I have a doubt inorder to power a 6v DC motor do i need to provide power >6v or 6v along can power up the motor, is there any voltage drop in this driver ?

[@robojax]

Yes there is voltage drpop of about 0.7V. This is not introduction video. I have explained it in the introduction to L298N.

Hi, I'm very new in arduino uno coding. I was looking for your lesson 55 code that control motor with l298n. The code is very nice but it's a little bit to much for what i'm looking for. I Just need to control the motor cw start by 1 switch and stop with another switch and than, after stop, turn a LED on with a digital IO. Can you help me? I can read and understand some easy codes but my knoledge is too Light to write the code myself. Thanks

Hi, I got your email and responded.

Thanks, awesome video! Please, do you have some video or coding to apply these steps for ESP 32? Thanks again @Robojax

There is esp8266 video you can learn from

motor one is working but the second motor is not, knowing that i changed the code and declared all the pins: #include // motor 1 settings #define IN1 2 #define IN2 4 #define ENA 3 // ~this pin must be PWM enabled pin // motor 2 settings #define IN3 7 #define IN4 6 #define ENB 5 // ~this pin must be PWM enabled pin const int CCW = 2; // do not change const int CW = 1; // do not change #define motor1 1 // do not change #define motor2 2 // do not change const int pushButtonDelayTime =200; //*** Push buttons for motor 1 started int motor1Speed =60;// speed of motor 1 in % (60 means 60%) const int motor1PushButtonDirection = 8;// push button for direcion change const int motor1PushButtonStop = 9;// push button for START/STOP const int motor1Minimum =15;//30% is minimum for motor 1 // do not change below this line int motor1Direction =CCW;// int motor1StopState=HIGH;//Stope state of motor 1 //*** Push buttons for motor 1 started ended //%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% //*** Push buttons for motor 2 started int motor1Speed =60;// speed of motor 1 in % (60 means 60%) const int motor2PushButtonDirection = 10;// push button for direcion change const int motor2PushButtonStop = 11;// push button for START/STOP const int motor2Minimum =15;//30% is minimum for motor 1 // do not change below this line int motor2Direction =CCW;// int motor2StopState=HIGH;//Stope state of motor 1 //*** Push buttons for motor 2 started ended //%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% // use the line below for single motor //Robojax_L298N_DC_motor motor(IN1, IN2, ENA, true); // use the line below for two motors Robojax_L298N_DC_motor motor(IN1, IN2, ENA, IN3, IN4, ENB, true); void setup() { Serial.begin(115200); motor.begin(); //L298N DC Motor by Robojax.com pinMode(motor1PushButtonDirection, INPUT_PULLUP); pinMode(motor1PushButtonStop, INPUT_PULLUP); //L298N DC Motor by Robojax.com pinMode(motor2PushButtonDirection, INPUT_PULLUP); pinMode(motor2PushButtonStop, INPUT_PULLUP); } void loop() { updateState1();//read all push 1 buttons if(motor1StopState ==HIGH) { motor.brake(motor1); }else{ motor.rotate(motor1, motor1Speed, motor1Direction); } //motor.demo(1); //motor.rotate(motor1, motor1Speed, CW);//run motor1 at 60% speed in CW direction delay(pushButtonDelayTime); updateState2();//read all push 1 buttons if(motor2StopState ==HIGH) { motor.brake(motor2); }else{ motor.rotate(motor2, motor2Speed, motor2Direction); } //motor.demo(1); //motor.rotate(motor1, motor1Speed, CW);//run motor1 at 60% speed in CW direction delay(pushButtonDelayTime); }// /* * * updateState1() * @brief reads push buttons and updates values * @param none * @return no return * Written by Ahmad Shamshiri for robojax.com * on Oct 13, 2019 in Ajax, Ontario, Canada */ void updateState1() { if(digitalRead(motor1PushButtonDirection) ==LOW){ if(motor1Direction ==CW) { motor1Direction =CCW;// Serial.println("*****Now CCW"); }else{ motor1Direction =CW;// Serial.println("*****Now CC"); } } if(digitalRead(motor1PushButtonStop) ==LOW) { motor1StopState =1-motor1StopState;// toggle Star/stop } }//updateState end void updateState2() { if(digitalRead(motor2PushButtonDirection) ==LOW){ if(motor2Direction ==CW) { motor2Direction =CCW;// Serial.println("*****Now CCW"); }else{ motor2Direction =CW;// Serial.println("*****Now CC"); } } if(digitalRead(motor2PushButtonStop) ==LOW) { motor2StopState =1-motor2StopState;// toggle Star/stop } }//updateState end

why you posted the whole code. the code is part of the library and we all know how it looks like. your comment was treated by KZbin as spam and thanksfully I just checked today. Usually I check it every 2 or 3 weeks. Please use the provided code without any modification. if you do and it does not work, then the wriing is incorrect. firx the woring.
