The Motor Shield will output 3.3v on the current sense pins when the maximum channel current (2 amps) is reached.

No, it can drive the two motors with the same voltage and PWM duty cycle, but the nature of DC motors is that they don't all spin the exact same speed when given the exact same power, even if they're the same model.

Does exactly what it's supposed to do. You are all set! If you would like to have a single DC power supply for the Arduino and motors. 2 months ago

The motor shield has quite a few features such as current measuring and the ability to drive a single stepper motor. Found a bug in "Here is code for controlling two motors:" Arduino A000079 Motor Shield, R3, 5V to 12V. *Since the “forward” direction of the motors depends on application, for this tutorial "forward" will refer to positive voltage on the + screw terminal on the shield.

I was pumping close to 4A of current through this guy and you could cook an egg on it.Works great with Arduino Uno and Nema 17 stepper motor Is it a toy, a usefull device or a great learning tool - YES In fact my project is simple, i have two push buttons for one motor.






Thorough example code is available for all the sections … By using the Arduino Motor Shield and a potentiometer, the speed and direction of a small motor can be controlled.

Please confirm that you are buying an original Arduino because there were many comments that buyers for other Arduino pieces were made in China.

Hi. Be sure to double check the polarity with a volt meter! The transistor acts like a switch, controlling the power to the motor.

It is recommended that you always use one.To connect your external power supply, connect the positive (red) wire from the power supply to the "Vin" terminal, and the ground (black) wire to the "GND" terminal.Finally, upload the code to control the Motor Shield to the Arduino.Interfacing with two motors is pretty much the same as interfacing with one motor.

Motor shield, yea!!! Please try your search again later.

At the heart of this shield is the L298P dual full bridge driver that can handle up to 3 amps for very short durations or 2 amps continuously per channel.
The Arduino Motor Shield allows you to easily control motor direction and speed using an Arduino. Should be:Great tutorial - how could I use this code to control the motor speed from 0 to full using the potentiometer, without the reverse section ? Current sensing can be useful for robotics applications, such as traction control and determining if the robot is pushing an object. Steps: 1. The Arduino Motor Shield allows you to easily control motor direction and speed using an Arduino.

Works great.
