The Adafruit IO team has 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 can be used in any IoT project where you need to physically display a value or open a door/window/lock.
Combine Adafruit IO actions with servos for rules-based IoT projects
We have also enabled servo control 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 above 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 store has many different types of servo motors that can be rotated 180 degrees (90 degrees in each direction). While most servo motors (standard, non-continuous) generally adhere to the “default” servo pulse widths provided by the Arduino library (1ms to 2ms), the defaults may not give you a full 180 degree movement. Instead of setting the angle of the servo, Adafruit IO’s servo support includes a “generic servo component” that allows you to set the minimum and maximum pulse width for your servo, in uS. Also, if your servo uses a non-standard frequency (other than 50Hz), it can be changed from here.
As always, if you have any suggestions or bugs to report regarding these new features, please let us know in the forums.
