Arduino Shield - motor controllers

Comprehensive motor control modules that don't take up much space

Selecting a dedicated pad simplifies the connection and control of motors and servos, including reversing the direction of rotation. Most of our Arduino Shield boards for motor and servo control are equipped with such integrated circuits as L293D, L298P or DRV8835, which in their structure use keying transistors connected in an "H" bridge. Switching the operating state of individual transistors allows to change the polarity of the motor supply voltage, and thus - the direction of rotation of the motor shaft, which is signalled by LEDs. Arduino Shields are equipped with power lines with high current efficiency and different operating voltage, so you can choose the appropriate one to control the motors that require 6 V, 12 V, 24 V or other non-standard values of the supply voltage. Moreover, by using motor and servo controllers in the form of dedicated Arduino Shields you protect the main Arduino board from possible damage. Shields have built-in thermal and undervoltage protection, which also protects the controlled motors and servos.

What else is worth knowing when buying motor control overlays?

There are so many different Arduino boards out there that if you're still at the very beginning of your adventure with electronics, it's easy to get lost in them. The following tips may be helpful for you! You surely know that in order to create a fully remote controlled moving machine, you need to buy motors and motor controllers. However, remember that you should always carefully check the parameters of the Arduino board you have before buying the additional equipment. Then check the parameters of the shield you are interested in: pay particular attention to the pinout of a particular shield, its operating voltage, and the software library that the shield uses. The number of channels is also important - there are single-channel, dual-channel, and even sixteen-channel Arduino Shields. Remember that the more channels the hardware has, the more engines it can support simultaneously!

Modules with embedded software

Many manufacturers of Arduino Shield, such as Cytron, provide free software that you can load directly onto your Arduino and control your motors. The source code allows you to easily implement motor control. You can easily check the motor temperature and manually change the direction of rotation by bypassing the instructions in the program code as needed (remember though: always read the instructions first). Arduino Shield Boards designed to control DC motors and servos can also be used to control contactor and relay coils, LED lighting, and stepper motors. With the Arduino Shield programmable microcontrollers for servos and motors, you can build CNC machines, robots, and other electric vehicles with extensive control capabilities.
