To power itself it requires 5V voltage through VCC1 and can deliver up to 12 volts through VCC2. In this tutorial I will show you how to use this motor driver with Arduino in controlling a simple DC motor and a 28BYJ-48 unipolar stepper motor. How does the recent Chinese quantum supremacy claim compare with Google's? As the shield comes with two L293D motor driver chipsets, that means it can individually drive up to four DC motors making it ideal for building four-wheel robot platforms. Thankyou for your answer made a lot of doubts and misconceptions clear. B) Use the L293D chip to drive the motor. The L293D Motor driver shield is one of the best way for controlling DC, Servo and Stepper motors especially if you are using Arduino UNO or MEGA in projects like robotics and CNC. The bit we really care about in all of this is the 2 input pins per motor that do this logic and these, more importantly for our needs, can be controlled from the Arduino board. It means if you want to operate a motor at 9V then you need to provide a Supply of 9V across VSS Motor supply.The maximum voltage for VSS motor supply is 36V. Logic 01 and 10 will rotate it in clockwise and anticlockwise directions, respectively. Pin 16, VCC1, is to power the IC itself, ei., its internal logic. The L293D has two +V pins (8 and 16). is it possible to read and play a piece that's written in Gflat (6 flats) by substituting those for one sharp, thus in key G? Pin 8 is the motor power and can vary between 4.5 and 36V. analogWrite(E2, 255); // Run in full speed In its common mode of operation, two DC motors can be driven simultaneously, both in forward and reverse direction.
