Does the same concept apply to these even older keyboards? The 5 pin din
Comment from : @QuangNguyen20

Wow! I have been looking up how to connect a PS/2 keyboard to my 6502 based computer, and I didn't want my main CPU to have to do the decoding workbrThis is by far the most simple way of getting the ASCII data (and with some tweaks, codes for a few special keys) that I have seen so far brThanks
Comment from : @PhilR0gers

I want to be able to press some key on Keyboard and as result, Arduino should work as a keyboard itself for computer and act as if some other keys were pressed or sequence of keys I want to make such keyboard convertor

Since you've used interrupts and noInterrupts (just macros to cli and sei) you could use attachInterrupt for simplicity (not as fast as with ports, but it's only done once on startup)
Comment from : @InfiniteCoder01

Thanks for a good description and visualization, especially that you explain the reasoning behind it and what would happen if a certain line (eg interrupt flags clearing) wasn't done and what each line does Might have been interesting to see how to handle the parity bit (discard the input if the parity doesn't work out) Also, how does sending commands to the keyboard work (LED setting and others)?

I have a problem, I have a ps/2 usb keyboard with rgb leds, and every time i commect the keyboard to the arduino it open and close after half a second how do I resolve this?brThanks

Would the code work for M5Stack which is a ESP32 based development board ?
Comment from : @trushti_1375

Very informational! Would you mind sharing the model of your ps2 keyboard? I am using one that draws 100mA and it seems like the arduino nano is not able to supply that much
Comment from : @hipposhark

Very good! Very simple and cheap! Did you a same for USB keyboard?

Thank you
Comment from : @engbakeel9735

Me funciono muy bien lo necesitaba para un proyecto, agradezco tu aporte Thanks and congratulations!
Comment from : @chonvalle392

Can you connect it with and display like liquid crystal display or tft display so that it can type letters on it like a small cmd computer
Comment from : @Xavier_Everwhere

Amazing
Comment from : @servetbirgul9526

I will be using this solution for my Z80 homebrew computer that I am currently developing Thanks for showing this up
Comment from : @unilein

Exelent video my friend, y want to use this information to use my keyboard to a midi controller, thank you so much!

Why is your wi and keyboard german?
Comment from : @hallomeinnameistkarl216

is it possible to create a layer? Thank you
Comment from : @gianchf9216

SO COOL
Comment from : @jackjack-kw2zh

Whats would be app or device that you used tô get signal from keyboard?
Comment from : @wsricardo23

hi, your video is very good Does this work kinda similar if I want to get data from a ps2 mouse, like the coordinates ?
Comment from : @johannahoppe5544

can you use it with usb barcode scanner??
Comment from : @Drxxx

Very helpful I'm currently building a PS/2 keyboard interface for an Apple II computer
Comment from : @xotmatrix

Liked and subscribed!
Comment from : @gopro2804

Thank you sir, if i use arduino uno which input do i use for data and clock
Comment from : @karamca3722

I'd love to know how you're using the keyboard to "toggle" data into RAM without an operating system to help it
Comment from : @edgeeffect

Great video
Comment from : @sabinbaral4132

Really surprised how simple both the VGA and PS/2 keyboard specifications are - thanks for making them accessible to everyday humans :)
Comment from : @stupossibleify

Very informative Impressive I want to build some kind of tiny basic computer or VT Terminal using arduino(s)
Comment from : @2150dalek

can you pls show us to use a ordinary gamepad with arduino not ps4 ps3 types just normal ones It will be a great help if you show us
Comment from : @robipaul5762

who the fuck uses PS/2? What about USB keyboard?
Comment from : @sto2779

This is awesome to use with a Leonardo or a teensy, to reporpuse and old PS2 keyboard as a Macro keyboard for shortcuts for editing, for example :)
Comment from : @hkfuertes

muy buenos tus videos, he apredndio mucho y los estoy replicando una pregunta porque no usas las librerías de vgax ?
Comment from : @corcinox

I've checked your completed code and I figured out that you used char array instead of constant char array this will cause ram problem It need to be optimized brRegards
Comment from : @bakialmaci

I try to implement the arduino code at MSP430 I use msp430g2553 I click 'A' letter, and I check the value of 'val' So I got the two different values like that: br0000000011000000bbr0000000011100000bbrbrIs it related with my CPU speech? I check the code with arduino uno that has 16Mhz, it works clearly I think I lose data with msp430 Do you have any idea?
Comment from : @ahmetanbar6346

in your ISR there can be the problem when unplugging the keyboard in time of being just in the routine While loop is not the best way to wait for the clock edge when the keyboard can disconnect any time And the for loop in ISR is to long if there is a second interrupt if you need another input of the arduino with a second devicebrIn the case of no other IRQ you can do as shown The ISR must always short as possible 800 usek or more can be to much

Thanks for this excellent video! I'm trying on my PS/2 type keyboard but this is not working on my implementation brIf I need to give more specific details,br- I've cut the wire and there is 4 color which are RED, BLACK, WHITE and GREENbr- I'm using original Arduino Uno board which has DIP socketbr- RED -> 5V, BLACK -> GND, GREEN -> A3, WHITE -> A4 br- Keyboard Model: Everest KB-517P (Not much knowledge about this model on internet)brbrI am absolutely sure my Arduino working fine and I checked your answers to another comments/issuesbrbrHow can I test my keyboard is working? (Without oscilloscope and PS/2 support)brAnd what do you suggest to me?brbrRegards
Comment from : @bakialmaci

This is not working for me any suggestions
Comment from : @himanshutomar8165

Thank you a lot !!!!!
Comment from : @MD-qz6gk

I feel like this was made for me All the other ones just don't work I hope this works and do you think this would work on an arduino mega 2560
Comment from : @ducksonplays4190

Will this work on an UNO?
Comment from : @ManicQuinn

Jejeje genial amigo, soy nuevo subscriptor, genial proyecto, me cuesta hablar el ingles pero muy buen video, es increíble lo que usted hace
Comment from : @WSSTUDIO-wj6fx

I eventually got around to trying my PS2 keyboard with your code for the Arduino and it works great I've remapped the keys for a US keyboard layout that we use here in Australia I will use it to interface to my CSCvon8 minimal CPU, so it will have native keyboard input rather than through a terminal emulator and UART that I am using at the moment Many thanks!

Excelente vídeo !! Thanks and congratulations !!
Comment from : @sandrosalessales6324

Well that makes a lot more sense! I was trying to read the data and clock continually and getting garbage
Comment from : @colonelbarker

This is great timing as I was just about to try hooking my PS/2 keyboard to my Arduino Nano and see if I can interface it to my CPU
