MAX471 Current Sensor | Cheap Electronics
I’ve never seen a hard drive with one head… and you crashed it
you need to put a hole in the cover where the hole is on the original cover so the air can flow properly.
awesome thanks, just what i was looking for
is it hard to make one by just following what you did and copy pasting the codes you've provided? I don't have basic knowledge about arduinos :3
still needs the seal made on the transparent hdd cover bro
nope its pata ide
Can you press multiple keys at once? Or is it the function of the diodes?
Without the diodes, pressing multiple keys at once could fry the outputs of the Arduino. Example: at 6:48 if the Arduino is outputting a High on Col0, and Lows on Col1, Col2 & Col3, pressing any key on Col0 would connect that High to the relevant Row input. Here's the bad part: Pressing the top-left switch AND the top-right switch simultaneously connects the High on Col0 to the Low on Col3 through the 2 switches, possibly frying the Col outputs and presenting gibberish to the Row0 input.
Will the arduino uno R3 SMD micro work?
No. Unless you find some software that works over serial and not with MIDI USB protocol
Can I still use the original speakers?
if you find a way to connect the pins to arduino still beeing able to connect them to the original board yes
Can it be done with nanoboard?
do got the arduino code
Hello, I am new to this but your video might help for my midi setup. I got Yamaha PSR 160 keyboard. And the cable inside I got 15 cables all together. Not like yours as 7 and 8 cables separated. In that way, how should I program?
use a multimeter, look for other videos where u identify "keyboard matrix". ask here som1thing idk
Thank you very much 😊
If both analogWrite and digitalWrite have the same purpose like turning on a diode, then why both of them exist, why not to use one of them like analogWrite and ignore the second one?
is there any chance of getting the documentation for this? or the website link please??
Thank you very much for the video. Can you please tell me where I can buy a matrix button like in the video?
One question, will this cheap read voltage levels between 0 to 3 V?
The diodes are there to prevent ghost signals when scanning the keyboard as a matrix. Honestly, I don't know how your circuit is working without them. Unless somehow you unsuccessfully shorted their pins in your wiring scheme, and they are still preventing backflow of the current. Diodes are a necessary part of a circuit like this.
can we do it on citizens barcode printer ?
is it essential to use resistor ladder
Yes, to pull up the keys pins so arduino can read them.
Nice job bro, Can you explain the parameter to change the size of the font when they were printed in the paper, I mean, what's the relation to the height of the font (millimeter unit) and the parameter of your programing code? thanks
Not to waste any more of my time. If you don't know what the diodes are for... and I hit stop. Then I am reading in the comments about voltage steps and a matrix other than 6 which is half an octave. Got to look into Teensy projects not Arduino. You scan a matrix, on or off. By using voltages, dirty or worn contacts will mess up notes. Those single row rubber contacts are no longer made as I know.
Can it be used in the org 2020 application, smartphone
wenn ich treffe kriegst du 6 euro von mir soll ich dir erklären wie velocoped funktiniert wwas fu funkt eigentlich inn deinen henes digga kühe auf der autobahn glaubst du an gott xtc
i looked up this video trying to remember Evan Kale's name hahaha prefect shoutout. What great videos he had
Nice , but no velocity?
Uhmmm... I kinda have a question. Can this circuit be used on mobile phone application? I have some applications that require a midi keyboard
If you find a way to connect via bluetooth or something to the mobile phone (maybe using an ESP32,) then yes, you can.
Another question, which ICs did you use besides the Pro Micro?
Only pro micro, no other ics
can i use other programs?
Yes, that's midi protocol which is compatible with many programs
ty for this clear explanation
can someone explain shorting the diodes and what the resistor ladder does and how I can get one or make one and how also how it's used?
You can purchase the resistor ladder on internet. But if you don't want to, you can simply put normal resistors. The only difference is that the resistor ladder is smaller. Resistors are very cheap.
Good job 👍
Can we connect casio ctk2550 to arduino ? Pls reply
Hi. Most of keyboards are similar, so I think it will be possible
What is the use of resistor ladder?
