What is the function of motor driver shield?
The Arduino Motor Shield allows you to easily control motor direction and speed using an Arduino. By allowing you to simply address Arduino pins, it makes it very simple to incorporate a motor into your project. It also allows you to be able to power a motor with a separate power supply of up to 12v.
How many DC motors can be connected to a single L293D motor driver?
4 DC motors
L293D shield is a driver board based on L293 IC, which can drive 4 DC motors and 2 stepper or Servo motors at the same time. Each channel of this module has the maximum current of 1.2A and doesn’t work if the voltage is more than 25v or less than 4.5v.
How many pins does a l293 motor driver have?
16 pin
The L293D is a 16 pin IC, with eight pins, on each side, dedicated to the controlling of a motor.
What pins does Adafruit Motor Shield use?
The shield uses the SDA and SCL i2c pins to control DC and stepper motors. On the Arduino UNO these are also known as A4 and A5. On the Mega these are also known as Digital 20 and 21.
What is Adafruit Motor Shield?
Description. The original Adafruit Motorshield kit is one of our most beloved kits, which is why we decided to make something even better. We have upgraded the shield kit to make the bestest, easiest way to drive DC and Stepper motors. This shield will make quick work of your next robotics project!
What is H bridge circuit?
From Wikipedia, the free encyclopedia. An H-bridge is an electronic circuit that switches the polarity of a voltage applied to a load. These circuits are often used in robotics and other applications to allow DC motors to run forwards or backwards.
How many DC motors can a shield drive?
L293D shield is a driver board based on L293 IC, which can drive 4 DC motors and 2 stepper or Servo motors at the same time. Each channel of this module has the maximum current of 1.2A and doesn’t work if the voltage is more than 25v or less than 4.5v.
What are the features of the Arduino motor shield?
The motor shield has quite a few features such as current measuring and the ability to drive a single stepper motor. A tutorial for the Arduino Motor Shield with a simple project. The Arduino Motor Shield is a shield that lets you control various loads that a typical Arduino pin cannot drive.
Is the l293d motor driver shield compatible with Arduino Mega?
Arduino’s L293D motor driver shield is compatible with Arduino Mega and UNO. The shield can be fitted on top of the Arduino board. In such cases, six analog pins including pins 2 and 13 remain free for use. Pins 2, 9, and 10. The DC motor can be connected to any of the four motor ports.
Do you need a power supply for a motor shield?
The motors attached to the motor shield need an ample power supply. By using the USB connection, the current will often be limited to 500mA or 1 amp. Many motors will draw more current than the amount the USB source can supply. To reduce the risk of possible damange to a usb port an external power supply should be used.
