How does an Arduino Motor Shield work?

How does an Arduino Motor Shield work?

The Arduino Motor Shield is based on the L298 (datasheet), which is a dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors. It lets you drive two DC motors with your Arduino board, controlling the speed and direction of each one independently.

How do you attach a motor shield to Arduino Nano?

The adapter can be connected by plugging a 2.1mm centre-positive plug into the Arduino’s board power jack on which the motor shield is mounted or by connecting the wires that lead the power supply to the Vin and GND screw terminals, taking care to respect the polarities.

How do you make a motor driver shield?

Components Required

  1. Motor Driver IC L293D -2.
  2. 74HC595 Shift Resistor -1.
  3. 104 capacitors -5.
  4. 3 Pin Terminal Block -5.
  5. Push button -1.
  6. SMD LED -1.
  7. 1k – resistor -1.
  8. PCB (ordered from JLCPCB) -1.

How are the pins on the Arduino shield used?

There are pins on the Arduino that are always in use by the shield. By addressing these pins you can select a motor channel to initiate, specify the motor direction (polarity), set motor speed (PWM), stop and start the motor, and monitor the current absorption of each channel . The pin breakdown is as follows:

How many channels does the Arduino motor Shield have?

The motor shield has 2 channels, which allows for the control of two DC motors, or 1 stepper motor. It also has 6 headers for the attachment of Tinkerkit inputs, outputs, and communication lines. The use of these pins is somewhat limited, and therefor not covered in this tutorial.

How do you control a motor with Arduino?

To control a motor using the Arduino Motor Shield, first plug the motor’s positive (red) wire into Channel A’s + terminal on the motor shield, and the motor’s ground (black) wire into Channel A’s – terminal on the shield. An external power supply is not always necessary, but it drastically improves the motor’s performance.

Can You Power Arduino shield with stepper motor?

Wiring diagram for Arduino Motor Shield Rev3 with stepper motor. The connections are also given in the table below. It is possible to directly power the shield from the Arduino, but this is not recommended. When the stepper motor draws too much current, you can damage both the shield and the Arduino.
