Before you can use the Motor shield, you must install the AF_Motor Arduino library - this will instruct the Arduino how to talk to the Adafruit Motor shield, and it isn't optional!

I had an old motor shield kit lying around so I decided to build it and use it. Problem is, when it is on my Leonardo board I get a complying error when compiling the example code from Adafruit motor shield library.

I have checked to make sure there are no additional files with that name and I used the manage libraries option to add the library rather than using .zip file. I only thing I can thick of is that my Leonardo board as an updated chip version and the version 1 motor controller can communicate.

The Leonardo uses the ATmega32U4 microcontroller. This is different from the Uno, which uses the ATmega328P and the Mega, which uses the ATmega2560. It looks like support for the ATmega32U4 was never added to the Adafruit library. Adafruit has retired that library, so they will never add ATmega32U4 support. However, there is a fork of the library where a 3rd party did add support for the ATmega32U4:

Hello friends,I mention robotic applications in motor drive, one of the most widely used card adafruit L293d company that developed the integrated bar from Adafruit motor shield motor driver card. The main reason for the preference because of the connection can be installed on the arduino is provided in a practical way. First, the library board to look at the overall structure of the pin and then use the card and I'll explain the meaning of the function. Using the library card is also a great advantage in terms of software.

Drive over 2 servo input located on.The driver to drive the servo does not have its own library functions. You can control servos using the normal servo library. Servo1 entry by arduino digital pins on the 9th,Servo2 is connected to the input pins by the arduino's 10.dijital. Whether the user's convenience it made 2 servo input.

It's probably because the compiler can't locate the header file. Make sure you either move the library with header file to the default Arduino libraries folder or move the library to the same directory as your Arduino code and then try:



We finished porting the AFmotor library to the Arduino Mega, if you have an Arduino Mega & and an Adafruit motor shield they now play together nicely.What is the Adafruit motorshield for Arduino?

However, when I install the library (regardless of whether I do it using the in-built library manager or by downloading a zip and moving it to the relevant folder), the following errors get thrown on compilation.

I searched on internet if I could get any idea for that, but everywhere people were just using "AFMotor.h" library and it will be very difficult to use that library's given functions in our robot, if we want to control our Robot using RemoteXY's joystick. So, I finally came here for help from you experts.

I'm currently taking it to the next step and add a Labview interface. I managed to set up my Labview software to work with the Arduino and did a simple blinky test and it worked fine. I had to use the Labview for Arduino Interface library to get this working.

I am having trouble with the Radiohead RFM95 encrypted client example, seems Speck.h shows as no such file or directory. I can find code for Speck.h but not as a file I can drop in my library. I imagine there is a way to create the right file type in VS but I am not familiar with how to do that, assuming that would even do the trick. I would appreciate a little help here as I am rather new to Arduino and C++.

5.Place the AFMotor folder into your arduinosketchfolder/libraries folder. For Windows, this will probably be something like MY Documents/Arduino/libraries for Mac it will be something like Documents/arduino/libraries. If this is the first time you are installing a library, you'll need to create the libraries folder. Make sure to call it libraries exactly, no caps, no other name.

Stepper motors are great for (semi-)precise control, perfect for many robot and CNC projects. This motor shield supports up to 2 stepper motors. The library works identically for bi-polar and uni-polar motors

6. The stepping commands are 'blocking' and will return once the steps have finished. If someone wants to be awesome and write a version of the library that does background stepping that would be cool! :)

If you use the AFmotor library (adafruit shield) with IRremote, there is a conflict on TIMER2 (pin 3). If you do not use pin 9 for PWM issues in AFmotor, you can modify IRremoteInt.h in IRremote library by uncommenting the TIMER1 line instead of TIMER2 like below

This is a continuation of the previous post where we have tried to run a servo using an Arduino motor shield. This was a simple task to do with the Arduino Servo library. Today we will push things a bit forward and drive the DC motor using the same motor shield. This motor shield can run small DC motors that require less than 0.6A of current and operating voltage is less than 25V. In my drawer, I found a small 12V motor that will fit this demo. Before we begin programming, we need to connect the motor to the Board. We are going to use the M1 connector.:

We can try running using standard Arduino commands. But why bother if there is already a great library to drive motors using a few commands. First of all, download AFMotor library from GitHub. Unpack it and copy the AFmotor folder to Arduino->libraries folder so that AFmotor.cpp and AFmotor.h files were in the top level of the folder just like this:

Another part of the program is self-explanatory. It simply drives backward and forwards, gradually speeding and slowing. As you can see, driving DC motors is also an easy task. Arduino motor shield allows driving up to four DC motors simultaneously in both directions. By tweaking the AFmotor library a bit, you can practically drive 8 DC motors single direction where one motor pin is connected to the control signal and another to the ground.

The Arduino sketch begins by including the AFMotor.h library. The next line creates an object of the class AF_DCMotor. The instantiation of this object requires mentioning the port, where the motor is connected, and the second parameter, which is the motor speed control frequency.

The Arduino sketch begins by importing the servo library. The next line creates an object of the servo class. The method here assigns the servo control pin. The write method is used rotate the servo to set angles.

The Arduino sketch begins by including the AFMotor.h library. The next line instantiates an object from the class AF_Stepper. This object requires steps-per-revolution from the motor and a port number to which the motor is connected as parameters.

This library is offered under a free GPL license for those who want to use it that way. We try hard to keep it up to date, fix bugs and to provide free support. If this library has helped you save time or money, please consider donating at or here:

The Ardunio motor drive shield is useless really,as one it don't put enough current to drive anything bigger than a matchbox,,and also there is no software library for it either,which makes programming it to do anything other than the most basic functions very hard..I have tried to write a library for it,and everything seemed fine but when i added it to a simple sketch nothing happened.I kinda tried to reverse engineer the AF motor library for the Adafruit motor shield,but its a bit complicated for me and i may try to write a simpler library for it one day soon.I The thing that makes it hard is that the Adafruit shield uses a shift register instead of a simple H-bridge pin to pin interface like the Ardunio shield does.I have to brush up on shift registers and study the data sheet for the 74hc595 to try and reverse engineer but it may be too hard !for me anyway. i consider myself an intermediate in C C++.

@karotu: No, the L298N motor drive is not the same as the Adafruit motor driver. It is a more basic board, I believe there is no library for it, you have to work with the pins directly. Here is an example Arduino sketch that shows how to use this motor driver: -Modules-L298N-Dual-H-Bridge-Motor-Controll/step4/Arduino-Sketch-Example/. To use my code with it, you will need to write a new motor driver class that controls the motors accordingly.

Hi Miguel 

Can I use HC-04/Bluetooth sensor in place of BT2S .

Or I have to install new library completable with HC -04.is there any change in connections coz it has two extra pins(KEY and STATE).

Yep, especially Panasonic's control scheme is basically the best there is. Still, ordered R8 + 24-50 STM for 1190 brand new - grey import to UK. One cannon argue with that price + the library of affordable EF primes of which EF 85mm F1.8 USM is possibly my most favourite lense of all time, as I took the most beautiful family and friends portraits with this lens.

To be able to adapt the huge second hand EF library and have them working natively on RF mount, actually even better thanks to more advanced AF technology with focusing plain aligned with sensor plain on mirrorless, that is the biggest incentive why to go Canon and not other mirrorless. The adapter is not bulky at all and quality 3rd party ones, like this one I tested myself , go for peanuts and work flawlessly. The linked one has solid metal build, and even detachable tripod foot for heavier lenses and is weather sealed with a gasket at the mount, thus the combos could be weather sealed. e24fc04721
