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

servo-edit

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.
