The ATtiny85 microcontroller shown in this video is acting as a tiny Arduino board, sending Bluetooth Low Energy packets to an iPhone. The iPhone is using the BLExAR iPhone app to read and parse the data send via Bluetooth.
The ATtiny85 is an 8-bit AVR microcontroller and is particularly applicable for small scale projects in the Internet of Things (IoT) world due to its low power consumption and tiny 8-pin profile. The ATtiny85 will be paired with a Bluetooth module and interfaced with a smartphone to create a connected device capable of communicating information back and forth through Bluetooth Low Energy. Temperature and humidity measured by the DHT22 sensor will be read by the ATtiny85 and transmitted to the smartphone by via the Bluetooth module.
