Adafruit motor shield code#

To convert your code from Motor Shield V1 to V2, the following modification should be made: getMotor (1) // You can also make another motor on port M2 //Adafruit_DCMotor *myOtherMotor = AFMS.getMotor(2) void setup () Convert Code from V1 to V2 In this case, M1 Adafruit_DCMotor * myMotor = AFMS. #include #include // Create the motor shield object with the default I2C address Adafruit_MotorShield AFMS = Adafruit_MotorShield () // Or, create it with a different I2C address (say for stacking) // Adafruit_MotorShield AFMS = Adafruit_MotorShield(0圆1) // Select which 'port' M1, M2, M3 or M4. n () to activate the motor in one direction or the other (RELEASE, BACKWARD, FORWARD).motor.getMotor (whole) to select the motor used.To drive a DC motor, we will use the Adafruit_DCMotor class whose functions are: To interact with the Motor Shield V2, we use the library Adafruit_MotorShield.h.

Make sure the component’s technical documentation to use it. In the case of a shield, the connections are predefined. Which mean, you can operate up to 32 shieds (64 steppers or DC motors 128) with a single Arduino. The Motor Shield V2 has jumper to select the I2C address and is stackable.

Adafruit motor shield serial#

It uses fewer pins than the previous version: The Motor Shield V2 uses the MOSFET TB6612 with 1.2A capacity per channel and I2C communication. We will use the Motor Shield V2 and see the improvements over the previous version. To make clean prohect, you can either create your own PCB or use Shields. For motor control, it is possible to use integrated circuits directly but their use requires significant wiring can quickly become unmanageable. Dimensions: 70mm x 55mm x 10mm 2.7"x2.1"x0.The Motor Shield V2 is an expansion board for microcontrollers Arduino UNO and Mega to control DC and stepper motors.Works with Mega/ADK R2 and earlier with 2 wire jumpers Tested compatible with Arduino UNO, Leonardo, ADK/Mega R3, Due, Diecimila & Duemilanove.Polarity protected 2-pin terminal block and jumper to connect external power, for separate logic/motor supplies.Big terminal block connectors to easily hook up wires (18-26AWG) and power.Motors automatically disabled on power-up.Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping.Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution).4 H-Bridges: TB6612 chipset provides 1.2A per bridge (3A for brief 20ms peaks) with thermal shutdown protection and internal kickback protection diodes.2 connections for 5V 'hobby' servos connected to the Arduino's high-resolution dedicated timer - no jitter.Stacking headers, Arduino and motors are not included. Totalling 64 steppers or 128 DC motors!Ĭomes with an assembled & tested shield, terminal block, plain header and jumper. This also makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3.Ĭompletely stackable design: 5 address-select pins means up to 32 stackable shields. Only two pins (SDA & SCL) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or shields to the same pins. This chip handles all the motor and speed controls over I2C.

Adafruit motor shield driver#

There is a fully-dedicated PWM driver chip onboard. It also has much lower voltage drops across the motor so you get more torque out of your batteries, and there are built-in flyback diodes as well.

Adafruit motor shield drivers#

The TB6612 MOSFET drivers have been used in place of the previously used L293D Darlington driver, with 1.2A per channel current capability (you can draw up to 3A peak for approx 20ms at a time). The Adafruit motor shield kit for Arduino gives you the ability to drive up to 4 DC motors or 2 stepper motors and can be stacked to add more motors, leaving the pins on the Arduino free for more inputs and outputs for sensors.
