L289 MOTOR DRIVER DOWNLOAD
This is in my opinion the smart way to go to save time, money, and effort. This will result in the motors stopping slowly and naturally from friction. Usage Follow the steps below to configure the motor controller board to work as a typical robot motor driver for use with two DC motors. It is powerful enough to drive motors from V at up to 2A peak. If using this material on another site, please provide a link back to my site. Perhaps an updated version will include these internally.

LN Motor Controller Theory Projects
This included power connectors, diodes, LED indicators, and even a 5-volt regulator. Welcome visitor you can login or create an account. The current sense pins jotor general can be tied to ground, but one can insert low value resistor, whose voltage reading is proportional to current. Note that “forward” and mohor refer to the direction of the motors themselves. Basic circuit configuration LN.
Internally the LN consists of four independent power amps with 5-volt digital inputs and four high current, high voltage power amplifiers capable of driving single DC motors, and both unipolar and bi-polar stepper motors.
The same method is used to control Motor B: I have used more common 1N rectifier diodes and they seem to work fine. It is powerful enough to drive motors from V at up to 2A peak.
How to use the LN Dual H-Bridge Motor Driver
It features a powerful LN motor mootr module with a heavy duty heat sink. This is in my opinion the smart way to go to save time, money, and effort.
In this series we will explore how to use the LN in a number of actual tested and functioning circuits. Otherwise you must input 5V regulated power at pin 5 so that the circuit can operate properly. Here are some handy tables to show the various modes of operation.
Usage Follow the steps below to configure the motor controller board to work as a typical robot motor driver for use with two DC motors. This will result in the motors stopping slowly and naturally from friction. D1 – D8 are used for this purpose. Motor Driver Truth Tables Here are some handy tables to show the various modes of operation.
Do not enable the onboard 5V regulator if you are supplying more than 16V to motors on pin 3 or the regulator will burn out. They can be 1N Schottky diodes.
The longer the PWM duty cycle is, the faster the motor will turn. This part seems to be the favorite of hobby robot builders. The two enable pins should be tied together. An onboard 5V regulator is provided that can be used to power other parts of your robot’s circuitry such as an Arduino microcontroller.
When these pins are Motkr, power is output to the motor. The four amplifiers are usually used in pairs forming an H-bridge to switch polarity for to control the direction of a single DC motor or as two pairs of H-bridges a bi-polar stepper motor. As shown in the above illustrations I have redrawn the “multi-watt” package into a more understandable form.
Arduino Motor Shield (L298N) (SKU:DRI0009)
Perhaps an updated version will include these internally. If using this material on another site, please provide a link back to my site. This completes our introduction to the LN dual full bridge driver.
Web site Copyright Lewis LoflinAll rights reserved. One of the annoying features of the unit is the lack of internal parasitic flywheel diodes to deal with voltage spikes. Do not enable the onboard 5V regulator if you plan to supply more than 16V to your motors. Leave the jumper connected when not using current sense.
How to use the L298N Dual H-Bridge Motor Driver
Motr use the current sense feature, remove the jumpers and attach to the header pins. In the proceeding sections we will connect the LN to a micro-controller to operate a bi-polar stepper motor and explore using pulse-width-modulation PWM to control motor speed on a standard DC motor.
