For social distant trick or treating, we thought we’d make a BLE controlled servo claw using the Circuit Playground Bluefruit.

We put our project on this flying ghost prop we got from our local halloween shop.

It moves up and down along a rope that's strung across our porch.

We tied one end to a tree and the other to a lamp post on the side of the house.

The servo is triggered using our mobile phone with the Bluefruit connect app.

This is a 3d printed claw gripper that we designed to hold a small bag of candy.

We think this is a fun way to give out candy that could be adapted for all sorts of projects.

The BLE libraries for Circuit Python makes it easy to control servos using the Bluefruit app.

In the code, the up and down buttons are set up to trigger the servo when they’re pressed.

The angle of the servo is tuned for the gripper so it doesn’t stress out the motor.

In the Bluefruit app you can press the up and down buttons to open and close the gripper.

We think this is a quick and easy way to make a BLE controlled servo project.
