Topic: Coin segregation using motors - need help (Read 2 times) previous topic - next topic


hey Guys... Need your advise on this.
from coin slot to coin segregation, so what do you think?

- I plan on using ARDUINO UNO
- Mainly i have thought of 2 Designs on how to do the separation of coins when it comes out of the coin slot. I have included images so you can see the my ideas.

- for the 1st one (three shutters in alignment with the path of the coin), when a specific coin is detected the corresponding shutter will open.
- for the 2nd one (using One Motor), when a specific coin is detected it rotates to a specific and programmed angle.

- p.s. it would be most efficient if anyone can suggest how can i make the shutters in the first design reverse rotate to set it back into position.
- What do you think is more Economical, Efficient, and above all much easier to do of the two?

- Need your suggestions/advise/comments/recommendations on this. What do you recommend on the 2 designs?
- if so, what motors can i use?


- if so, what motors can i use?

For either method I would think standard R/C hobby servo(s) would be the simplest and least expensive form of motor control for opening and closing 'trap doors' or rotating a mechanical steering path. R/C servos are easy to use in arduino sketches and don't require any addition hardware like motor driver shields and such. Servos do however require a separate 5vdc power source to operate well as powering servos from a arduino's 5V shield pin is problematic from a current capacity point of view.



A second vote for servos. I prefer design one - it seems like the second might need substantial power to move the whole assembly to point to the appropriate track for each coin and there's potential to miss if the thing is still moving. With design one, the worst that will happen is that the coin ends up in the 'not recognised' bin at the end of the track.


Im with the two guys above me, servo. design one seem like a more feasible way to do it


Are you planning to make this like a coin sorter? It also be cool if you put in a Display to count the coins 8)
One Component at a time.
