The matrix is multiplexed using two 74HC595 shift registers, one driving the eight anodes and the other the eight cathodes.
I am trying to do this currently with Ds Lite consoles and 3ds consoles. I dont know exactly how to get the resistors in without accidentally soldering other contacts, did you use a jumper wire from each ground to resistor and then use the contact on the other end of the resistor to each CC? It was hard to see but thats what it looked like to me! Your video was much more help to me then others i have seen so i greatly appreciate it!
I suggest making "a straight through" adapter instead where this is present.
Great job getting it right in the FIRST attempt. I wanted to know if it's possible to swap out a USB C 2.0 port on my smartphone for a USB 3.0 port.
the code have an error it said like this Sorry, it seems like your code has some errors. 8:10: fatal error: pitches.h: No such file or directory
Will you help me? I want to add more songs using one pushbutton. once I press the pushbutton, the music will change. HELP ME, plssss😔

Tetris de Baralho
A great explanation and solution to this 'issue'. The amount of devices I have that I have to have both cables is a pain! Time to get my soldering iron out!
Great video. Thanks.
C'est très bien
Fuck this nonsense for freaks
Not working with samsung charger 25w
Great learning video for dummies like me. Keep up the good videos!
How can I add QI to a table to charge battery? The board has c port that is burnt all traces!
Awesome man!
Nice project. Pro tip: Put code you want to run once in setup() and leave loop() empty.
Young man, you will eventually have to buy a microscope... :-)
Good work
Thanks I was looking for that
So to detect the CC1 and CC2 pins on the female side, you need a male USB C plug with the CC pin wired, which is pin A5. But of all the bare male plugs that I see for sale on Amazon etc, none have pin A5 exposed. (Most have eight pins: A2 A3 A6 A7 B11 B10 GND VBUS) How do I get a male plug with A5 exposed? I tried cutting up a C to C cable, but the board wasn't labelled and the wires didn't use standard colours so I couldn't tell which one was the CC wire. Am I missing something?
I eventually found one on an audio hardware website! After that, following the instructions was easy, and my device now charges via C to C cable. Thank you for this video!
@@PhilipBroughtonMills did you happen to have a link or know the name of the site?
@@reevesjustin RUclips is censoring my link, but you'll find one if your search for "USB Type C Male Plug Breakout Board v3.0".
daaamn those things are tiny
Is the same also possible when you need 9,12,15 or 20 volts from a power delivery power supply?
You should use a USB C PD trigger board for that.
Hai dude can u make an video on Samsung gear vr 2015 model... How to install usb c in gear vr 2015 model
i cant do that with a problem that make me erase the code because ''F5'' was not declared in this scope
pls let me know what type of the buzzer??
Superb. Shame you couldn't get a better close up though. Amazing job soldering those tiny things
I’m the 1000th like I’m feeling so thug life for making it 1K likes
Awesome!
Here I am during the corona time. I have no regrets.
Which 4.7k resistor you used in this video? 1/2W or the 1/4W?
I used a 0603 surface mount resistor in the video, which was probably 1/10W or 1/16W.
Oh no I'm talking about the tan looking resistor on the 2:12 mark?
@@ChampagneThaDonTV Oh sorry, I forgot that I used those. They are the most commonly found 1/4W resistors.
Looks like something from Portal.. That's amazing!
Thanks, KaineRaid! I've only played a bit of Portal so I'm not sure what thing you're talking about. Is there a name I can look up, or would you mind pointing me to a picture of it somewhere on the internet?
@@JiananLi Yep. It looks like this - images.app.goo.gl/XZaJy98zXnRWqtM98. There are 4 wires that retract, ard open up the hatch in 4 quarters.
@@Kanerade Thanks!
WTF
How does the charger know it should only output 5v to the earbuds device and NOT other higher voltages that Type-C can deliver?
Adding those resistors tells it to output 5V. For anything higher, there would have to be a USB-PD negotiation.
Those other higher voltages requires USB Power Delivery (PD) negotiation from the device. Since this cheap 5V device does not have the chip to handle the PD negotiation, the charger won't provide it with higher voltages, but just the standard Type-C voltage of 5V.
@@JiananLi Matthew Stephenson Thank you both. I just watched a similar video uploaded by DIY Perks about a week ago, in his mod he only connects one resistor instead of two, what's happening in that case?
In that case, you get this failure: www.theverge.com/2019/7/10/20688655/raspberry-pi-4-usb-c-port-bug-e-marked-cables-audio-accessory-charging
@@matthewstephenson1664 That's very informative, what a real world fuck-up.
Could you not make an inline usbc female to usbc male cable attachment that'll do the conversion or would that destroy native usbc devices?
Yes, it would be a bad idea to use the adapter attachment that you proposed with spec compliant devices, as they already have those pull-down resistors in place, so the additional pull-down resistors in the adapter reduces the effective resistance in half, thus violating the spec.
@@JiananLi very annoying, would still be good to have a smart inline device which would detect the resistance and either apply or remove the resistance for usbc Vs usbb devices. It's too much pain to convert existing devices by disassembly and soldering
I hope that is permanent as you would not want to rebuild it again but looks good thanks for the video
note f5 error is showing
Great video. Although I don't charge Type C to C regularly, I had noticed this issue as well and I think it needs to be highlighted more as I suspect many OEMs are cheaping out on USB connectors assuming people mainly use Type C to Type A. The ESR seems to be the same basic shell and charging case as my Astrotec S60, but the S60 has balanced armature drivers and wireless charging.
Funny thing is the only thing stopping it from working is two 5.1k ressistors
Good job! I can confirm that this also works to convert a micro USB device to usb-c as I have done that with a Jabra speakerphone. The only downside is that usb-c will only provide 500mA in these configurations, which can be slow for some devices.
Shouldn't it be possible to just lower the resistance then for more amps?
@@Menalix No, the resisters are actually just there to show the power supply that the device wants usb 2. If you want more current without a micro-controller you need to short the data lines with a low ohm resister as well, to show the charger that is ready for USB BC 1.2 and then it will raise to 1.5a
Ohm resistors?

the arduino sketch is not recognizable this line " else if ( não ledOn) {". How should I proceed?
Это просто ахуительно! Я буду собирать на базе старого синтезатора.
Just put some bacon and it is done Sorry for the bad jokes i am typing this at 2 am
La la la la +1 pls
Good man..
Amazing work.
5:45 thank me later
Add black mate film on top of matrix, so that everything is black, but only active pixels shine trough.
:)
awesome
i love the clear of the jumper wires. everything looks clean and nice
