In this blog post we will see how to use a L293D IC to drive a DC motor in.

The speed of the DC motor (both directions) is controlled with the 10k potentiometer which is connected to analog channel 0 (A0) and the direction of rotation is controlled with the push button which is connected to pin 8 of the Arduino UNO board. If the button is pressed the motor will change its direction directly. Software antrian.
The L293D driver has 2 VCCs: VCC1 is +5V and VCC2 is +12V (same as motor nominal voltage). Pins IN1 and IN2 are the control pins where: IN1 IN2 Function L H Direction 1 H L Direction 2 L L Fast motor stop H H Fast motor stop As shown in the circuit diagram we need only 3 Arduino terminal pins, pin 8 is for the push button which toggles the motor direction of rotation. Pins 9 and 10 are PWM signal outputs, at any time there is only 1 active PWM, this allows us to control the direction as well as the speed by varying the duty cycle of the PWM signal. The active PWM pin decides the motor direction of rotation (one at a time, the other output is logic 0). Arduino code: Arduino code is below.
A motor driver is an integrated circuit chip which is usually used to control motors in autonomous robots. Motor driver act as an interface between Arduino and the motors.
The most commonly used motor driver IC’s are from the L293 series such as L293D, L293NE, etc. These ICs are designed to control 2 DC motors simultaneously. L293D consist of two H-bridge. H-bridge is the simplest circuit for controlling a low current rated motor. We will be referring the motor driver IC as L293D only.
L293D has 16 pins. The L293D is a 16 pin IC, with eight pins, on each side, dedicated to the controlling of a motor. There are 2 INPUT pins, 2 OUTPUT pins and 1 ENABLE pin for each motor. L293D consist of two H-bridge. H-bridge is the simplest circuit for controlling a low current rated motor. - Pin Characteristics • 1 - Enable 1-2, when this is HIGH the left part of the IC will work and when it is low the left part won’t work.• 2 - INPUT 1, when this pin is HIGH the current will flow though output 1• 3 - OUTPUT 1, this pin should be connected to one of the terminal of motor• 4,5 - GND, ground pins• 6 - OUTPUT 2, this pin should be connected to one of the terminal of motor• 7 - INPUT 2, when this pin is HIGH the current will flow though output 2• 8 - VCC2, this is the voltage which will be supplied to the motor.
• 16 - VCC1, this is the power source to the IC. So, this pin should be supplied with 5 V• 15 - INPUT 4, when this pin is HIGH the current will flow though output 4• 14 - OUTPUT 4, this pin should be connected to one of the terminal of motor• 13,12 - GND, ground pins• 11 - OUTPUT 3, this pin should be connected to one of the terminal of motor• 10 - INPUT 3, when this pin is HIGH the current will flow though output 3• 9 - Enable 3-4, when this is HIGH the right part of the IC will work and when it is low the right part won’t work. Diskografiyu skrillex njhtyn album. Why 4 grounds in the IC? The motor driver IC deals with heavy currents. Due to so much current flow the IC gets heated. So, we need a heat sink to reduce the heating. Therefore, there are 4 ground pins.
When we solder the pins on PCB, we get a huge metalllic area between the grounds where the heat can be released. Why Capacitors? The DC motor is an inductive load. So, it develops a back EMF when supplied by a voltage. There can be fluctuations of voltage while using the motor say when suddenly we take a reverse while the motor was moving in some direction.
At this point the fluctuation in voltage is quite high and this can damage the IC. Thus, we use four capacitors that help to dampen the extreme variation in current.
