PhoneIoT allows you to connect to NetsBlox (https://editor.netsblox.org/?), a block-based educational programming environment, and remotely access your iOS device's sensors and display from code. Along with some of the other distributed computing services available through NetsBlox, this allows students to create highly engaging projects, such as turning your iOS device into an accelerometer-enabled remote control driving a virtual or physical robot rolling around on the ground (via the pre-existing RoboScape service on NetsBlox).
