I am trying to do USB keyboard interfacing with arduino UNO. I would like to take input in the form of ascii values. How can i do it?
Thank you for answering my question. But i figured it out that we could use a female USB connector and connect the data pins with the pwm pins and further use the PS2Keyboard.h library to read input.
The newer 32u4-based Arduino boards (such as Leonardo) support a native Mouse and/or Keyboard integration. For the Arduino Uno you will need extra libraries/firmware to realize a HID keyboard. You can find several approaches and libraries on the web (e.g. Arduino HID Project 2.2, Turning an Arduino into a USB keyboard and so on. Search "Arduino Uno as HID keyboard").

I'm looking for Microntroller (something like ARM Cortex M4) that will have Bluetooth and CAN support. ST has a lot of Bluetooth or CAN chips, but none has both together...
We would like to avoid two chip design...
Thanks.
I did some brief research:
NXP KW39. This would be an M0+.
Renesas RA4W1 is a M4.
Silicon Labs have lots of Bluetooth products but I didn't find one with a CAN controller - I didn't look that carefully though.
ESP32 has both Bluetooth and CAN (they call it "Two-Wire Automotive Interface").
Here is a link to the datasheet: https://www.espressif.com/sites/default/files/documentation/esp32_datasheet_en.pdf
Hoping someone can point me in the right direction as I need to develop a simple 2 button bluetooth device that acts as a 2 character keyboard when paired.
( tried repurposing camera shutter devices but to no avail).
What would be teh best suggested development system and chipset for such a simple device ?
Thanks

Do you know if Apple's keyboards use same usb coding as in this pdf:
http://www.mindrunway.ru/IgorPlHex/USBKeyScan.pdf
If not, then could someone post proper coding table for apple's usb keyboards?
Thanks
I would assume that Apple's keyboards work with non-Apple computers, so they should implement the standardized USB Human Interface Device (HID) specification. The key codes for that specification are found in the HID Usage Tables, table 12:

The task at hand is to integrate/interface an already existing ultrasonic sensor like this one to a Z-wave transceiver.
Here are the questions related to it:
Is it possible?
What all do I need for it? (Hardware + Software)
Are there any examples that i can follow?
If this sensor is Arduino compatible, you can have a look ar the Z-Uno project.
Their product is an Arduino compatible Z-Wave board, which you can program from Arduino IDE and use as a Z-Wave sensor/actor.
I am sending serial data to my raspberry pi from my arduino then converting the serial data to MIDI using this program: link. Is there any program out there that will take the midi input from the converter program and send it out the pi's audio jack in real time?
I've been using fluidsynth as a softsynth. I haven't run any on the pi, though. There's also a lot of others like amsynth, hexter, xsynth-dssi etc and some of them might be more suitable than others.
You might try running apt-cache search with some suitable keywords and look for programs available on the pi.
