The All About Circuit’s Understanding Schematics, SparkFun’s How to Read a Schematic, Core Electronics’ How to Use Breadboards, and Science Buddies’ How to Use a Breadboard guides are good resources for learning how to translate a schematic to a breadboard. This tutorial uses a solderless breadboard to build a circuit from a schematic diagram. If you are new to Arduino, or would just like to refresh your knowledge, please see our Blink: Making An LED Blink On An Arduino Uno tutorial before proceeding with this one.

Demonstrating how to provide variable speed control using a potentiometer.Ī basic understanding of electronics and programming is expected along with some familiarity with the Arduino platform.Showing how to ramp up and down a motor’s speed over a specific time frame, and.Enhancing the sketch by checking for any faults that may be occurring on the motor driver,.Using the Motor class in a sketch to perform basic operations,.Constructing a distinct Motor class that interfaces with the motor driver board to provide various methods for controlling a motor,.Connecting a motor driver board and two motors to an Arduino Uno,.This tutorial will teach you how to drive small DC motors with your Arduino Uno. motor.Skill Level: Intermediate Table Of Contents.n() to activate the motor in one direction or the other (RELEASE, BACKWARD, FORWARD).To drive a DC motor, we will use the AF_DCMotor class whose functions are to know: In order to interact with the Motor Shield V1, we use AFMotor.h library. Make sure to check in the component’s technical documentation how to use it (Motor Shield V1 datasheet). In the case of a shield, the connections are predefined. Digital pin 9 and 10 for the actuators 1 and 2.

Digital pin 4, 7, 8 and 12 for communication with the 74HC595.

Digital pin 6: # 4 DC Motor/Stepper # 2 (activation/speed).

Digital pin 5: DC Motor # 3/# 2 Stepper (activation/speed).

Digital pin 3: # 2 DC Motor/Stepper # 1 (on/speed).

Digital Pin 11: Motor # 1 DC/Stepper # 1 (on/speed).

The Motor Shield uses the H-bridge L293D and 74HC595N integrated circuit. Prerequisite : Programming with Arduino, Control a DC Motor with Arduino, Control a stepper with Arduino

A new version of this shield exists, the Motor Shield V2. The Shield used in this tutorial is the Motor Shield V1 from Adafruit. Shields exist for this purpose, to simplify programming and installation. In an embedded application, such as a Rovy robot, you will have to control several motors in parallel. We have seen how to control a DC motor using H bridge which may require a lot of connections when using the simple integrated circuit. The Motor Shield V1 is an expansion board for Arduino UNO and Mega microcontrollers for DC and stepper motor control.
