The four power amplifiers and grouped in pairs of two with individual enable pins (ENA, ENB) and individual current sense pins (CSA, CSB) for each pair. The L298 uses two different supply voltages. http://arduinobymyself.blogspot.com.br/2012/08/ponte-h-controle-de-motores-dc.html This website is in Portuguese. Most of these are in kit form, so soldering is required, but they’re much easier (and often cheaper) to use than collecting and assembling all the parts yourself. Source
Also use the heat sinks when doing practically.Video lecture on L298N dc motor driverCircuit diagram of L298N motor driverHere we have simulated the above example. Each time we hit in the controls (forward or backward) the DC motor run for 1s, in this way, if we hit twice the motors will run for 2s and so Two of them form H-bridge A while other two form H-bridge B. L298 is a dual full bridge driver that has a wide operating voltage range and can handle load currents up to 3A.
D1 - D8 are used for this purpose. While wired together here, the two enable pins can be separated to turn each individual motor on/off separately. Is there any chance someone could give some more details on that side? L298 Motor Driver Datasheet i also changed my l298n to make sure the chip is fine.

This module will allow you to easily and independently control two motors of up to 2A each in both directions.It is ideal for robotic applications and well suited for connection to L298 Motor Driver Working This IC is used to control these motors. and also in bluetooth controlled robot using pic microcontroller. you can check line follower robot for more about its applications. The state of the motor will depend on the logic level of the pins 10, 11, 12 and it is described in the table shown below the circuit diagram.
Pair of H Bridge is used to control a bi-polar stepper motor.Amp A1 and A2 => H Bridge AAmp B1 and B2 => H Bridge BBasically L298N is used to drive http://www.circuitstoday.com/h-bridge-motor-control-circuit-using-l298 Collection Intro123456Introduction: Dual H-Bridge - L298 Breakout Board - HomemadeShow All ItemsThis is my homemade Dual H-Bridge using the IC L298N. L298 Motor Driver Module I have used more common 1N4001 rectifier diodes and they seem to work fine. L298 Pin Diagram The current sense pins in general can be tied to ground, but one can insert low value resistor, whose voltage reading is proportional to current.
It can source/sink up to four amps at about 40 volts with proper heat sinking. this content For control DC motors or step Motors ao other purposes just like you need. For example try to combine parts of code to move both motors simultaneously.Try to use analogWrite(pin, PWM value) instead digitalWrite(pin, HIGH/LOW) to control the speed of motors!Step 4: Well Done!You have Javi Roces (author)Reply2013-07-27hello! L298 Motor Driver Pin Diagram
Problem solved. So maybe instead of the BD 139 driver I gone to use a IGBT type: CH50DY-24H from Mitsubishi corp. & if needed bootstrap it with the Bd 139. We can use push buttons and whenever specific push button is pressed, specific motor will start running. weblink ENA will turn on A1 and A2 when with a digital HIGH (5-volts) and off when LOW (0 volts); the corresponding outputs will be floating when off.
We will use H bridge motor diver IC L298N and two DCmotors. L298 Arduino The datasheet for the L298 specifies “fast recovery” 1-amp diodes; an inexpensive selection is the 1N4933, available from most online electronic parts outlets.

H Bridge Motor Driver Circuit 2. Motor drives are of many kind depending upon the maximum supply voltage, maximum output current, rated power dissipation, load voltage and number outputs etc. We use externally these flywheel diodes.

ENA, ENB, and In1-In4 are all standard 5-volt TTL logic making connection to most micro-controllers easy. Two inputs will monitor each motor. I also have a PCB version and I can share it with you. check over here Send me your project details at my email address: [email protected] Comments nahom December 28, 2016 thanks alot what you giving the circuit and for your explanations so,furtherly if you have a
The worst-case drop in voltage is 3.2V at 1A of motor phase current and 4.9V at 2A of motor phase current. The motor driver was connected to a variable DC voltage source and twopower resistors. ENA and ENB can be connected directly together to enable both channels at once or simply tied to +5 volts and both channels making all four outputs active at all times. The cart was controlled by bluetooth (using the "Blue Control" application of the Android market).
