Then I selected cupper top in order to make the tool path for inside cut for the traces by 0.2 solid carbide end mill and the outside cut by 0.79 flat endmillĪfter I opened the selected file this is how its look like
#L298N MOTOR DRIVER EAGLE LBR SOFTWARE#
The first thing I did Is to open flat cam software then from file menue I chose open Gerber
#L298N MOTOR DRIVER EAGLE LBR ZIP FILE#
Īfter I extracted the zip file I opened flat cam, from file I chose open gerber file wich mean I opened the file that contain the traces and the board ouside cut, then I chose open Exellon file which mean I Opened the file that contain the holes that I want to drill. In order to use flat cam I have to get the cam files from eagle - Board layout - file - generate cam dateĪnd this is the Gerber and Eexellon files that I will get in a zip file. Using autodesk Eagle I designed a board with Atmega 328 and I added 4 pins for ultrasonic sensor which are the VCC, GND and pins 3 and 4 in atmega 328 pins out also I added LDR sensor connected with AD6 also I integrated my board with ULN2003AN and here is the schematic and board designs:Īfter I designed my board I used the cam processor FLAT CAM

Yea I had I big problem I forgot to add a capacitor of 100uf connected with RX so because of it I couldnt use the FTDI cable and I used the Arduino as ISP to program my board after I made another board and I have equiped ULN2003UN on it Then I uploaded it to arduino and I removed the usb from my pc. Steps: the number of steps to turn the motor.positive to turn one direction, negative to turn the other Now I will call the step function myStepper.step(stepsPerRevolution) turns the motor a specific number of steps, at a speed determined by the most recent call to setSpeed() above the void function This function doesn't make the motor turn, just sets the speed at which it will when you call step(). Stepper: setSpeed(rpms).Sets the motor speed in rotations per minute (RPMs). Steps: the number of steps in one revolution of my motor that I have calculated it. The number of parameters depends on how you've wired your motor, in my case I have 4 wires. it is used at the top of the sketch, above setup() and loop(). This function creates a new instance of the Stepper class that represents a particular stepper motor attached to my Arduino board.

Here, 360/1.8(from data sheet) = 200 steps per revolution.Īfter we have the stepper function Stepper(steps, pin1, pin2, pin3, pin4)
#L298N MOTOR DRIVER EAGLE LBR HOW TO#
It is important to know how to calculate the steps per Revolution for the stepper motor because only then you can program it effectively.
#L298N MOTOR DRIVER EAGLE LBR CODE#
The firs thing I included the stepper library in the code (include stepper.h)Īfter I defined a constant integer variable for steps per revolution. This is the connection between l298 and stepper with arduino JAMECO 2-Phase 5VDC 1A Bipolar Stepper Motor 237490įrom the data sheet I Knew the coils wires In our fablab we have variaty types of stepper motors and I used the 4 wires bipolar stepper motor from JAMECO The connection in this code the power sorce is connected with 5v port and GND in the L298N and the PWM pin connected with ATIVA MA and pin 2 and 3 with MOTOR A in L298N

Now the 3ed code i will use the analog pin which is pwm 5 in my board D4 to slow the rotation in one direction and make it faster in the other direction In the loop function, I added another direction of rotation by swiching the pins mode high to low - low to high Now I will make the rotation by both directions with a delay of 2 seconds In the loop function,the pin 2 is high and pin 3 is low that mean the motor will keep the rotation in one direction Then I wrote a simple code using arduino c to make a rotation Then from tools I chose the following and then Burn bootloader I used the arduino as isp then I uploaded the code I'm going to program a DC motor in which i will make the rotation of the motor in two directions by changing the pins for example if we changed the polarities then the direction of rotation will reflect and for thet we can use H bridge drive circuitĪnd then I will make a change in the rotation speed by using analog pin.ĭ1 and D2 are for digitat pins and D4 is analog pinĪfter my demonstration lets do programming :D
