A new guide in the Adafruit Learning System: RGB Matrix Portal Room CO2 Monitor
In this project we use the SCD-30 CO2 Sensor along with a Matrix Portal to drive a 64×32 RGB LED matrix to provide an indication of indoor air quality. This provides a nice way to display the current conditions and have it be readable to an entire room. And as a bonus, with this hardware arrangement, there is no soldering required!
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.
