![]() ![]() Step 1: Set the address using the dial switch that was introduced in V1.3. Base Shield V2 (optional, it facilitates the connections).What do you need to get started? See the list below: The drive is uses the L298N chip controlled by an Atmel ATmega8L: it can handle current of up to 2A per channel and allows you to use I2C communication ( read more about this chip in the Seeedstudio blog). The Grove – I2C Motor Driver V1.3 (the latest version) is a driver that can be used to control two brushed DC motors or one 4-wire two-phase stepper motor they can be controlled simultaneously at different speeds and directions. How to control a DC motor using an Arduino Motor Driver That is all! You have started a DC motor with your Arduino Motor Shield in just a few steps! You can be proud of yourself. The LED indicator should also flash properly. If this does not happen, check that the code has been uploaded successfully and that the motor is connected correctly. Your motor should now start and move for 1 second, then stop for 1 second, move for 1 second, stop for 1 second again and then form a loop. Motor.speed(0, 100) // set motor0 to speed 100 Step 5: Upload the following code to Seeeduino: // Demo function:The application method to drive the DC motor. Step 4: Install the Motor Shield library (it can be downloaded here, and the guide on the installation itself is available here). Make sure that your connection looks like this: Step 3: Connect the DC motor to channel 0 (OUT1 and OUT2), connect the motor shield to your Arduino and then connect the board to your PC using a USB cable. Step 2: Since you do not need an external power supply for this project, connect MB_EN together with a jumper. Step 1: Set SEN_A and SEN_B and connect the 2 pins that are left with a jumper. Now let’s get down to the basics – what do you need to control a DC motor with your Arduino Motor Shield? The list is quite short: To learn more about the L298 chip, you can visit the Seeedstudio blog. ![]() It allows you to use your Arduino to control the speed and direction of the motor, and even control two DC motors at once (or one stepper motor). The Motor Shield is a special driver module based on the Dual Full-Bridge Drive Chip L298. How to control a DC motor using an Arduino Motor Shield DC motors usually do not have their own polarity (and if they do, then they are marked with + or -), which means that you can easily change the direction of rotation by reversing the wires. And how is this possible? When current flows through the motor, the opposite polarity between the two magnetic fields inside the motor causes it to rotate as long as the current passes through the device. This simple construction is enough to convert DC electrical energy into mechanical energy. A DC motor consists of a stator, armature, rotor and commutator. They are so popular because of their simplicity and efficiency compared to other types of motor. ![]() You may not be aware of it, but you use them every day – they are used in your vacuum cleaner or hair dryer, in elevators and in many other places.
