New Guide: Deep Sleep for CircuitPython @circuitpython
CircuitPython now supports light and deep sleep! Sleep is currently implemented on the ESP32-S2, with more chip families planned. We’ve written a guide about how to sleep, and how much power you can save. Many of our MagTag projects are already using sleep.
If you’d like to maximize the battery life on a CircuitPython project, you need to be able to put your program to sleep when it’s not doing something. For instance, you may want to read a temperature or fetch some data only every few minutes or hours. In between, your board can go to sleep and draw only a tiny amount of power from the battery.
If you’re using a display that is visible even when powered off, such as the e-ink display on the Adafruit MagTag, then you can sleep between updates to the display.
This guide will talk about using the sleep and wake-up alarm capabilities that are available in CircuitPython.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
