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.

SOP Arduino-compatible MCU?
They're compatible with Arduino by using the megaTinyCore and programmed with an UPDI programmer. A homemade UPDI programmer can be made with a USB-Serial adaptor and a Schottky diode (instructions on that site).

Best way to migrate from an arduino-based system to a purely microcontroller-IC one?
Programming is done via the Arduino IDE, although NOT all libraries work. See: https://github.com/SpenceKonde/megaTinyCore/blob/master/megaavr/extras/LibraryCompatibility.md

I got an ATTiny1616 development board. How do I connect the two and flash the code (basic blink example) from the Arduino Nano to the ATTiny1616? Thanks.
Go check the site for the Arduino megaTinyCore which includes amongst other things instructions on how to make a programmer for that kind of ATTiny microcontroller (the so-called "modern" attinys).

Interested in a MIDI-capable relay bypass?
So this megaTinyCore GitHub page talks a lot about the programmers and various ways you can flash to these chips. I basically used 3 male header pins (vcc, gnd, updi) connected to a modified serial programmer that I insert into pads on the board. Crude but honestly pretty painless and effective.
- Used an Atmega328 with Arduino optiboot years ago — is this outdated?

question about choosing the right microcontroller for a small LED programming job.
You can program them with Arduino using the MegaTinyCore and you upload programs to it using the UPDI protocol which uses just one wire. You can make a programmer for it with with a Serial-USB Adaptor, a schottky diode and some wires - all the instructions in the link above.

I need help understanding pin naming notation for bit-bang applications...
Yeah, do a quick search for PIN1_bm in this file https://github.com/SpenceKonde/megaTinyCore/blob/master/megaavr/extras/ioheaders/iotn412.h
- megaTinyCore is missing?

Cheap ADC / alternatives to ADS1115/ADS1015
The modern line up of ATtiny micro controllers is pretty sweet. They go for under a dollar a piece on digikey (best place to get them). They are mostly surface mount so an ebay smd adapter board kit makes them easy to use. I picked the attiny1604 but there are many variations. This is the arduino core for them and if you scroll down has all the info and variation comparison. https://github.com/SpenceKonde/megaTinyCore

Attiny 1626 Issues with 18B20 temperature sensor
I am programming the Tiny via UPDI through a Arduino Nano using the Arduino IDE with the MegaTinyCore. It does verify the code after upload. I can use a 1306 display (I2C), and manipulate all the GPIO's with no issue. I can use the same GPIO that I have hooked the 18B20 up to for anything else, just not 1-Wire. I have tried other GPIO with the same response. I am using the example for the Dallas Temperature and update the pin assignment. The exact same code works fine on a 328P with the same sensor, so I dont doubt it is a library issue but I'm not experienced enough to figure out exactly where the issue could be.

Alternative for arduino
Resources I used: - How to Burn ATTiny85 Using Arduino-Mega As ISP : 5 Steps - Instructables - To program Arduino as an ISP. This was for my Arduino mega. There are a more than a few links for "normal" Arduinos if you google a bit. - GitHub - SpenceKonde/ATTinyCore: Arduino core for ATtiny 1634, 828, x313, x4, x41, x5, x61, x7 and x8 - arduino support for attiny microcontrollers.

Using FastLED with ATTiny85 (Adafruit Trinket 5v)
Using this ATtiny85 board support building the 20 LED variant of the blink sketch in the Readme I get:
- ATTiny85 timers
- Library for attiny26

Hi there i need help programming this ATTINY 85 board details in the comments
Install ATTinyCore package by Space Konde (author in video is using it). More info on ATTiny core github.

ATtiny85 + IR2110
The Arduino core (i.e. the Arduino libraries) for the ATTiny85 (and a couple more ATTinys) is here and you can find the link for the ATTiny85 specific information a bit down the main page which, inside, includes this excelent refence picture.