It pulls up the voltage on keys, so when pressed, it shorts it to ground and arduino can see if it's pressed. Similar to "input_pullup" in arduino
@@GoodElectronics so... If we dont have a resistor ladder, we can change the code to "INPUT_PULLUP" instead, right 😅
@@codewithzi-5817 only analog pins support pullup, so you would need to plan it to have it only on analog pins :)
next time you make a transparent hdd, put a screw on the arm's bearing
Congratulations on the video. I made such a project using parts of an 88 keys sp2x and sensitivity with Midi output. I can use it to control the app on my smartphone. ua-cam.com/video/3PkPAcvJVbE/v-deo.html
bro videos is no loger avaliable :_:
Nice tutorial sir
Its got better accuracy than that for voltage with some calibration and taking an average mine matches multimeter alsmot exactly.
@Good Electronics, I have thermal printer with only USB port, Can you explain me how can I communicate with arduino? WIll it work if I use USB to TTL converter?
No, it's impossible to connect it that way. I have no idea how you could connect it.
@@GoodElectronics Hi, I have bought the used STAR Micronics TSP650 printer with serial port, and also i have ordered rs232 to ttl adapter and conected everything like you, but I still can't get communication between arduino and printer. Do You have idea what could be problem?
Maybe check every baudrate? Or try to swap rx and tx
@@GoodElectronics Thanks for Your reply. I have tried to change baudrates, and swap rx and tx pins, but without any progress. Then I bought USB to RS232 adapter cable to try send commands from Realterm to printer and this works well , so now I'm sure that printer works correctly. Now I'm wondering why it doesnt print when I'm using RS232 to TTL adapter. I am total beginer in arduino programing but as I understand just this two lines of code should be enough to send print request to printer: Serial.begin(9600); Serial.print("Hello world"); So if that doesn't work I supose that maybe my RS232 to TTL adapter doesn't work well. What do You think?
The king is back
Is there any place you can order precut covers?
I don't recommend installing them on a hard drive you use, because all data may be lost that time or in the future. I don't know where you can buy, but you can order cnc milling
@@GoodElectronics Its for a build where everything that can be transparent is transparent. I know it's not a good idea as with HDD as such, but sure would look cool as hell man! ;D Thanks for you're reply and suggestion. Ps. can't remember if u mentioned it in the vid but raptor drives used to have a at least a small window.
great vid! helps alot! but could i use an ESP32 instead of an arduino pro micro for this?
I'm not sure, you have to check if it has native USB support and has arduino midi library
Great Video! can you upload the wiring diagram. i was wondering how your connections were wired.
Hi. In my case half of the keyboard ribbon goes to matrix1 pins, the other one to matrix2 pins. The resistor ladder is connected to matrix1 and I believe connects to gnd. And that's all.
boka choda bolte gad phatchhe na ki ?
Midi Drum for Leonardo Please..
This video becomes the one stop solution for me. Because I want to make midi keyboard (Arduino based) from long time. Thank you so much brother
Thank you I'm understanding the code With feeling
How to make a resistor ladder ? I can't find one.. Also can you share the picture of final version board?? (The main thing is the circuit so its logical to have the picture of it imo) And what board to select on arduino IDE
You can purchase the resistor ladder on internet. But if you don't want to, you can simply put normal resistors. The only difference is that the resistor ladder is smaller. Resistors are very cheap.
I really appriciate that you made this video!
i can not find the code could somone give me the link?thanks
It's in the comment :)
Whats the model of this printer
It's some Epson printer, I don't know the model, I bought it used
@@GoodElectronics thanks also iam ask if you can renewing th link of epson programing guide pdf if you please the old link not working
Unfortunately, I don't have the pdf downloaded and I don't know where to search for the other files, but you can try to search for similar models, for example I found this: files.support.epson.com/pdf/general/escp2ref.pdf Of course most of the commands won't work, but some basic comands are common to all the printers, so they will work.
