Arduino mega adk - dc motor stop by switch.

e14 Contributor

Hi guys, I am quite new with arduino, I am workin on old arcade photobooth, and I stuck, I need some help,

 

we redesign compleatly software, and I use arduino for mechanical parts, we use serial port comunication to mange hardware.

 

this is small part of the project

 

let me explain what I am working on now: I have a 2 motors 12v (I have own power source 12v), they are design to move little part forward and then part goes back to start possition (it is kind of ejecting mechanism for keyring), when back to start possition it hit microswitch, when hit microswitch it should switch off the motor. Until it will receive another "start" command from serial port

ive been going with some examples for weeks, but most of the people use motor sheilds, can this actually be done by arduino it self without the motor shield ?
i am very confused right now and I dont know how to even start, can someone please help me with the code ?

 

many thanks guys

 

 

 

p.s.

this project is devided by 3 parts, I did first 2 but stuck on 3 which is motors image

 

1. joystick + 2 buttons comunicate with android box over usb serial port
2. coin mechanism send to serial ports amount of money was inserted to coin mech
3. eject mechanism for keyring which I am stuck on right now :|

    can this actually be done by arduino it self without the motor shield?

    Sure.

    In the same manner as you can manually control a motor with a relay, or transistors/mosfets.

    Because you are controlling 12v motors (regardless of their current) you'll need something inbetween the Arduino and the motors.

     

    The motor shield simply provides pieces of hardware on a pcb, that connects to the pins required.

    There are standalone motor driver boards that connect to the required pins from most of the suppliers.

     

    You can either use the microswitch to directly control part of the motor drive, or simply detect it with the Arduino code and stop sending the motor control signal.

     

    Whatever method you use, you should be able to simulate it using leds until you sort out your code.

     

     

    Sorry I have enough of my own projects to write your code...however we can always point out things in your code if you want to post it (or parts that seem to not function)
