Thanks for the replies, and my apologies for the duplicate thread. I have a lot into this project, and it represents my first foray into microprocessors and Arduino coding. As I learned to do all...

I started developing a bluetooth capable vintage manual typewriter using the Arduino Leonardo. I redesigned the installation using a Teensy 3.2 because I was able to pack everything into the...

Thanks for the quick response, but neither of those worked. The odd thing is that this works with the Leonardo and Keyboard.h, but not the Teensy. Anyone know what's up?

Hi,

I've started using a Teensy 3.2 instead of a Leonardo for my project. All is working well, except for the fact that the Teensy won't send arrow keys (up,down,left,right) with the same Ascii...

The last time I coded anything was a billion years ago in Basic. I've been learning Arduino for a project I'm working on using a Teensy, but I'm stuck. The sketch shown here is cobbled together,...

You may be right. I have just enough knowledge to question the possibility of it all now that I know more. Someone with a lot more expertise than I have, with an oscilloscope, might sort it out.

It had occurred to me that the typewriter might be acting like a big antenna -- but I knew very little about analog inputs at that point or the sensitivity to noise. I've since learned a lot! Your...

Yup, tried that. As I understand it a low pass filters out extraneous noise. I may not have had the capacitor and resistor values totally tuned in, but I was in the ball park. Remember that I've...

Hi All,

I've been working on a project building a sensor system to read the keys on a conventional manual typewriter (like but differently than usbtypewriter.com). I am specifically building for...

Thank you! I'd forgotten that I'd found what I needed in a midi article! That's not my application, but it includes what I needed. You've saved what's left of my sanity.

Silly issue here: There is a great how-to article on the pjrc site about using a 74HC4051 shift register to expand input ports to the Teensy. I accidentally close the tab and can't find it now to...
