 motors, and motors can be connected between OUT1, OUT2 and
OUT3, OUT4 respectively. Pins 5, 7, 10, and 12 are connected to the input control level to control
the forward and reverse rotation of the motor. ENA and ENB are connected to the control enable
terminal to control the stalling of the motor.
