The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Need to learn Arduino Programming Language
If you want to really learn it I'd recommend Bro Codes C guide, that'll make it easier to understand, his C++ guide is a bit longer but once you know C++ it's a matter of going to the Arduino references and looking for the function you need.

help with if statemant!
First, go to the Language Reference, which defines exactly what the commands do.

Best route to start with Arduino?
A great way to introduce yourself to the syntax of C/C++ and, more specifically the various functions and capabilities of the Arduino is to go through the documentation's Reference page on the company's website and read through each function and keyword. By the end of the page you'll have a solid overview of the capabilities of the platform and a certain amount of familiarity on how to use them.

Can anyone help me figure out why this isn't working? Simple: Hello World, ESP32 and LCD
You need a Serial.begin and a Serial.println to see something on the Serial monitor. Have a look at the documentation or some sample programs to see these statements. If you don't have Serial.print statements, nothing will display because you are not asking for anything to be displayed. As for the gibberish when you reset, it is possible these are remnants from an old program. Make sure the value supply to begin matches your serial monitor's baud rate setting (i.e. 9600 from your original post).

arduino pins not working
You might want to have a look at the documentation.

Unusual rotary encoder behavior
If you study the Arduino Language Reference, you'll find |=, <<, >>.

Help needed: I need 255 value when the joystick is tilted all the way forward (for an RC car), but when I’m 50+% forward, it’s already at 255 and stays 255 until I go below 50%. Code is in the video
The arduino documentation is (or was back when i did a lot of work with arduinos) very thorough. Book mark the reference material https://www.arduino.cc/reference/en/ its very handy to have close at hand.

Brand new to coding, just got my first arduino kit. Struggling to understand what I’m doing.
Arduino Reference - Arduino Reference what i usually scroll through to get me through any projects and i started off same place as you not knowing anything about coding and it got me through most of the projects i started. best to just keep making mistakes though and eventually the sketch will compile.

Hello. I do not know electronic circuits well. how can I learn? Can you recommend a source?
You can find what you need to start programming with Arduino on this page: https://www.arduino.cc/reference/en/

Motor hall encoder keeps bouncing its reading even when it's not moved?
Here is my code, I'm using the Rotary.h library from this repository

using PinChangeInterrupt with rotary encoder
Suggest you use the Enable-Interrupt library along with this Rotary Library. Rotary-Lib's example code demonstrates direction detection (in just a few lines).

Can I use more than two optical speed encoders with an Arduino Uno?
https://forum.arduino.cc/t/reading-rotary-encoders-as-a-state-machine/937388 and https://github.com/brianlow/Rotary popped up with a quick google search :P

Help with Pinout on DFRobot Beetle
If you are stuck with no other options, I suggest you try THIS library and its sample Code as a start to getting encoder signals. Then add in detection of the button.
-
Is there a preferred library for rotary encoder on a Nano?
I recommend Rotary library found HERE. It supports Interrupt driven as well as polled methods. Set the Example code HERE for Interrupt and HERE for polled.
-
I need a selector knob
Or you could buy a rotary encoder and use a display with it to read-out how much travel you applied rotationally. Life gets easier using THIS rotary library to detect changes. You get very fast response using Interrupts for the encoder A-B lines (2 Interrupts total). I like the Enable Interrupt library for this.

I'm having problems with counting using a rotary encoder
rotary library (see example code at this link, its super easy)
-
Missing pulses using an encoder
To make life far easier, I recommend using the Rotary library. Just peek at the example and its obvious a lot of heavy lifting is done for you. This includes software de-bounce and the ability to detect rotation rate (aka acceleration).
-
Button box schematics issues.
I recommend the EnableInterrupt library and the Rotary library as one easy way to get encoders up and running.
