Description

ABSTRACT

Dual H-Bridge, which is used to change the polarity of the supply which is given to the DC/Stepper motor. Normally we are using L293D Driver IC to run the motor. Based on the model of motor used current and voltage vary. Dual H-Bridge L298, which handles more current and voltage when compared to L293d. Here you will learn to use Dual-H bridge to control DC motor using Raspberry Pi with Python programming.

BLOCK DIAGRAM

BLOCK DIAGRAM DESCRIPTION

In the above block diagram, Dual H-Bridge (L298) is connected to the GPIO pins of Raspberry Pi, then the DC motor is connected to the Driver.

 

PROJECT DESCRIPTION

In this Raspberry Pi projects, you can use multiple PWM using this H Bridge, and also L298 can handle more current and voltage when compared to the L293, so we are using H-Bridge and also used to change the polarity of the motor which is connected to the Bridge, to make them rotate clockwise and anti-clockwise direction.

 

HARDWARE REQUIRED

• Raspberry Pi
• Power Adapter
• HDMI to VGA converter (optional, when connecting to Monitor)
• L298 (Dual H-Bridge)
• DC Motor

SOFTWARE REQUIRED

• Raspbian Jessie
• SD Card Formatter
• Win32 Disk Imager (or) Etcher

 

LIBRARIES USED

• Rpi.GPIO as GPIO (To access GPIO Pins of Raspberry Pi)
• Time library (For Delay functions)

 

CONCLUSION

This project helps you to work with any type of DC  and Stepper motor, which can handle any current and voltage when compared to L2932D.
