Does L293D work with PWM?
You can provide it with “PWM” pulse width modulation at variable duty cycles. You aren’t writing an analog value to the pins on the l293d. Analog write on the arduino is creating a pwm signal. The l293d only understands logic high and low.
Can L293D control 12V motor?
Wiring a L293D Motor Driver IC to an Arduino
They are rated for 3 to 12V. Therefore, we will connect the external 5V power supply to the VS (Vcc2) pin. Next, we need to supply 5V to the logic circuitry of the L293D. Connect the VSS (Vcc1) pin to the 5V output on the Arduino.
How do you use a DC motor with Arduino with L293D?
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. Finally, connect output 1 and output 2 of the L293D to your motor pins.
How many DC motors can be controlled simultaneously single L293D IC?
two DC motors
The L293D is a 16-pin Motor Driver IC which can control up to two DC motors simultaneously, in any direction.
How does L293D motor driver work?
L293D IC is a typical Motor Driver IC which allows the DC motor to drive on any direction. This IC consists of 16-pins which are used to control a set of two DC motors instantaneously in any direction. It means, by using a L293D IC we can control two DC motors. As well, this IC can drive small and quiet big motors.
What is L293D used for?
The L293D is designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V. Both devices are designed to drive inductive loads such as relays, solenoids, DC and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications.
How does L293D control speed?
To control the speed of the motor :
The speed is set by using an analogWrite to the enable pin. Speed of the motor can be changed by changing the value in “analogWrite”, The motor spins at a maximum speed if the value in analogWrite is set as 255.
How do I get 12V output from Arduino?
To get a 12V output from an Arduino Uno Board you need to use the Vin and GND pin as terminals. Vin would give the maximum voltage being provided to the board ( if board is supplied 9V then Vin would supply 9V and likewise).
Can the L293D run 4 motors?
L293D Motor Driver & 74HC595 Shift Register
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. The shield offers total 4 H-Bridges and each H-bridge can deliver up to 0.6A to the motor.
Can I connect 4 motors to L293D?
So the answer is no, it won’t allow the independent control of four motors, but you could possibly connect two in parallel to each output, depending upon the application. If you want to use 4 DC motors with L293D, you will not be able to control their direction (polarity across motors).
How does L293D control motor speed?
How does Arduino control DC motor speed?

Can L293D handle 9V?
The 9v battery can supply a voltage of 9V. The L293D can work with 4.5V to 36V as you can read in the datasheet. The dc motor can cope with a voltage of 6V.
How do you code a L293D motor driver?
1.3 L293D IC Pin Out
Pin 2: Input 1, when this pin is HIGH the current will flow though output 1. Pin 3: Output 1, this pin is connected with one terminal of motor. Pin 6: Output 2, this pin is connected with one terminal of motor. Pin 7: Input 2, when this pin is HIGH the current will flow though output 2.
How does a L293D work?
Can a 5V relay handle 12V?
12V will definitely damage the relay board. This 2 channel relay board requires about 200mA at 5V with both relays energized.
Is it safe to power Arduino with 12V?
The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.
Why L293D IC is used?
How many power supplies does the L293D use?
The L293D IC has two power supply pins. Pin 16, VCC1, is to power the IC itself, ei., its internal logic.
Why do we use L293D?
How does PWM control speed of DC motor?
In this paper, to control the speed of DC motor using Pulse Width Modulation (PWM) method. Microcontroller AT89S52 is used to generate PWM. L293D IC is used to drive the motor which is made up of two H-Bridge. 555 IC is used with opto coupler to sense the speed of DC motor.
Why PWM is used in DC motor?
Motors as a class require very high currents to operate. Being able to vary their speed with PWM increases the efficiency of the total system by quite a bit. PWM is more effective at controlling motor speeds at low RPM than linear methods.
How many pins is L293D?
16 Pins
L293D has 16 Pins in total which are as follows: Pin # 1 is Enable 1 which is used to turn ON or OFF the first H-bridge. Pin # 2 is Input1, which is the first Input for Motor1. It should be connected with a Microcontroller.
What pins does L293D use?
L293D has 16 Pins in total which are as follows:
- Pin # 1 is Enable 1 which is used to turn ON or OFF the first H-bridge.
- Pin # 2 is Input1, which is the first Input for Motor1.

- Pin # 4 & 5 are GND, so they should be connected to 0V or ground.
Can you use a MOSFET as a relay?
A MOSFET relay offers superior performance to an electromechanical relay in many applications. It is a solid-state device that replaces a coil-activated mechanical switch with an optically isolated input stage driving a MOSFET.
