It means the pin can be a PWM output for use with analogWrite().

You wrote: ftin = feet*100 + INCH; What is this monster? I am not very familiar with imperial units (and I wonder why anyone would still want to use them), but I believe a foot is not 100 inches. Oh, I see. The monster is a kludge to manage the display in feet & inches. But note that it is computed at every loop iteration as a function of the measured ...

It is indeed possible and also without the requirement to modify the Arduino environment itself. Just register an HID descriptor for the "report ID" for "Consumer Control" (the code is 4 (constant kHID_ReportID_ConsumerControl), where the "report ID" code for keyboard and mouse are 2 and 1, respectively): static HIDSubDescriptor ...

Uno's Mega's and so on have a separate MCU (u3) that contains the boot loader and is responsible for the USB connection and for driving the virtual serial port. Micros ( and also Leonardos and Esploras ) have built in USB support in the main MCU (u4). So if your program does something that breaks the USB part of the MCU the communication breaks also. This ...

I experienced the same frustrating issue for days. It was Ubuntu. The fix was also so easy: sudo apt purge modemmanager Until I discovered it, I suffered headache for days.

I have successfully solved this a year ago and I am trying to remember how I did it. So while it's fresh in my head this thing has to do with the bootloder. The first and most obvious thing you can do is try to doubletap the reset and ground contact. Double tapping it will force the Arduino to reset and start in the bootloader for 8 seconds. This is how I ...

Don't do serial prints inside an ISR. Your variable enable should be declared volatile as it changes inside an ISR. The compiler is entitled to cache the variable value if you don't do that. You are inconsistent in your use of enable. You test for LOW or HIGH but set it to 0 or 1. Now they happen to be the same, but someone might wonder. If you are going ...

There is an Arduino Xbox 360 (XInput) library. But I do not use Steam so I have no idea if this works. https://github.com/dmadison/ArduinoXInput

It was wrong of you to try and install the driver as this board SHOULD be recognized as Leonardo. I would try to reinstall the Arduino IDE, it will also reinstall the drivers (hopefully)

The wireless medium you choose is largely irrelevant. The important thing to realise is that it's not (in most cases) the wireless medium that is communicating with the computer. Most wireless mice use the nRF24L01+ (or rather the integrated SoC equivalent) to communicate. They use a USB dongle plugged into the computer for that communication. The computer ...

Your problem is most likely the use of SoftwareSerial for your VR module communication. SoftwareSerial is notorious for breaking things. It disables interrupts, and hogs the CPU. You should be using the hardware serial port instead which, on the Pro Mini, is completely separate to USB communication.

You can read the Arduino's supply voltage see here How to measure the supply voltage of Arduino without using an analog pin Alternatively use the internal 1.1V reference and a suitable voltage divider to read the lipo's voltage

You mustn't terminate a #define with a ;. Semicolons are for C and C++ statements. #define is a preprocessor statement. #define creates a literal string replacement, so when you use it you end up with: const char keymap[5;][6;] = {... which is, of course, wrong.
