C. L193D IC
D. L263D IC
Explanation: The Motor Driver is a module for motors that allows you to control the working speed and direction of two motors simultaneously .This Motor Driver is designed and developed based on L293D IC.
L293D is a _______ Pin Motor Driver IC
Explanation: L293D is a 16 Pin Motor Driver IC.
This is designed to provide bidirectional drive currents at voltages from ___________.
A. 5 V to 25 V
B. 5 V to 36 V
C. 6 V to 36 V
D. 6 V to 30 V
Explanation: This is designed to provide bidirectional drive currents at voltages from 5 V to 36 V.
How many input pins are there in each motor?
Explanation: There are 4 INPUT pins, 4 OUTPUT pins and 2 ENABLE pin for each motor.
Pin 4/5 is used for?
A. this pin is connected with one terminal of motor
B. this pin is HIGH the current will flow though output 1
C. GND pins
D. this pin is connected with one terminal of motor
Explanation: Pin 4/5: GND pins
Pin 15: Input 3, when this pin is HIGH the current will flow though output 3.
C. Can be true or false
D. Can not say
Explanation: Pin 15: Input 3, when this pin is HIGH the current will flow though output 3.
Jumpers are preset on the __________ of module.
A. Enable 1-2 pins
B. Enable 3-4 pins
C. Both A and B
D. None of the above
Explanation: Jumpers are preset on the Enable 1-2 and Enable 3-4 pins of module, so that motor will be enabled and work at maximum speed.
What is the use of the EN1_2 pin?
D. Power input
Explanation: The EN1_2 pin is used to enable a part of the IC which controls a segment of the motors connected to it. They accept 5V usually if the module has a 5V rating.
What will happen if we supply a voltage of 250 kV to the Vcc of the L293D module?
A. Damage is caused
B. Module will shut down
C. Module will not respond for the time the voltage is applied
D. Module will function normally
Explanation: The L293D modules are mostly built to work on a voltage of approximately 5V. Any voltage lower than that and the module will not be able to power on, but however any voltage significantly above that and the sensor may suffer permanent damage.
What is the use of the Vcc2 pin?
D. Power input
Explanation: The Vcc2 pin is used to input a high amount of voltage and is not internally used by the IC. It is there to power the motors attached to it. This way the same IC can be used for controlling higher powered motors.
