USING THE L298N MOTOR DRIVER SOFTWARE
To competeing this task we have work on programming which is done in Arduino IDE after completion of that we design our simulation in the Proteus software after finishing that we compile our coding in Arduino hardware. It main purpose of using L298N is that it can control speed and direction of DC motor. i2c_bus, i2c_addr = 0x29 ) ( 'distance' ) def _observe_distance ( self, change ): new_distance_value = change def set_motors ( self, left_speed, right_speed ): self.

Instance ( Vl53l1x ) distance = traitlets. Instance ( Motor ) tof_sensor = traitlets. Instance ( Motor ) right_motor = traitlets. vl53l1x import Vl53l1x import RPi.GPIO as GPIO class Robot ( SingletonConfigurable ): left_motor = traitlets. The jumper should not be placed when the power supply is greater than 12V and separate 5V should be given through 5V terminal to power the internal circuitry.ĮNA & ENB pins are speed control pins for Motor A and Motor B while IN1& IN2 and IN3 & IN4 are direction control pins for Motor A and Motor B.Import time import traitlets from import SingletonConfigurable from. When the power supply is less than or equal to 12V, then the internal circuitry will be powered by the voltage regulator and the 5V pin can be used as an output pin to power the microcontroller. The L298N Motor Driver module consists of an L298 Motor Driver IC, 78M05 Voltage Regulator, resistors, capacitor, Power LED, 5V jumper in an integrated circuit.ħ8M05 Voltage regulator will be enabled only when the jumper is placed. Related Components: LM298 Motor Driver IC, 78M05 Voltage Regulator, Capacitors, Resistors, Heat Sink Supplies power for the switching logic circuitry inside L298N ICĪlternate Driver Modules: TMC2209, DRV8825, A4988, L9110S, DRV8711 Used to control the spinning direction of Motor B Used to control the spinning direction of Motor A L298N Module can control up to 4 DC motors, or 2 DC motors with directional and speed control. This module consists of an L298 motor driver IC and a 78M05 5V regulator.
