DIY Arduino trackpad

[@sadfatty3371]

Could you possibly make updated code? People are reporting that this is just acting as a directional scroller, rather than an actual trackpad. Could you please try to make new code?

[@sarthakmehrishi3375]

I wanna build a laptop for kali linux using raspberry pi. I really appreciate your idea and hope it helps other in need of advice like me who are new to hardware stuff.

[@SSnoWHand]

Neat! A fellow South African published on Hackaday!

Hello from Cape Town!

[@pompshuffle562]

You can buy a ps2 to usb adapter for pretty cheap even as low as 2 bucks if you're willing to have it come straight from china. Just make sure you get the kind with both a purple and green end going into usb. The ones that only have one green end are passive adapters for things that support both ps2 and usb internally.

[@charliebrownau]

I was thinking the same, some great cheap raspi hdmi lcds around and some great alt offerings for raspis eg LibreBoard and Orange pi

[@jimbobbyrnes]

you can use a touchscreen touch panel instead and the pinout will be easy. so you can use a old phone instead of a old laptop then use existing touchscreen libraries to run it. although finding one that you can easily solder might be a issue.

[@GingerNingerGames]

I've been looking to do this for a few years and didn't even think of this, had a track pad on standby for quite some time, but I think I should grab a better one, I have plenty laying around. Going to use a Teensy though because they're cheaper. I think.

[@CirqueCorp]

We sell trackpads so you wouldn't have to salvage one. Usually we sell in large quantities but I'm sure you could buy a sample unit if you call our sales department. We offer both USB and PS2. We also have an Arduino based development kit with 2 circle trackpads. You can get them at www.cirque.com/circle-trackpad-dev-kit.

[@KangJangkrik]

Today, you can use STM32 instead, it has HID support out of the box

[@MrBullet2]

i have found newer laptop trackpad its LAN 20111B-041108 Rev. A can anyone help me to find the right pins?

[@zklinski]

Thank you so much for the great tutorial!! hope this works XD I just ordered all the parts!

[@chinmayshalawadi1]

Neat!! I was thinking of doing something similar :D

[@BuildItnow]

What were you thinking of doing?

[@chinmayshalawadi1]

Build It Umm , an HID device using arduino . A small panel for music and volume control on a PC . Usually Keyboards have those built in but mine doesn't. Also I can Make it wireless and add more functionalities . So yea , it's on my to do list for videos 😁

[@sohamcpatel]

Great DIY Project. I have a savaged trackpad and would like to make use of it. But have trouble finding pinout. Could you help me with this. I have a ALPS 56AAA1963B.

[@Twometer]

I don't know if you still need this but pinoutguide.com/Inputs/alps_touchpad_pinout.shtml here is the pinout

[@GreenwooddPop]

Don't know if I'll use this in project, but great video nonetheless! 👋

[@BuildItnow]

Thanks for watching!

[@miniclipet4]

Cool idea but if you flash the rom on the arduino uno you can make is show up as any device you like. I have mine used as a keyboard.

[@BuildItnow]

You were able to get an Arduino Uno to show up as an HID device by flashing the Rom, I didn't this was possible. Id love to know how you did it.

[@rayedfarhad8431]

the link you provided in the instructables for ps/2 library does not exist. Can u link the library files? And I downloaded a ps2 library but it shows an error while compiling and i selected the correct board "fatal error: WProgram.h: No such file or directory"

[@blabby102]

Same problem

[@blabby102]

Fixed the problem! You just need to rename "WProgram.h" to "Arduino.h" in ps2.h.

[@christophwieser3347]

Hello, nice work! Can you show the code for left and right click? Thanks!

[@TheErraticTheory]

two finger is right click

[@lyesgherbi5862]

Hello , Can we apply this project to Phone ? Thanks for sharing

[@SilentscufflE]

Do you think it'd be possible to make a macro pad that has a trackpad and key/knob inputs going through the same USB?

[@mari2.]

Maybe with a USB hub.

