NEW GUIDE: ePaper Calendar with the Metro M4 Express Airlift + Tri-Color ePaper Shield #AdafruitLearningSystem #ePaper #Airlift #Adafruit @Adafruit @Cogliano
Build this calendar display using the Adafruit Metro M4 Express Airlift and the Tri-Color ePaper Shield.
A wonderful thing happened when the Metro M4 Express Airlift was released. It opened Arduino sketches to the Internet, freeing them from the confines of their closed environment. It is now officially a “thing” in a world of the Internet of Things (IoT). For this project, the sketch utilizes the built-in Airlift coprocessor board of the Metro M4 Express Airlift to grab the current date and time from Adafruit.io. No Real Time Clock (RTC) is needed here, since Adafruit.io will happily give us the current date and time, and in our local timezone too.
The Adafruit Tri-Color ePaper Shield used with this project is a 2.7″ ePaper shield that displays black, white and red pixels. It easily connects to the Metro with no soldering needed since the headers are already assembled on both the Metro and the ePaper shield. The sketch displays the current month using the date and time pulled from Adafruit.io. The ePaper display keeps its display even when power is removed. Once a monthly calendar is displayed, you could unplug it and the display will continue to show the calendar.
A simple, no-solder project with great eye appeal and usefulness.

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.
