Arduino Based Skittles Colour Sorter - Make Your Own

In this video, I’ll be showing you how to build your own Skittles or M&M colour sorter using an Arduino, a colour sensor and a few other small components. This sorter allows you to pour in a batch of Skittles and then sorts them into their five colours automatically.
To download the code and print files, a detailed write-up on the build can be accessed through this link - www.the-diy-life.com/arduino-...

Great video thank you for sharing

[@kacamataruru4473]

if i used tcs3200 help me sir find the exact code for arduino uno

[@menasheaharonian9183]

Thank you very much. Nice way to identify the color... How do I convert the sensor values to rgb values to light up a led with the suitable skittle color? Can you pls give a good conversion formula?

[@MichaelKlements]

You could combined portions of code from this project and my colour picker project. The colour picker does just that - www.the-diy-life.com/arduino-rgb-colour-picker-pick-colours-from-real-life-objects/

Hello, Love everything but your funnel stl in the zip file is missing? Can you provide that??

[@jebdulles5809]

We need, or at least I need a popcorn color sorter (Yes, each color has a unique texture and taste) Purple is my preference.

[@MichaelKlements]

That sounds cool! It would be quite difficult to build a hopper or picker to just take one piece of popcorn due to its irregular shape and size.

[@bread-mp5kx]

Nice

[@CalebSkurdal]

This is excellent! I have everything printed except the hopper. Do you have the STL for it?

[@travisgould7851]

i had to design my own .

[@HeavensLastHope]

What wasn't mentioned was how long it took for it to sort 1 Skittle. I know this is a year old video, but was curious. I like this idea and thought it could be used for sorting buckets of perler / hama / artkal melting beads. So wondering how efficient it is and if you've made it any more efficient with further testing. Thanks!

[@MichaelKlements]

It takes around 3-4 seconds per skittle, depending on how far the chute has to move. I didn't really play around with trying to make it faster, although there are definitely some things which could be done to improve it. The servo which moves the skittle from the hopper to the sensor and then chute is running really slowly. If you got good quality 3D printed parts then you could tighten up the tolerances and speed this up significantly as the sensor doesn't even need a second to read the colour. You could also use a higher speed servo on the chute to reduce the waiting time.

Where do i get the pole from??

DE DONDE SACAS ESTOS VALORES? int colourRedSP = 85; int colourGreenSPGP = 97; int colourGreenSPY = 91; int colourGreenSPO = 81;

[@MichaelKlements]

From putting a known colour skittle through the sensor and seeing what value it measures

[@EndexPlay]

Download links are not working. Can you update them?

[@MichaelKlements]

Thanks Endex Play, I've amended the description and checked the link. You can download the part files and code through the write-up page.

[@EndexPlay]

@@MichaelKlements Thanks a lot!

[@Marctew]

I love the idea.....however, hot glueing the tubes in place is a poor design, how will you empty them without tipping the whole thing upside down?

[@MichaelKlements]

Yeah I agree this wasn't a good idea. Using hook and loop straps or some ties would have been better.

[@JohnRHales]

I would have watched the whole video if it didn't have that infuriating music

[@alvid98]

Too slow

[@minopausa]

Thumb down for the music. Hope that helps.

[@reedsmith6422]

Down voted due to music. Why's it needed?

[@MikeMcRoberts]

Agree. We want to hear the machine in use, not some terrible music. There just seems to be this thing that you just HAVE to add music to tech videos and I wish it was a thing that would just die. It's so cringy.
