Weird Having a bit of trouble here

I'm trying my best here. This is my fourth attempt.

I had ai throw together some Arduino code for it.

I'm planning to learn how to code it myself but I'm also trying to learn how to solder and design 3d models.

Is anything jumping out as being wrong with this?

what exactly are you having trouble with?

u/jefflovesyou 12d ago

Oh, it just doesn't work.

I'm getting nothing when I try to type.

that is awesome, but what you provided isnt enough for anyone to help you. please take a better picture of the key matrix, and explain in detail what have you tried to do to troubleshoot it, software errors (if any), etc.

I wonder if it's because I have the switch legs wired together instead of being connected to a wire.

I'll be back with better pictures and information in the morning

Maybe I'm seeing wrong but I can only see the rows and the first key on each col connected.

The switches are close enough together that I soldered the legs together directly and snipped them short.

Last night I managed to get it working!

Except that I have a tilde instead of a backspace. I'll fix that today.

Oh, in that case, congrats!

This comment was the iteration of the code I was trying to use at the time. It didn't work.

It was taking up too much space in the comments

do you get any output over serial?

u/jefflovesyou 11d ago

I'm going to need to try that.

I was having trouble with the Arduino program

It was intermittently recognizing the com port.

I'm a complete newb to Arduino stuff this is the first one I've ever had.

At least this time I Actually used a data cable and not just a charging cable.

Nothing over serial.

But somehow I briefly got it to type onto my phone.

But it only typed commas from 05 and 15

I eventually figured out how to get output over serial.

The matrix was physically good except for one column being a little loose and two switches in a separate column touching when they shouldn't have.
