The Arduino Motor Shield is depending on the L298 (datasheet) , that could be a dual full-bridge driver created to drive inductive loads for example relays, solenoids, DC and stepping motors. If your motor call for more than 9V we recommend that you separate the power lines of the shield at the same time as the Arduino board on which the shield is mounted. 1mm center-positive plug into the Arduino's board energy jack on which the motor shield is mounted or by connecting the wires that lead the energy provide to the Vin and GND screw terminals, taking care to respect the polarities. An external energy provide connected to this pin also offer you energy to the Arduino board on which is mounted. You can also measure the current absorption of each motor, among other functions. To maintain away from attainable harm to the Arduino board on which the shield is mounted, we reccomend employing an external power supply that supplies a voltage between 7 and 12V. The shield is Tinker Kit compatible, which indicates you can rapidly create projects by plugging Tinker Kit modules for the board. This really is attainable by cutting the"Vin Connect"jumper placed on the back side of the shield. By cutting the"Vin Connect"jumper you make this a dedicated power line for the motor. The existing draw for the motor supply is often than the USB can give. The Arduino Motor Shield need to be powered only by an external power supply. Because the L298 IC mounted on the shield has two separate power units, 1 for the logic and 1 for the motor supply driver. External (non-USB) energy can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2. It lets you drive two DC motors with your Arduino board, controlling the speed and path of each one independently. The absolute limit for the Vin in the screw terminals is 18V. GND Ground on the screw terminal block. The power pins are as follows: Vin on the screw terminal block, is the input voltage for the motor connected towards the shield.
