I mean, you could solder the pins UP and connect the Stepper Motor and Arduino pins that way, but those connections would not be very secured.The maximum current it can supply is 750mA per coil. In this tutorial i'm going to show you how to control the speed and direction of two DC motors by the most common method PWM signals. This code is make a motor rotate One step at a time using L298N Motor driver . Watch video for the complete explanationIf you found this tutorial helpful, please support me so I can continue creating content like this. In these examples I will be using the AccelStepper library. The L298 Dubai H Bridge is base on l298 Chip manufacture by ST Semiconductor.
The L298N module has a very famous L298 Motor driver IC which is the main part of this module. In this example, a potentiometer (or other sensor) on analog input 0 is used to control the rotational speed of a stepper motor using the Arduino Stepper Library.
The motor is attached to digital pins 8 - 11 of the Arduino. Specifications of L298N Motor Driver The Stepper Motors therefore are manufactured with steps per revolution of 12, 24, 72, 144, 180, and 200, resulting in stepping angles of 30, 15, 5, 2.5, 2, and 1.8 degrees per step. Since most of the time we’re using Stepper Motors with 2 coils, then this maximum go up to 1.5Amps.The EasyDriver is pretty power efficient, but it’s still a good idea to install a heatsink if you’re gonna come close to hitting the current limit.There is a version of the EasyDriver that can provide up to 2A per coil… the ‘BIG EasyDriver’, and I’ll have a look at that one in a future tutorial.So if your stepper motor requires more , then you can’t really use the EasyDriver… Well… you can, but the Stepper Motor will not have the same amount of torque.You can operate the EasyDriver with as little as 2 Digital pins from an Arduino, which is great if your project is running out of them.Of course you’ll need more if you want to control the type of steps, and enable/disable, but it’s still an option.The EasyDriver does have a small potentiometer onboard that enables you to limit the amount of current fed to the stepper motor… So if you have very small motors that have a maximum rating of let’s say 500mA you can adjust this pot accordingly and not have your stepper overheat as much.Also it’s able to adjust the current while running the stepper or when the stepper is stopped, this reduces the amount of heat generated.Another big benefit is that you can adjust the type of steps you want to achieve.Most stepper motors are 200 steps per revolution using Full Steps.The EasyDriver can do Full Steps, but also: half step , 1/4 step, and 1/8 step.For example if you want more precision or smoother motion, you can set it up to do 1/8 steps, which will give you 1600 steps per revolution.And this can be adjusted inside the Arduino code directly, no jumpers needed.To power the EasyDriver you can use any power supply (depending on your stepper motor specs), from 6V to 30V, it has a 5V regulator onboard that power the onboard electronics and can provides clean 5V (up to 500mA) that you can use to power your Arduino.In closing the EasyDriver is a better driver in many ways, but is of course a little more expensive.For simple projects or just to test Stepper Motors, the L298N might be a good choice.At first glance, when looking at the L298N driver, you see it comes pre-installed with a pretty big heatsink.You might be thinking “well, that’s better than the EasyDriver”Well yes and no, you see the L298N is not very efficient when it comes to power, and that’s why it needs that heatsink…The EasyDriver is better so it can get away without one, within limits of course.Keep in mind that the L298N doesn’t have all the bells and whistles that more advanced driver have.For example it only supports Full Steps on it’s own, but will support Half Steps when using the AccelStepper Arduino Library.The L298N is easy to find, very cheap, but the big plus for me is that it’s much easier to connect.You see the L298N comes with Screw Terminals already soldered on for connection the Stepper Motor wires and power supply lines very easily.Also the pins to connect to an Arduino are already there and ready to go.The L298N can take from 5V to 35V… It also has a 5V regulator onboard, but unlike the EasyDriver, this one will only work up to 12V input, if you supply over 12V to the L298N you need to disable the onboard regulator with a jumper, and provide your own 5V supply for the onboard electronics and the Arduino.Now on paper the L298N can provide up to 2A of power per coil, but in reality it will go into thermal shutdown before getting even close to that because of the bad efficiency.
