could you connect 2 L298N to 1 Esp32 for 4 motors?

[@sheriftamer6486]

Yeah but the best way is to c9nnect on motor drive for 4 motors i did it with 4 12v dc motor and worked perfectly

[@draculla123]

I have same doubt

[@Omar-AlAni-78]

@@sheriftamer6486 never worked for me. Seems one L298N can handle correctly 2 dc motors only. 4 motors seem to be too much for one L298N.

Hi, i have a problem with the librery, is not working, im ussing the arduino IDE 2.3.3 and if i run the esp32 2dc motors example, without touching anything of the code, it display errors about "'ledcAttachPin' was not declared in this scope; did you mean 'ledcAttach'?" and 'ledcSetup' was not declared in this scope

[@Kub_43]

For anyone that faces the same problem, the library is compatible until version 2.0.17, beacause espressif made changes in version 3 to the pwm functionallities. it would be cool to see this library in versions > 3 tho, it simplifies everything

[@arseniusdavin183]

[@naufalchoirulanandaa]

Sir, why with 12v voltage and 4 dc motors my L298N module makes noise and the motors don't rotate?

Is it possible to use 2 L298N modules to control 4 DC motors using ESP32? I tried to modify the code but i really get stuck. I want to control them by wifi. With 2 motors and you library works really good, but we always want more :) thanks in advance!

Yes if you have enough pins. Just define different ping and different object name.

Hello Ahmad thank you for the video I would like to know what should I have to do for both Motors to run simultaneously in clockwise or anti-clockwise cause I am designing a robot which will have 2 DC Motors however the robot has to move Forward , Backward, Turnleft and Turnright. I am using ESP32 and L298N

[@robojax]

Hello, I believe I have explained every line and what they do. so I would suggest watching the video 2 or 3 times until you understand it. Just see which line in the code makes the motor to run make copy of the same line in the line below it and change the value to make the other motor rurn. or may be watch this video kzbin.info/www/bejne/rZ-YdWqgZt6Vrrs and learn which line controls a motor.

Hi Im doing Up my sons ride on car and need to run two motors off the back and one motor for steering.. I have the ESP32 and the Dual L298N Motor driver model too .. any pointers would help

[@robojax]

Hi, this should work. just identify the pins. check or test be lifting the car and turning it ON. using whatever controller you have try going forward and se which wheels rotate. then turn left and check which motor rotate and the same for right turn. I am not sure if the car has servo to physically turns the wheel or just by controlling the each motor it rotates. My point is to see if 4 motor is used when running the car or just two sets run together. this can be checked to see if two L298N is used or 1. here an one of 4 videos on a smart car kzbin.info/www/bejne/gHXKgIyBpMSth5o using L298N.
