How to control DC motor with Raspberry Pivot and L298 motor drive

What is the L298? L298 is called bidirectional motor driver, which is based on a dual H-bridge motor driver IC. This circuit allows you to individually control two DC motors in either direction. It is a common component prototypes and projects fans, because it is easy to use, and may be connected to the L298 Raspberry Pi or Arduino. In addition to the minimum design, it also provides 5V regulator board, can easily 5V to power the circuit. There are many on the market based on the L298 motor driver module, you can use any locally available based on the motor drive L298, as they are basically the same. I used the L298 breakout board, which makes it easier to set up. You can find several different L298 breakout board online. The L298 is connected to the Raspberry Pi Raspberry Pi control using a DC motor can be easily achieved. We use L298 motor driver to control the DC motor, which allows the motor to move forward or backward. For communication, we will use a simple USB cable via serial communication. So, let's get started. The IN1 is connected to the L298 pin 26 Raspberry Pi. IN2 L298 is connected to pin number 20 Raspberry Pi. ENA and connecting pins 12 volt to 9 volt battery. Make sure the battery ground, Raspberry Pi and L298 are common. Run the program and code Open Raspberry Pi Python 3 and open in a new window .. Write the following code in the new window and save it on your desktop. Import sys import time import RPi.GPIO as GPIO mode = GPIO.getmode () GPIO.cleanup () Forward = 26 Backward = 20 sleeptime = 1 GPIO.setmode (GPIO.BOARD) GPIO.setup (Forward, GPIO.OUT) GPIO.setup (Backward, GPIO.OUT) def forward (x): GPIO.output (Forward, GPIO.HIGH) print ( "Moving Forward") time.sleep (x) GPIO.output (Forward, GPIO.LOW) def reverse (x): GPIO.output (Backward, GPIO.HIGH) print ( "Moving Backward") time.sleep (x) GPIO.output (Backward, GPIO.LOW) while (1): forward (5) reverse (5) GPIO.cleanup () Make sure the Raspberry Pi L298N connected, as shown in the circuit diagram above. Then, run the code you just wrote. Code Description L298 library required in the above example, the code G from the introduction system comprises a start time and PIO. Notably, GPIO to provide high and low logic L298, time libraries for adding a delay between the different actions. Forward and reverse function parameter declarations in this code with the option. Parameter is a delay time maintaining the motor in a desired direction. It is the way you should be able to control the motor with the Raspberry Pi and L298 motor driver. You can find more code online variants to add additional functionality to the motor! Read more
