Technically, we have discussed all the connections you need to get a motor moving.

More on how to use these pins later in the code. The same applies for IN3 and IN4 but for the motor to the right, which we are not using in this example. These pins will control whether the left motor is stopped, moving clockwise, or moving counter clockwise. In my diagram I have an orange and blue wire connecting the IN1 and IN2 pins to pins 9 and 10 of the arduino. Look to the 4 pins in the middle as these are the INs. To the right of the power screw terminals you will find these IN pins and others. Each of these OUT connections have corresponding IN connections that you will connect to the arduino. These are where you attach the DC motors. The left and right sides of the L298N each have a pair of screw terminals. I can not confirm this personally but I believe if you are using over 12v, then you should remove the 5VEN jumper and input 5v from another source to the 5v screw terminal that you see me stealing power from. DO NOT use this regulator if you are using more than 12v, but I really can't speak to if the L298N should be used with over 12v either way. To use the 5v output, as I have done to power the arduino, you need to use a jumper connecting the two pins just north of the power screw terminals labelled 5VEN. One of the handy features I was alluding to earlier is that the L298N has a voltage regulator that we can utilize as a 5v source. This will provide the power for the DC motors. The positive and negative from this go directly to the 12V and GND screw terminals on the L298N. Starting with the far right, you will find my usual barrel jack which I use to connect a 12v 4a power supply. Second, I am only using the L298N to drive one DC motor at the moment but you can independently drive a second motor with just one driver.

I won't into the technical intricacies of the L298N, but it has some really useful features for not much money that is great for TipsyBrew.įirst off, if you haven't been keeping tabs on the project, I am using the arduino MEGA 2560 full time now because the OLED requires too much memory for the UNO to be reasonable. Here are some handy tables to show the various modes of operation.All we need here is an arduino, 12v power, 12v DC motor, and of course an L298N driver. Here are some handy tables to show the various modes of operation. To perform a quick braking operation, set ENA=LOW, IN1=LOW and IN2=LOW for Motor A and ENB=LOW, IN3=LOW and IN4=LOW for Motor B. This will result in the motors stopping slowly and naturally from friction.

To remove power from the motors, simply set ENA=LOW for Motor A and ENB=LOW for Motor B. I thought that making the two inputs receive the same signal as well as making the Enable high would essentially short the connection and put the dc motor into what I think is brake state. I think I'm sending the right info to the L298N driver but maybe I'm incorrect in my understanding on how the driver is supposed to work.

My understanding of brake state is the high torsional resistance felt on the dc motor when you connect the two leads of the dc motor together. The program works as intended to run the motor when the button is pressed but when it's released, the motor still feels as if it's not in a brake state. I'm trying to write a simple program that runs a 6v dc motor when a button is pushed and puts the motor in a brake state when the button is released.
