What pins does Arduino Motor Shield use?
While using this shield 6 analog Pins (which can be used as digital pins too), pin 2 and pin 13 of arduino are free. In the case of using Servo motor, pins 9, 10, 2 are in use. In the case of using DC motor, pin11 for #1, pin3 for #2, pin5 for #3, pin6 for #4 and pins 4, 7, 8 and 12 for all of them are in use.
How to connect Arduino Motor Shield?
To connect your external power supply, connect the positive (red) wire from the power supply to the "Vin" terminal, and the ground (black) wire to the "GND" terminal. Finally, upload the code to control the Motor Shield to the Arduino.

How do you use Adafruit motor shield v2?
DC motors are used for all sort of robotic projects. The motor shield can drive up to 4 DC motors bi-directionally. ... Include the required libraries. Make sure you #include the required libraries.Create the Adafruit_MotorShield object.Create the DC motor object. ... Connect to the Controller. ... Set default speed. ... Run the motor.
What are the difference of Arduino motor & Arduino Motor Shield?
A motor shield is a circuit board with connections on it that contains a motor driver chip that drives motors. A shield is convenient since you can just plug it in to your Arduino and wire the motors direct to it, but it lacks the flexibility of a raw driver chip which you can wire up precisely as your project demands.
Which microcontroller is used for Arduino Uno?
ATmega328PArduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset button.
How many stepper motors can an Arduino control?
The Arduino Mega 2560 can control 14 stepper motors: May be but it can control a lot more than simply 14. Remember it only takes 2 outputs to control a motor so divide the number of output by two to get the maximum number without adding more outputs from a port expander.
How do you run a stepper motor with an Arduino L293D IC?
Start by connecting 5V output on Arduino to the Vcc2 & Vcc1 pins. Connect ground to ground. You also need to connect both the ENA & ENB pins to 5V output so the the motor is always enabled. Now, connect the input pins(IN1, IN2, IN3 and IN4) of the L293D IC to four digital output pins(12, 11, 10 and 9) on Arduino.
How do I use a L293D motor driver with Arduino?
Place the L293D in the center of the breadboard, with half of the pins on either side of the breadboard. Connect 5V to Enable 1 , Vss , and Vs on the L293D. Connect digital output pins (we're using 6 and 7) to input 1 and input 2 on the L293D. Connect your Arduino's GND to both GND pins on the same side of the L293D.
How to connect Adafruit motor shield to Arduino uno?
Plug the shield into the Arduino and connect a stepper motor to motor port 2 - unlike DC motors, the wire order does 'matter'. Connect to the top two terminal ports (coil #1) and the bottom two terminal ports (coil #2). If you have a bipolar motor, do not connect to the middle pin (GND).
What is a VIN jumper?
You need a VIN jumper if you want to power your motors from the Arduino VIN pin. If you are supplying power to the External Power terminals on the shield, you must remove the VIN jumper. The jumper is a tiny black part that should be in your parts bag.
What is H-bridge circuit?
The H-bridge is an electronic circuit that looks like the letter H. An H-bridge is used to drive a load, such as a brushed DC motor, in both directions. And it controls the flow of current to a load.
