The H-Bridge that you will use in this tutorial is great if you are using an Arduino Uno or other microcontroller that operates at 5Volts. There is a minimum PWM value that will make the motor move. Therefore, the motor can be utilized with its full bidirectional capability. When we move the 10k pot in one direction, the DC motor rotates in one direction and when we move the Pot to opposite direction then the motor also rotate in opposite direction. Below animation illustrates H-Bridge circuit working. In this tutorial, we will show you how to make an H bridge circuit using two 555 timer ICs. or a temperature sensor? Hi, I am building an H Bridge to drive a 2A @ 12V motor and I am using a 555 timer for the signal, so I tested the circuit at 7.5V DC but the motor only rotates in one direction, I use a 4.7k variable resistor for controlling the motor and this only makes the motor speed slow when the variable is turned fully anti-clockwise n the speed fast wen the variable is turned fully clockwise. To control the direction of the spin of DC motor, without interchanging the leads, you can use a circuit called an H-Bridge.An H-bridge is an electronic circuit that can drive the motor in both directions. The ground is all the way off, terminal 2 is the switch itself, and terminal 3 is the switch turned all the way up. Figure 10 MOSFET H-Bridge motor control with motor power on-off control. DC Motor W/ H Bridge, Potentiometer, 2 Buttons. DC motor is the most used motor in Robotics and electronics projects.For controlling the speed of DC motor we have various methods, like the speed can be automatically controlled based on temperature but in this project PWM method will be used to control the speed of DC motor. By moving the knob of the potentiometer, we will be varying the resistance between Pin 2 and Pin 6 of the IC. Fig. DC Motor W/ H Bridge, Potentiometer, 2 Buttons. Two constant resistors (R 1 and R 3) a potentiometer and the unknown resistor are forming the two legs of a circuit which are bridged by a voltmeter or an ammeter. H bridge circuit mostly contains 4 transistors that drive the motor in both directions. Jacob Edward Jacob Edward. When we move the Pot in opposite direction, the voltage at Threshold PIN 6 goes above the 2/3Vcc, which is the non-inverting input of Upper comparator inside the 555 IC.
