Using Arduino and l298n (red Board) to drive DC motors

l298n Introduction

l298n Drive module, can drive 2 DC Motor , can be used to achieve positive turn , reverse function.

Arduino Uno + l298n driver module wiring

Note: If the voltage is not enough , the motor may not turn oh, so to external 7v-12v power.

Program source code to upload the program to the motherboard, connected to the external power supply, the motor will turn up.
Here the IO port is selected as 5,6,9,10, which are all fourSupportPWM, which can be achieved through the duty-free codeControlTurnSpeedThe speed.
