Adafruit Weekly Editorial Round-Up: November 25th – December 2nd
ADAFRUIT WEEKLY EDITORIAL ROUND-UP
We’ve got so much happening here at Adafruit that it’s not always easy to keep up! Don’t fret, we’ve got you covered. Each week we’ll be posting a handy round-up of what we’ve been up to, ranging from learn guides to blog articles, videos, and more.
We’ve got tons of projects, libraries and example code for CircuitPython on microcontrollers, and thanks to the flexibility and power of Python its pretty easy to get it working with micro-computers like Orange Pi or other ‘Linux with GPIO pins available’ single board computers. CircuitPython will be instantly and easily runnable on Linux computers like Orange Pi AND Thanks to libgpiod and Armbian we now have CircuitPython GPIO/i2c/SPI/UART for over 110+ CircuitPython libraries!
Welcome to the seventh and final guide in reef-pi series. In this guide, we’ll learn how to use reef-pi to build a dosing controller. This guide assumes you have familiarity with reef-pi, if not start by reading the first guide in this series.
Dosing controllers, or dosers as they are popularly known, allows automated addition of liquid in reef tanks. These liquids can be chemical reagents aimed for maintaining a certain type of chemistry (such as optimum calcium or alkalinity levels) or microbial population (such as phytoplanktons or nitrifying bacteria) inside the reef tank.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
