Hi, Im also connected the 4-wire bipolar motor with l293d driver. I tied all the 4inputs to the ground, and its corresponding output are all shown as Low. While im interfacing the motor with the IC, it got burnt. I dont know why it is happening. Two Ics were burnt. Please clarify me to solve the issue, and please help me to run the bipolar stepp
i had this circuit for controlling 2 wiper motors using a motor driver - l293d and relay i used l293d to control the direction of motor but it only provides small amount of current, so it can only drive small motors like DC. when i tried to control the wiper motor, it does worked but can't make it rotate. i was thinking that it's because (...)
You can go with l293d Motor Driving ic
I am using 4011 CMOS as touch switch to control my microcontroller that is linked to motor driver l293d as on/off. When I touch for the first second, the motor will activate for 2seconds. It works fine if I am touching it for more than 2 seconds.Let's say,if I touch for 3seconds, then the motor will activate for 3 seconds. Do u have any ideas
I'm trying to make a 3 axis bipolar stepper driver and I think using l293ds and Arduino is the best cheapest option. I have seen people using grbl to run their steppers easily but with grbl they have used expensive Easy drivers or Adafruit motor shield. I can't use them and I want my motors to run from H-bridges only. What can I do to make (...)
yes u can use motor driver ic like l293d . - - - Updated - -
l293d is Bipolar stepper motor driver. I need Unipolar Stepper motor driver.
u will need to interface motor driver IC that is l293d and you will get reference from follow and images as follows
Hello Guys...need your help to confirm if we can directly replace UDN2993B dual h-bridge motor drivers --> with l293d...Also appreciate much if anybody can recommend a replacement IC for UDN2993B ? Tthanks in advance.
Hi , I ordered online for stepper and its driver , I got the stepper motor (attached the snapshot1 ) and HBridge for the same (snapshot2) . I do not know the pin details of stepper motor to integrate with Controller .. Can you pls suggest how can I connect this with the l293d brdige and 8051 controller . 92527 [
Use l293d motor driver IC. U can directly give MCU output as input to this and it will drive the motor. U can also use this in Push pull mode, configure it as H-Bridge driver. 88138 On the other hand, u can use power mosfet in H bridge configuration for motor on off. And also can provide PWM to mosfets to control the speed
What is the voltage you are giving to l293d and the 2 motors? How long do you want to run the motors? How much current does each motors draw? Are you going to charge the battery without removing it from the circuit? The battery can only give 1.3A continuously for 1 hour. If one motor draws 1A to run then the motor runs for 1.3 hrs. The battery i
Hi; Porbably, sudden current increase because of the motor windings cannot be compansated by your power supplys. Place elco caps close to l293d, and also some ceramics in parallel also. take care to place as close as to l293d device pins. Check also power line from your power supply to motor driver, that power line on PCB should be thick (...)
hi everyone i want to do one project like i want to interface dc motor by using the driver ic l293d with microcontroller 89c51 RD2 IC by using the concept of pwm can anyone help in that....
plz help me,i m using l293d ic to drive 12V dc geared motor , but i m getting very low output voltage of only 1.5V , even in input voltage i give 12V n digital input by microcontroller ,so plz tell me how to get 12V at otput
By using the two separate sections of the 74139 allow us to use each two bits of four available on the encoder/decoder circuit and give us two groups for total of four combinations each. One group to be used for the motor drive. The motor section need to comply with the logical status of the l293d driver 00 = Motor stop 01 = Motor clockwise 10 =
I am taking input from serial port to pic and connecting the output to l293d motor driver,its working good.but when I use the outputs of l293d by connrcting motors(dc 12v) pic gives random serial port code is : #include <16f877a.h> //processor declaration #use delay(clock=20000000) //cryst
Are you using a stepper or DC motor in your design? Here are a few tutorials and example projects using the l293d: l293d Dual H-Bridge Motor driver L293 Mo
which IDE?? ok use a toy car with DC motor.. use l293d motor driver for driving the motor... Use HT12E for transmitter and HT12D for receiver... and program the controller to run the robot.......
can you go for l293d or L298.. it will be simple for you.... if you want 74ls series then post the circuit so that we can comment.....
you need l293d motor driver circuit and the rest is your programming skills for pwm...........
i have tested motor driver ic separately,,,, according the i have connected all the pins of l293d except the data input pins as shown in diagram,, when i
hello every one. m trying 2 build a line follower robot by the use of pic16f628a controller. the idea is the IR sensor(QRD1114) will seance the path n according to the it will give the signal to the controller. by seance of the path controller has to give the signal to the DC motor driver(l293d) n thsi has to rotate the motor.... but the m
you can use l293d or L298 driver for your replacement... you can compare its working and requirement in the pdf....
could you simulate it with l293d instead of the IC you are using....
12d is decoder and l293dis used for motor driver. So they are connected to controller. do you want to interface each other or interface both to controller
Hi there.. I am student from Malaysia.. Currently i'm doing my final year project with my partner about wifi spy robot.. we manage to construct the circuit and do the pic programming..(PIC16F877A) our problem is that the voltage from pic to the l293d(motor driver) is very low..we getting 1v instead of 3v.. Hope you guyz can help us on how to o
If you can program and make a program for MCU then you do not hawe a problem.You need a 2 servos 360' or GM9 redutors from solarbotics,linksys WRT54 Wi-Fi router,becose with linux you hawe a 232 prptocol in it/can comunuicate with MCU simple / IP camera to see on PC and motor driver-ex. l293d
as technodict said i am not using any mc . i am planning to connect Q1 Q2 ,Q3,Q4 directly to l293d motor driver. Then You must use pull down resistors at lets say more or less 10 to 47 Kohms.
Hey guys, I am using Multisim 10 for my schematic design. I need a driver for my DC motor but I see that MS10 does not have a component for l293d While creating this component I want to have it for both Simulation and Layout.. Can someone pls tell me where I can find the VHDL model for this IC Thanks for your time...
Hi.I'm new member here.I'm facing problem with controlling the DC geared motor rotating time as using C language programming. How to i delay the motor operating time till 5seconds? Below is the example of backward motor operating method as i use motor driver l293d. en12 = 1; in1 = 0;
Hello guys. I have to use l293d (motor driver) with PIC16F628. Have got only 1 question Q) Does the digital (5V) and analog (12V) grounds have to be common and all the four ground pins have to be connected to it. Or two ground pins are for digital supply while the other two are for analog supply and digital and analog grounds have to be kept sep
Hi, The motors are 6V powered Regs, Mike So why do you need 3.3V driver??? Just use l293d @ 5V, it will give you 3.3 to the Motors.
hi, I am doing a project in controlling DC motor with l293d in both direction, if I send high pulse to either one driver it will turn in a direction, if I send both driver high pulses, according to the data sheet the motor will have fast stop, but I need to know how long this situation can stand? I afraid the L293 or my motor will burn.
wht motor u want to drive and tell its ratings. go for l293d. I think u can make driver ckt using some power transistors
