SpaceX now advertising Swarm satellite IoT connectivity on its Starlink network

SpaceX bought satellite data start-up Swarm, in a rare acquisition by Elon Musk’s space company over a year ago. SpaceX is now advertising Swarm satellite Internet of Things connectivity on its Starlink website, with IoT service at $5 per month. - Adafruit Blog

Starting today, November 15th, 2022, all new Power-Ups in IO for the weather service will be using Apple’s WeatherKit weather service.

Dark Sky has been deprecated and will be shut down on March 31st, 2023. All existing weather integrations will continue to work until that time.

We recommend that prior to that deadline you migrate your existing weather integrations to the new WeatherKit weather service.

The steps to create the integration are the same, and we will automatically default to the new service for you.

If you need help migrating your client code, Apple has a Transitioning from Dark Sky section that provides field mapping data from Dark Sky to WeatherKit.

As always, if you have any suggestions or bugs to report about this update, please let us know in the forums.

The Adafruit IO team just released an update for Adafruit IO and the No-Code IoT Firmware, WipperSnapper. This update brings the ability to control the position of a servo motor from Adafruit IO, without writing a line of code. Servos may be used in any IoT projects where you need to physically display a value or to open a door/window/lock.

Combine Adafruit IO Actions with Servos for Rule-based IoT Projects

We also enabled control of a servo motor from an Adafruit IO Action. For example, the Action below tells a servo to write a pulse width of 2500uS if the temperature sensor (also connected to a WipperSnapper device) is greater than 70 degrees Celsius. The servo could be attached to a door, and open it if the temperature is too high.

How we implemented servos in Adafruit IO

The Adafruit Shop stocks many different types of servos that can rotate 180 degrees (90 degrees in each direction). While most (standard, non-continuous) servo motors generally adhere to “default” servo pulse widths provided by the Arduino library (1ms to 2ms), it’s possible that the defaults may not give you a full 180 degrees of motion. Instead of setting the angle of the servo, Adafruit IO’s servo support includes a “Generic Servo Component” that lets you set the minimum and maximum pulse width for your servo, in uS. Further - if your servo uses a non-standard frequency (anything other than 50Hz), it can be changed from here.
