It's almost considered as a clone. You can also measure the motor current absorption of each motor, among other features. This motor driver shield with PWM speed control mode and the PLL mode, using jumper to switch.It has six digital interface that are not occupied(including D2 , D3 , D5 , D6 , D7 , D9)It has six analog interfaces(A0, A1, A2, A3, A4, A5)It has indicator for forward and backward changing direction .In this tutorial, you need to use this motor driver shield pins stacked on the Arduino Uno. Note that the distance between digital pins 7 and 8 is 160 mil (0.16"), not an even multiple of the 100 mil spacing of the other pins. The Arduino Motor Shield is based on the L298 (), which is a dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors.It lets you drive two DC motors with your Arduino board, controlling the speed and direction of each one independently. This 2x2A DC Motor Shield for Arduino allows Arduino to drive two channel DC motors.It uses a L298N chip which deliveries output current up to 2A each channel. Because the L298 IC mounted on the shield has two separate power connections, one for the logic and one for the motor supply driver. Then, connect the two gear motor to the terminal block of MOTOR A and MOTOR B.Based on the result, the Motor 1 moves in reverse direction while Motor 2 moves in forward direction. The speed control is achieved through conventional PWM which can be obtained from Arduino’s PWM output Pin 5 and 6.

Motor's velocity and directions can be controlled separately and also there are 6 connectors connected to Arduino analog pins.

L298 2Amp Motor Driver Shield for Arduino is based on L298 motor driver integrated circuit, a full- bridge motor driver. It works splendidly, its posses almost all the characteristics of the original Arduino motor shield. It can drive two seperate 2A DC motors or 1 2A step motor. It can drive two seperate 2A DC motors or 1 2A step motor. For your convenience it is calibrated to be 3.3V when the channel is delivering its maximum possible current, that is 2A. The shield's pins, divided by channel are shown in the table below: The Arduino Motor Shield allows your arduino to drive DC and stepper motors, relays and solenoids.If you don't need the Brake and the Current Sensing and you also need more pins for your application you can disable this features by cutting the respective jumpers on the back side of the shield. Four screw holes allow the board to be attached to a surface or case.

You can drive two Brushed DC motors by connecting the two wires of each one in the (+) and (-) screw terminals for each channel A and B.

You can build your own board using the following files:The Arduino Motor Shield must be powered only by an external power supply. DIY Arduino Motor Shield (L298N 2x4A): Today, I'm going to show you how to make an Arduino motor shield (driver) at a low cost.

After 3 seconds, the Motor 1 will forward direction and Motor 2 moves in reverse direction and this cycle is repeating continuously.This video shows the demonstration of the tutorial for L298D 2Amp Motor Driver Shield for Arduino. L298 2Amp Motor Driver Shield for Arduino is based on L298 motor driver integrated circuit, a full- bridge motor driver. You can measure the current going through the DC motor by reading the  pins. Motor's velocity and directions can be controlled separately and also there are 6 connectors connected to Arduino analog pins.

Introduction.

In total there are 8 pins in use on this shield.

Topic: Low voltage output from Arduino Motor Shield L298 (Read 4410 times) previous topic - next topic. On each channel will be a voltage proportional to the measured current, which can be read as a normal analog input, through the function analogRead() on the analog input A0 and A1.

This is possible by cutting the The shield can supply 2 amperes per channel, for a total of 4 amperes maximum. The additional sockets on the shield are described as follow: . The adapter can be connected by plugging a 2.1mm center-positive plug into the Arduino's board power jack on which the motor shield is mounted or by connecting the wires that lead the power supply to the Vin and GND screw terminals, taking care to respect the polarities.To avoid possible damage to the Arduino board on which the shield is mounted, we reccomend using an external power supply that provides a voltage between 7 and 12V. Traveller30 Guest; Low voltage output from Arduino Motor Shield L298…

If your motor require more than 9V we recommend that you separate the power lines of the shield and the Arduino board on which the shield is mounted. In this way you can control its direction by setting HIGH or LOW the  pins, if set HIGH, will effectively brake the DC motors rather than let them slow down by cutting the power. This shield has two separate channels, called A and B, that each use 4 of the Arduino pins to drive or sense the motor. You can use each channel separately to drive two DC motors or combine them to drive one bipolar stepper motor. The Arduino Motor Shield is open-source hardware! The maximum length and width of the Motor Shield PCB are 2.7 and 2.1 inches respectively.

The required motor current often exceeds the maximum USB current rating.External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery.
