Motor control shield for arduino

connecting arduino and the adafruit motor shield of the pirate 4wd

The Motor Shield V1 is an expansion board for Arduino UNO and Mega microcontrollers for motor and DC stepper motor control. We have seen how to control a DC motor using the H-bridge which can require a lot of connections when using the simple integrated circuit. In an embedded application, such as a Rovy robot, you will need to control several motors in parallel. There are shields for the shields that simplify installation.
Compatible with the UNO and the Mega, the shield is placed directly on the Arduino board. The power supply is connected to the power terminal block. The motors are connected to terminals M1 to M4. Three types of motor can be connected to it (excluding servo motors):

Shield for Arduino based on the L298P full dual bridge controller, capable of driving DC and Stepper motors. The board, compatible with Arduino Duemilanove, Arduinouno, Arduinomega, etc. … has a terminal board to connect two motors and male / female pins that allow the insertion of other boards in cascade.
The power supply for the motors can be supplied from the outside (7 ÷ 46 Vdc) or directly from the Arduino board. Each of the shield’s two output channels is capable of supplying a maximum current of 2 A, which allows driving two 2 A DC motors or a bipolar stepper motor with an absorption of 2 A per phase. Dimensions: 69.85 mm x 54.60 mm.
The first thing to do before using the shield is to define through the jumper DIRB, PWMB, DIRA, PWMA which Arduino pins are respectively dedicated to the direction (DIR) and speed (PWM) control of the two channels B and A. Figure 1, for example, shows the choice of pins 13 for DIRB, pin 11 for PWMB, pin 7 for DIRA and pin 6 for PWMA. In addition to this, it is necessary to select the power supply for the motors (external = EXT or internal = INT) via jumper JP1. In our case, the EXT source is the one connected to the PWR terminals, while the internal one is represented by the Arduino board. Figure 2 shows, for example, the choice of the EXT source as the power supply for the motors. The two-color LEDs (green / red) LD1 and LD2, mounted on the board, indicate with their lighting the direction of rotation of the motors connected to the board.

The Arduino is a board based on an ATMEL microcontroller. Microcontrollers are integrated circuits in which you can record instructions, which you write them with the programming language that you can use in the Arduino IDE environment.
The Bluetooth module HC-06 allows us to connect our projects with Arduino to a smartphone, cell phone or PC wirelessly (Bluetooth), with the ease of operation of a serial port. … Bluetooth communication is between two types of devices: a master and a slave.
