Bro I followed all the steps you mentioned and made the project with Arduino Uno. Controlling a DC motor from computer with USB Interface. We think this shield would be a good start for beginners because of its versatility for its price range. Arduino Motor Shield Tutorial Dc Motor >>>CLICK HERE<<< 2 DC motors in a small RC car body - Arduino UNO - Seeed Motor Shield and hook up wire. - Pin number 2 is to control the motor and according to my sketch it is pin number 2 in Arduino aswel. The range of voltage supported by the DC motor. 13 | DC Motor DC motors rotate when current is applied and are commonly used in a wide variety of applications from robot wheels to cooling fans. In this project, we will focus on the more advanced L298N Motor Driver and see Arduino DC Motor Control using L298N Motor Driver using PWM technique. The L293D is a 16-pin Motor Driver IC which can control a set of two DC motors simultaneously in any direction. Apart from these techniques, pulse width modulation is the effective way to implement motor speed control. Dc motor is driveby using PWM technique and then using encoder to sensethe rpm of DC motor. The pins are made compatible with Arduino which is easy to use. How to Use Arduino L293D Motor Driver Shield? While using this shield 6 analog Pins (which can be used as digital pins too), pin 2 and pin 13 of arduino are free. Pins 2 and 7 of L293D are inputs of drivers associated with motor 1. In this project, the speed of a DC motor is controlled using the same principle. The output enable of the L293D is directly connected to PWM outputs of the Arduino. You don’t have to spend a lot of money to control motors with an Arduino or compatible board. The motor is operated in four quadrants viz, clockwise; counter clock-wise, instantaneous forward brake, and instantaneous reverse brake. Moreover, most DC motors need more power than the Arduino could provide. Motor Driver Module: Here, L293D Motor Driver Module is being used to drive the motors of the robot. 2A, 1420 rpm Shunt type single phase. L293D motor driver. This module allows us to control the speed and direction of the motors. I intend to do so by powering them by a separate 3xAA battery pack (provided with the Mr. MPU6050 is an Accelerometer & Gyro sensor combined in a single chip. It has 16 pins and it can control two DC motors at a time. Use potentiometer to control the speed. The ESP8266 (the new IoT trend for makers) can only provide a maximum of 12 mA [2].
