Introduction
This motor shield allows Arduino to drive two channel DC motors. It uses a L298N chip which deliveries output current up to 2A each channel.
Specifications
- Motor Driven Voltage: 4.8V to 35V
- Output Current: up to 2A/channel
- Total Power Dissipation: 25W（T=75℃）
- Driven Structure: Dual full-bridge driver
- Driven Power Port: External power terminal, or VIN from Arduino
- Driven Output Port: 2 channel screw terminals, or male PIN headers
- Control Port: 4 TTL Compatible digital signals (Digital 10-13)
- Operation Temperature: -25℃ to 130℃
- Shield Size: 56x57mm
Application
PinOut
-
Power Selection Jumper: The motors can be powered by external power supply(PWMIN) or VIN from Arduino control board(e.g., UNO). Default is VIN showed by the diagram. Note: There are two jumpers in parallel that can afford heavy current.
-
PWMIN Terminal: Used to connect to external power.
-
Motor Terminal: Used to connect motors by screw terminals(M1- M1+ M2- M2+) or PIN headers(1 2 3 4).
-
Analog 3Pin Port: Used to connect sensors or actuators. Note: pinout is (+ - S).
-
Motor Indicator: The red LED lights if Mn+ is positive, whereas the green LED lights.
-
Control Port: Used to control speed and direction of motor. You can get port's description in the "Control Table" printed on the shield.
-
Control Function Table:
| Name | Function |
| En | Mn Speed control(PWM) |
| Mn | Mn Direction Control |
- Control Signal Truth Table:
| En | Mn | State |
| L | X | Disable Mn |
| H | L | Mn Foreward(Mn+ is positive) |
| H | H | Mn Backward(Mn+ is negative) |
Note: n of "Mn" or "En" is 1, 2

Step2: Software List
Step3: Wiring
Step4: Sample Code
- Open Arduino IDE
- Upload the code to UNO
/**set control port**/ const int E1Pin = 10; const int M1Pin = 12; const int E2Pin = 11; const int M2Pin = 13; /**inner definition**/ typedef struct { byte enPin; byte directionPin; } MotorContrl; const int M1 = 0; const int M2 = 1; const int MotorNum = 2; const MotorContrl MotorPin[] = { {E1Pin, M1Pin}, {E2Pin, M2Pin} } ; const int Forward = LOW; const int Backward = HIGH; /**program**/ void setup() { initMotor(); } void loop() { int value; /**test M1 **/ setMotorDirection( M1, Forward ); setMotorSpeed( M1, 100 ); delay(1000); setMotorSpeed( M1, 0 ); delay(100); setMotorDirection( M1, Backward ); setMotorSpeed( M1, 50 ); delay(1000); setMotorSpeed( M1, 0 ); delay(100); /**test M2**/ setMotorDirection( M2, Backward ); for (value = 0 ; value <= 100; value += 5) { setMotorSpeed( M2, value ); delay(100); } setMotorSpeed( M2, 0 ); setMotorDirection( M2, Forward ); for (value = 0 ; value <= 100; value += 5) { setMotorSpeed( M2, value ); delay(100); } setMotorSpeed( M2, 0 ); } /**functions**/ void initMotor( ) { int i; for ( i = 0; i < MotorNum; i++ ) { digitalWrite(MotorPin[i].enPin, LOW); pinMode(MotorPin[i].enPin, OUTPUT); pinMode(MotorPin[i].directionPin, OUTPUT); } } /** motorNumber: M1, M2 direction: Forward, Backward **/ void setMotorDirection( int motorNumber, int direction ) { digitalWrite( MotorPin[motorNumber].directionPin, direction); } /** speed: 0-100 * */ inline void setMotorSpeed( int motorNumber, int speed ) { analogWrite(MotorPin[motorNumber].enPin, 255.0 * (speed / 100.0) ); //PWM }
Step5: Result
M1 will forward at full speed, and then half speed inversion; M2 velocity from fast to slow, reverse first, and then forward.
