Note: Digital pins D2, D13, and analog pins A0-A5 are not used by the shield. Output for Servo motor 2, Connect the servo motor pin GND, VCC, SIGNAL respectively Output for Servo motor 1, Connect the servo motor pin GND, VCC, SIGNAL respectively L293D Motor Driver Shield Servo Motor output SL. Output for Stepper Motor 2, connect stepper motors (unipolar or bipolar) with single coil, double coil, or interleaved stepping Output for Stepper Motor 1, connect stepper motors (unipolar or bipolar) with single coil, double coil, or interleaved stepping L293D Motor Driver Shield Stepper Motor output SL. Make sure the jumper is removed from the motor shield. So, at first, you need to connect the power supply to the DC jack on the Arduino, Then connect the motor power supply to the 2-pin External Power Supply terminal block on the shield. If you want to use two separate power supplies for the Arduino boards and motors.

Two separate DC power supplies for the Arduino and motors.

In this condition do not place the jumper on the shield. Now you can turn on the power supply one by one (first the Arduino power supply then the motor power supply). At first, plug in the USB cable, then connect the motor supply to the external Power. If you want to powered the Arduino board through the USB and the motors powered through the DC power supply.

Arduino powered through USB and motors through an External Power Supply pin.

Now you can simply connect the power supply to the DC jack on the Arduino or the 2-pin External Power Supply terminal block on the shield.īut, this method only used when the motor supply voltage is less than 12V. So, Place the power jumper on the motor shield. If you want to provide a single DC power supply for both Arduino and motors. Single DC power supply for both Arduino and motors.It also can be used to the power supply to the Arduino board, it possible by the “Power Supply Selection Jumper”. The shield has a 2-pin terminal block for External Power Supply. The shield comes with a pulldown resistor array, that keeps motors switched off during power-up. If the LED will not ON, it means the power supply is OFF. If the power supply is on the LED is turned on, the motor will work well.

The on-board Power LED indicates the motor’s power supply. It just brought up top for easy to use purpose. This switch works same as the Arduino reset and it is used to reset the Arduino board. The RESET is nothing but the Arduino reset button. The shield has a 74HC595 shift register that extends Arduino 4 digital pins to the 8 direction control pins of two L293D chips.
