Arduino boards are based on a microcontroller equipped with a set of I/O ports. The maximum power provided by an Arduino output is about 40mA and the maximum operating voltage of the I/O port is 5V. Although it is enough to supply e.g. LED diodes, the power supply directly from Arduino may turn out to be insufficient if you want to supply one or more motors or servos.

However, this issue can be easily solved thanks to dedicated Arduino Shield modules which contain the necessary equipment that enable smooth control of operating parameters of electric motors with power consumption up to 50A.
Connecting a dedicated module makes it easier to link and control motors and servos (including reverse rotation direction). Most of our Arduino Shield boards for motor and servo control are equipped with integrated circuits such as L293D, L298P and DRV8835 which use key transistors combined in an "H" bridge. Switching the operating status of individual transistors enables to change the polarity of the motor power supply voltage, and thus, the rotation direction of the motor shaft indicated by LEDs. Arduino Shield modules are equipped with high current efficiency power lines and variable operating voltages, so you can choose either the module appropriate for 6V, 12V, 24V motors or any other customized supply voltage. Additionally, thanks to using motor and servo controllers such as Arduino Shield modules, you prevent your Arduino board from any potential damage - shields are equipped with built-in thermal and under-voltage protections that also preserve your motors and servos.
Shield manufacturers like Cytron provide free software that can be directly uploaded to your Arduino and thanks to that you can control your motors. The source code enables simple implementation of motor control - for example, you can easily check the motor temperature and if it is necessary, you can manually change the rotation direction, no matter what are the guidelines in the program code. Arduino Shield boards dedicated to DC and servo motor control can be also applied to control contactors, relay coils, LED lighting and stepper motors. Arduino Shield servo and motor controllers will help you construct CNC machines, robots and other electric vehicles with a wide range of control capabilities.
