Top 10 Arduino library authors @arduino @arduinolibs #arduino

Arduinolibs

Over 8 years ago I wrote an article about Arduino for Make: Magazine, later Adafruit manufactured Arduino’s in the USA for awhile when Arduino was 2 separate companies (we only worked with Arduino.cc) – during that entire time Adafruit has been one of the most active authors of Arduino libraries and still is to this day. It’s been about 10 years of writing, testing, and releasing open-source code for Arduino.

Adafruit will be doing an Arduino day event Saturday March 16th at 8pm ET. Leading up to that, I wanted to see if there was a way to know which libraries of ours are used the most. Turns out, there does not seem to be a way to know the number of downloads of a library. I emailed the Arduino developer list, I’ll post any updates if there are any.

What you can find out are things like the total number of authors, libraries they have, and a few more things – the site arduinolibraries.info displays what is available (GitHub here).

Here are the top 10 Arduino library authors as of March 11th, 2019 9:00 PM EDT.

  1. adafruit: Adafruit Industries 168
  2. sparkfun: SparkFun Electronics 88
  3. seeed-studio: Seeed Studio 58
  4. arduino-libraries: Arduino Libraries 52
  5. stm32duino: STM32duino 45
  6. pololu: Pololu Robotics and Electronics 34
  7. paulstoffregen: Paul Stoffregen 25
  8. faboplatform: Fabo 24
  9. hideakitai: Hideaki Tai 23
  10. luisllamasbinaburo: Luis Llamas 21

The are a total of 2,081 libraries and 864 authors.

The way arduinolibraries.info works is that it gets the JSON file (https://downloads.arduino.cc/libraries/library_index.json) from the Arduino Library manager and uses the information there to match up what is on GitHub and display it on the site. It generates a static site, clever way to display things, there is also a Twitter account that tweets out new libraries and updates too: @arduinolibs.

I poked around the JSON file and saw that the libraries are stored on Arduino’s servers, for example here’s one ours – Adafruit_NeoMatrix-1.0.0.zip, so that means there are some logs or stats somewhere that could also be displayed for the developers and community to know which libraries are downloaded the most, and which ones to make sure are updated and worked on if they are popular.

Aday2018

Arduino has the number of downloads of the IDE and users to the site, so this is something that arduino likely has and would be really useful for developers and the community. Image above is from Arduino Day 2018 (video).

Update: March 14th, 2019 3:30pm EDT – Post up this question/request on the Arduino “AMA.”

The creator of https://www.arduinolibraries.info/ is also willing to add them to the site as well.

Update: 3/15/19 platform.io has the number of downloads, more details here via Twitter.
