   please provide joystick library for proteus

   5:20 Shouldn't the 12V power supply ground be also connected to the Arduino ground as well?

4. 

   Can we run 4 motors using this L298N driver?if YES then how can we connect this motors to the L298N???PLZ Plz reply fast..

5. 

   Can i use more than 2 Motors? With the L298N?

6. 

   How do you stop it from veering to one side when it should be moving straight?

7. 

   very nice

   I'm sorry that I can't support you but i have to tell that you would deserve more for these videos.

   Hi, Im trying to build a similar circuit: 24v power supply with a h bridge controller for a 24v servo motor, what I'm worried about its sending the 24V (+) to the VIN Power Pin of the Arduino card (min 06:40).

    Very well explained.The schematics and illustrations are perfrect. Fantastic video

    In case someone connects the motor to A or B with ENB enabled (means motor is not PWM regulated, runs at full speed) with 12V jumper enabled and is surprised nothing happens after turning power on, there is a simple reason. Just connect a wire to 5V out, power on again and then touch either one of two pins, for example IN1 if motor is connected to A, that regulate the rotation direction (forward/backward). The motor will start turning.

    This is a well done video!

    can u send me that c code

14. 

    Can i use L398N analog input

15. 

    All of your videos deserve lot of superlative adjectives. Extremely good quality project and your explanation of theory and the Arduino sketch were precise and clear. May I suggest you do a self balancing two wheel "robot" project and cover PID in detail ?

    Great video and very cool, but i proved the code with my car and the same components and it doesn´t work. Can you tell me any thing for help please?

17. 

    How can c control a 24v, 7A dc motor with same method as discussed in the video?

18. 

    Great video! Very detailed and concise. Thank you.

19. 

    and how did you define the motor speed PWM as 255 when your motor`s 12V with 100rpm
    is there any calculation formula for PWM in motor speed

20. 

    can we connect 3 DC motors to L298 and connect it to Arduino?

    Here is code to control 4 dc motors on tank chassis:
    int rc_pulse1=1; //reading signal from FS
    int rc_pulse2=2;
    int mpwm1=3; //PWM channels for motors
    int mpwm2=4;
    int mpwm3=5;
    int mpwm4=6;

    void setup() {

    pinMode(1,INPUT);
    pinMode(2,INPUT);
    pinMode(3,OUTPUT);
    pinMode(4,OUTPUT);
    pinMode(5,OUTPUT);
    pinMode(6,OUTPUT);
    pinMode(7,OUTPUT);
    pinMode(8,OUTPUT);
    pinMode(9,OUTPUT);
    pinMode(10,OUTPUT);
    digitalWrite(3,LOW);
    digitalWrite(4,LOW);
    digitalWrite(5,LOW);
    digitalWrite(6,LOW);
    digitalWrite(7,LOW);
    digitalWrite(8,LOW);
    digitalWrite(9,LOW);
    digitalWrite(10,LOW);
    }

    void loop() {

    mpwm1=0;
    mpwm2=0;
    mpwm3=0;
    mpwm4=0;
    delay(50);
    rc_pulse1=pulseIn(1,HIGH,25000);
    rc_pulse2=pulseIn(2,HIGH,25000);
    delay(50);
    if(rc_pulse1>1024) {
    mpwm1,mpwm2=map(rc_pulse1,1024,2047,0,255);
    if(mpwm1,mpwm2>0) {
    analogWrite(3,mpwm1);
    analogWrite(5,mpwm2);
    }
    }
    delay(50);
    if(rc_pulse1<1023) {
    mpwm1,mpwm2=map(rc_pulse1,1023,0,0,255);
    if(mpwm1,mpwm2>0) {
    analogWrite(4,mpwm1);
    analogWrite(6,mpwm2);
    }
    }
    delay(50);

    if(rc_pulse2>1024) {
    mpwm3,mpwm4=map(rc_pulse2,1024,2047,0,255);
    if(mpwm3,mpwm4>0) {
    analogWrite(7,mpwm3);
    analogWrite(9,mpwm4);
    }
    }
    delay(50);
    if(rc_pulse2<1023) {
    mpwm3,mpwm4=map(rc_pulse2,1023,0,0,255);
    if(mpwm3,mpwm4>0) {
    analogWrite(8,mpwm3);
    analogWrite(10,mpwm4);
    }
    }
    delay(50);
    }

    Pretty good but I think you kinda copied the dronebot workshop
