In this chapter, you've learned how to build a social and digital photo frame using the Raspberry Pi 3. Although we used Flickr as the social media platform, you can use other social media platforms as well, such as Facebook or Instagram. There are many ways to improve this project. For example, you could display comments along with the photos using the flickr.photos.comments.getList API method.
Chapter 4, Integrating a Real-Time IoT Dashboard, presents how to build a real-time IoT dashboard that can be used to display sensor data, and switch local actuators attached to the Raspberry Pi with Adafruit IO, MQTT, and the I2C serial communication protocol.
