موتور شیلد L298 MOTOR SHIELD R3:

The Arduino Motor Shield is designed to drive miscelleneous inductive loads such as:

Relays
Solenoids
DC and stepping motors
If you are looking to use Arduino Motor Shield for a robotic project such as a mobile robot, you need to know that the Arduino Shield can drive independently the speed of two DC motors. You can also measure the motor current absorption of each motor, among other features.

Motors connections
Brushed DC motor connection is done by connecting the two wires to the + and – screw terminals for each channel A and B. You can control its direction by setting HIGH or LOW the DIR A and DIR B pins and speed by varying the PWM A and PWM B duty cycle values.

If set to HIGH, the A and B Brake pins will effectively brake the DC motors rather than let them slow down by cutting the power. You can measure the current going through the DC motor by reading the SNS0 and SNS1 pins. 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. For your convenience it is calibrated to be 3.3V when the channel is delivering its maximum possible current, that is 2A.

Features
Motor controller: L298P, Drives 2 DC motors or 1 stepper motor
Max current: 2A per channel or 4A max (with external power supply)
Current sensing 1.65V/A
The Arduino Motor Shield must be powered only by an external power supply. External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. To avoid possible damage to the Arduino board on which the shield is mounted, we recommend that you use an external power supply with an output voltage between 7 and 12V. If your motor require more than 9V, it is recommended to cut the “Vin connect” jumper placed on the back side of the shield.

Inputs Outputs
This shield has two separate channels, called A and B, that each use 4 of the Arduino pins to drive or sense the motor. In total there are 8 pins in use on this shield. You can use each channel separately to drive two DC motors or combine them to drive one bipolar stepper motor. The shield’s pins, divided by channel are shown in the table below:

Function Pins per Ch. A Pins per Ch. B
