The motor should now run first in the clockwise (CW) direction for 3 seconds and then counter-clockwise (CCW) for 3 seconds.

Provide power to the Arduino board using power supply, battery or USB cable.

#ARDUINO STEPPER MOTOR SERIAL CONTROL CABLE SOFTWARE#

Connect the Arduino using Arduino USB cable and upload the program to the Arduino using Arduino IDE software or Arduino Web Editor.

Connect SENS A pin of IC to the ground.

Connect IN2 of the IC to pin 9 of Arduino.

Connect IN1 of the IC to pin 8 of Arduino.

Connect the motor to pins 2 and 3 of the IC.

Connect 5V and ground of the IC to 5V and ground of Arduino.

For Anti Clock-wise motion - IN_1 = LOW, IN_2 = HIGHĭc_ Arduino Motor Control Setup For Clock wise motion, in_1 = High, in_2 = Low PinMode(in_1,OUTPUT) //Logic pins are also set as output PinMode(pwm,OUTPUT) //we have to set PWM pin as output For providing logic to L298 IC to choose the direction of the DC motor To set the values of Arduino pins 8 and 9, we will use the digitalWrite() function, and to set the value of pin 2, we will use the using analogWrite() function.Ĭonst int pwm = 2 //initializing pin 2 as pwm This will control the speed of the motor. The EN A pin of IC is connected to the PWM pin 2 of Arduino. These two digital pins of Arduino control the direction of the motor. IN1 pin of the L298 IC is connected to pin 8 of the Arduino while IN2 is connected to pin 9. The following table shows which direction the motor will turn based on the digital values of IN1 and IN2. ON or OFF inputs, while pin 6 needs a pulse-width modulated (PWM) signal to control the motor speed. Since we will be controlling only one motor in this tutorial, we will connect the Arduino to IN1 (pin 5), IN2 (pin 7), and Enable1 (pin 6) of the L298 IC. There are three input pins for each motor, including Input1 (IN1), Input2 (IN2), and Enable1 (EN1) for Motor1 and Input3, Input4, and Enable2 for Motor2.

The schematic above shows how to connect the L298 IC to control two motors. The pinouts for the L298 are shown below. At these currents, however, you will need to use heat sinks. The L298 can control the speed and direction of DC motors and stepper motors and can control two motors simultaneously. You can use discrete transistors to make this circuit, but for this tutorial, we will be using the L298 H-Bridge IC. It is called an H-bridge because it uses four transistors connected in such a way that the schematic diagram looks like an 'H.' H-bridges are used in many different applications, one of the most common being to control motors in robots. An H bridge is an electronic circuit that can drive the motor in both directions. To control the direction of the spin of DC motor, without changing the way that the leads are connected, you can use a circuit called an H-Bridge. If you switch the leads, the motor will rotate in the opposite direction. If you connect these two leads directly to a battery, the motor will rotate. DC motors normally have just two leads, one positive and one negative. If this question is better asked on a different thread, please direct me to it.By connecting an L298 bridge IC to an Arduino, you can control a DC motor.Ī direct current, or DC, motor is the most common type of motor.

This is just some code so I can try and learn a little something and make some strange stuff in the future.

I am new to coding, so for the love of god, go easy on me! I have added my full code so someone a little higher up in the coding world will see what I am doing. I know the problem is in the loop, but for the life of me I can't seem to figure it out. I added a bit of feedback so I could see what my direction variable is doing, it will hold a '1', make the move, rehome and show a '0'. If I enter a 0 the stepper will make one turn in the CW direction then repeat that move. If I enter a 1 the stepper will rotate one turn in the CCW direction, hit the home mark then reverse and go CW. I have the homing function working, however the loop that reads the data from the serial monitor and returns it to the program is acting really buggy. I am attempting to create a simple code that will home the motor then wait for input for direction.
