How do Video Game Controllers Work? || Exploring a PS4 Game Controller

Almost all the console video games you play use this small metal disk. But where is it located and what does it do? In this video, we will open a PlayStation 4 Dualshock video game controller and see how the buttons and analog sticks work! This controller is similar to a PlayStation 5 [PS5], a Nintendo Switch Joy Con, or an Xbox X Series video game controller.

    Joystick drift.

  2. Irshad Desai on March 17, 2022 at 5:38 pm

    Thank you so much

  3. Joa Marticorena on March 17, 2022 at 5:39 pm

    nice video, just one consideration: it would be better if you explained how the antena and electromagnetic signals of the controller works

  4. Mehdi K on March 17, 2022 at 5:39 pm

    Realy real great…

  5. Trent Boman on March 17, 2022 at 5:40 pm

    Analog stick contact. 1:06

  6. SparrowTheNerd on March 17, 2022 at 5:40 pm

    figured it out when you said there were 4 at 3:02

  7. Justinio on March 17, 2022 at 5:40 pm

    5:46 Was making a sandwich while listening to this, and I thought this copyright-free music coming on was a funny animals tik tok ad I’d need to skip or something, LOL! Very, very educational videos on this channel though, coming from the mouse episode. I am definitely staying subscribed! 😀

    When I graduate college ~20yrs ago, making these kinds of 3d models was an entire career. Visualizing component layout was quintessential for designing the housing, peripherals, etc. Now, a full 3d model can be made in a free tool from the internet, along with hundreds of tutorials on how to build such things. And the end result can be sold online, license-free, for only 25 bucks. It’s a humbling reminder of how fast technology changes, and how channels like this are paramount for us aging nerds that are just trying to keep up =]

    I figured out the moment you showed this disk, this little sucker is very annoying once it deforms, your game camera will go bonkers without it 😂😂

  10. Falin on March 17, 2022 at 5:44 pm

    1:00 is the wiper of a potenciometer on the joysticks or maybe in the triggers
    EDIT: just realised that triggers uses presure sensitive buttons

  11. Brandi Sheppard on March 17, 2022 at 5:48 pm

    21 seconds the disc goes in the analog. It is what makes the joystick drift when it goes bad

  12. Meme Cafe on March 17, 2022 at 5:48 pm

    controller lore

  13. Ricky Mohar on March 17, 2022 at 5:48 pm

    This was insanely educational. Loved the description of how the circuit board uses resistance calculation for the analog sticks ‘ acceleration

  14. Lemuel Wonah on March 17, 2022 at 5:49 pm

    0:25 I’ve taken my pad apart wayyy to many times to try to ‘troubleshoot’ my analog issues

  15. Ansjelo on March 17, 2022 at 5:50 pm

    Sadly i know how it works after broken and repaired so many controllers bcs of fifa

  16. Andrew Boyle on March 17, 2022 at 5:51 pm


  17. Suman Halder on March 17, 2022 at 5:53 pm

    Just brilliant keep it up

  18. Fun Guy on March 17, 2022 at 5:53 pm

    Visual education for the win!!

  19. Kage1128 on March 17, 2022 at 5:58 pm

    1:56 the object is located under the analog sticks?

  20. Ehrenkind on March 17, 2022 at 5:59 pm

    I already know since I disassembled it, I wont write a timestamp / participate so I wont influence any results.

  21. MrRedstone on March 17, 2022 at 6:00 pm

    I figured from the start that the metal disc is the wiper contact for the analog joysticks. Did you know that the reason why Switch joysticks drift is that the backplate which holds the joysticks together buckles, breaking the contact between the wiper disc and the track? The fixes only work temporarily because the backplate will eventually buckle again. A permanent fix is to put something in between the joystick housing and the joycon shell. It presses the joystick housing back together.

  22. Dileep Dilraj on March 17, 2022 at 6:01 pm

    you are really amazing even I cant get this subject in college also

  23. 날먹 on March 17, 2022 at 6:09 pm

    I love kind of these videos! There are so many coolest thing in the world!! And I really hope to know how VR controllor works!

