Why use an H-Bridge for a DC motor?

The use of H-Bridges in DC Motor control is simple and an easy way to control the direction and speed of a DC motor. The real challenge lies in choosing those Integrated circuits and power supply that are rated to handle the voltage and current the motor would draw.

How do you control a 12v DC motor with Arduino?

Arduino Motor Control Setup

Connect 5V and ground of the IC to 5V and ground of Arduino.
Connect the motor to pins 2 and 3 of the IC.
Connect IN1 of the IC to pin 8 of Arduino.
Connect IN2 of the IC to pin 9 of Arduino.
Connect EN1 of IC to pin 2 of Arduino.
Connect SENS A pin of IC to the ground.

Can an H-Bridge control motor speed?

An “H-Bridge” is an arrangement of transistors that allow you to control both the direction and speed of the motor.

Is H-Bridge a PWM?

H-Bridges. PWM is often used in conjunction with an H-Bridge. This configuration is so named because it resembles the letter H, and allows the effective voltage across the load to be doubled since the power supply can be switched across both sides of the load.

What is an H-Bridge Why do we need one instead of just using the Arduino alone?

The main reason is that the Arduino can only handle supplying a small amount of power and most motors would draw more power than the Arduino can supply. When you use the H-Bridge, you supply the power for the motor(s) from an external power source so you do not put any strain on the Arduino’s power supply.

How many DC motors can an Arduino control?

Controlling 16 DC Motors with an Arduino Uno.

Why do you need PWM and the H-Bridge?

PWM is often used in conjunction with an H-Bridge. This configuration is so named because it resembles the letter H, and allows the effective voltage across the load to be doubled since the power supply can be switched across both sides of the load.

How does an H-bridge motor driver work?

In an H-bridge, there are multiple ways to control the flow of current through a brushed DC motor. A brushed DC motor can spin in a reverse or in a forward direction. Once the current is flowing in forward or reverse direction, the direction of the current is maintained by the inductance of the motor.

How does an H-bridge work?

An H-bridge is built of four switches that control the flow of current to a load. In the image above, the load is the M connecting the two sets of switches. Using one current source, you can drive current in two directions by closing two switches.