[@DaMu24]

You're lucky that you found the documentation for the specific trackpad that you found, but this may not apply to every single trackpad in the salvageable wild. It's more helpful to demonstrate how you came to the conclusion that these specific pin numbers are what we want.. And above all, Raspberry PI has GPIO pins specifically for interfacing with any generic devices, including the 2-wire or PS/2 interfaces, so requiring a specific Arduino just to have additional processing required is too unnecessarily complicated.

[@delgola9157]

I was wondering with a track pad is it possible to make it Bluetooth and something written on the track pad and it transfer to a smart phone

[@BuildItnow]

+Dilip Gola yes that's possible using the HC06 module

[@delgola9157]

Build It Build It wow u be able to give a explanation on how the set up be, and where would I get the coding for such a project Hc06 Trackpad Andruno?

[@richardlighthouse5328]

How did you get your touchpad to right click and 2 finger scroll?

[@u-lo-l]

I want to know this part, too

[@oguzhanyarmkas336]

do I have a chance to make it wireless? if yes would you please tell me how?

[@Glycheer]

Nowadays it's easy to make it wireless using an esp32 with a Bluetooth HID mouse library or a rn42 Bluetooth HID, back when you asked, only the rn42 option was available

[@anasqai]

If the cursor controller buttons to both be this, then actually no worry of broken button right?, Then this is flat, if it is upside down? U know i imagine smthg like "just a flat piece but usable of same standard". Then no worry of spoilt items.

[@u-lo-l]

How do you detect two or more fingers? I can just detect one finger. just drag and click

[@odriew5014]

Can something similar be done with laptop keyboards?

[@phillaboody260]

As I was watching you build this I was thinking how interesting it would be if this could be made into a wireless track pad. It could have a switch on it where it switched from USB charging and wireless to a wired track pad

[@최은석-f3o]

I can’t find my trackpad’s pin out... (synaptics 920-002034-02 RevA)

[@prabakaran-gk6gf]

i have some problems "ps2.h:11:22: fatal error: WProgram.h: No such file or directory" how to solve this..?

[@blabby102]

You can fix this problem by going renaming "WProgram.h" to "Arduino.h" in ps2.h.

[@unamed_666]

Is it possible to use trackpad from DS4 controller?

[@YakupBilgin]

The library is not working now. Can you help me ?

[@khanhphaminh1175]

Brilliant!

[@noellathemodestmode9579]

what type of laptop did you salvage that from

[@infinitely5812]

U can buy them

[@490o]

How would I find out what pins are what, if I can't find the documentation for my touchpad?

[@x_emraah]

hello sir, where did you buy that box with boxes and green base? (links)

[@BuildItnow]

what box?

[@x_emraah]

Build It ibb.co/iYpUS5

[@Didilebarbu]

Hey OP, I am stuck with the Arduino IDE part: I can't download the libraries. Could you make us an update video for this part?

[@asiordanov]

Amazing! Thank you for the video! Coul you advice me what model of Andruino is it better to use if I have a wireless keyboard with a touchpad and want to make it wired? (for exaple Logitech Wireless Touch Keyboard K400 Plus Black USB)

[@ziome3eg]

I have noname trackpad from toshiba satellite a200 and i can't find pinout :/

[@kanaefukuda1864]

start guessing.

Hey bro i want to have this product.. but like how a skin what i can put it on my track ... how glue ... with wireless bluetooth stick.. can you make it 😅 i buy

[@johansmitphotography]

My laptop still works. Acer extensa 5220. Windows xp

[@espero_dev]

Can I use it with my raspberry Pi 4 or 5 ?

[@loganbyrne3054]

Can this be done with Aurduino Nano? And could it be controlled BT?

[@BuildItnow]

It can be controlled through Bluetooth however like i said in the video it will only work with the Arduino Micro and Leanardo

[@monti64]

I know that many people already wrote about a link missing, or that they aren't able to find the ps2 or mouse library. But I wanted to ask you, if you could maybe upload these 2 libraries, so that this is still possible to do. I would really like to also make a RPi Laptop and making a trackpad is step one and is just awesome by itself because of the theoretical portability ^^ (I couldn't find a link with the wayback machine :/)