  24. prashant pisal on March 17, 2022 at 6:09 pm

    Sir your Graphics and representation is very nice 👍🙏

  25. Aisawa Loki on March 17, 2022 at 6:09 pm

    3:04 It is located inside the potentiometer of the joysticks, one per each axis across the two joysticks, thus total four. I suddenly remembered I saw something similar while I was disassembling old game controllers.

  26. Mike196 on March 17, 2022 at 6:09 pm

    I don’t know how but somehow I actually guessed what that ring was. I said it looks like it has something to do with rotation, but it probably measures resistance. Something about the rings made me think that and I was BLOWN AWAY at how the entire assembly came together!

  27. AggrievedCookie on March 17, 2022 at 6:09 pm

    As soon as the mystery component was shown I guessed joysticks

  28. D SCIENCE RESEARCH on March 17, 2022 at 6:09 pm

    1:22 i think its a roller part mechanism in joystick🕹

    It is known as wiper 😎

  29. Zavirez Clips on March 17, 2022 at 6:10 pm

    2 on each analog (5:03)

  30. Nikil Ragav on March 17, 2022 at 6:10 pm

    Flexible contact board → Flex PCB is what we called our flexible PCBs on the Google Pixel. But we’d usually say something like "USB flex PCB" for the board that has the USB connector

  31. SomeOrdinaryPigeon on March 17, 2022 at 6:10 pm

    Rubber gaskets

  32. Qopiq q on March 17, 2022 at 6:11 pm

    Wow these visuals are incredible. I wish i had this when i started IT back in the day!

  33. Nicholas White on March 17, 2022 at 6:13 pm

    Wow, amazing video

  34. Eskeret on March 17, 2022 at 6:14 pm

    hope you’re having a good day!😄

  35. javier depaz on March 17, 2022 at 6:15 pm

    Such a beautiful educational Video straight forward

  36. Lokesh Yadav on March 17, 2022 at 6:17 pm

    I found the mysterious part at 5:56 🙃

  37. firedrake rudy on March 17, 2022 at 6:19 pm

    I had guessed immediately that those metal components were involved in detecting the x and y axes on the control sticks and the fact that there are 4 in the controller confirmed it for me!

  38. BIDISH DAS on March 17, 2022 at 6:23 pm

    I broke open the analog controller out of an aeroplane remote control but never quite understood it. Thank you very much, without you I could have never understood this amazing thing.

  39. Jacques Vella Borg on March 17, 2022 at 6:24 pm

    Does the microcontroller measure the voltage or current in the potentiometer?

  40. Jon L on March 17, 2022 at 6:24 pm

    glad i found this… the ABSOLUTE POOR QUALITY of genuine PS controllers has rendered my PS4 to the shelf…. Absolutely shambolic… I was spending as much money on replacement controllers as I was on new games…. Absolute shame on you Platstation,,, you used to be my favorite since the PS1,, now I never will buy anything Playstation. REALLY POOR,,, CONSUMERS TAKE NOTE!

  41. Algosyntax on March 17, 2022 at 6:25 pm

    Now i can DIY fix my controller

  42. Josh Ryza on March 17, 2022 at 6:26 pm

    0:00 i already knew where it was

  43. Nightweaver20xx on March 17, 2022 at 6:27 pm

    So what causes analog stick drift? And buttons to start sticking?

  44. Ibrahim Bek on March 17, 2022 at 6:29 pm

    Thank you

  45. Mike196 on March 17, 2022 at 6:29 pm

    Another fantastic video. You never cease to amaze me 🙌

  46. Gaming Domination on March 17, 2022 at 6:29 pm

    who all have already broken apart a ps2 remote for experimental purposes 🤣

  47. アリジトルガ on March 17, 2022 at 6:30 pm

    great video. square, triangle, circle, x buttons are pressure sensitive too. How is it working?

  48. Jake the Octoling on March 17, 2022 at 6:31 pm

    So the metal plate may be broken and that’s what’s causing joy con drift.

  49. FatHy Hassan on March 17, 2022 at 6:32 pm


  50. Daniel Sánchez on March 17, 2022 at 6:33 pm

    analog stcks should be designed to be replaced easily, they’re cheap but if you do not have the tools it’s imposibble to change them and you must pay someone to do that.
