Android Things, The IoT Platform for Everyone

Ever wanted to try Android Things? Have you been intrigued by using Android for IOT? Visit this workshop! We will have Android Things Devkits including some cameras, buttons, LEDs, fans and more.

We will build a collective display and display a message together using buttons.

Never worked with hardware before? Don’t worry, we will help you to get up and running in a few minutes.

We will also talk about connecting Firebase to your Android Things application.

You will need your own laptop for this workshop. Please have an up to date Android Studio installed, update your SDK to at least API-Level 26 (AndroidOreo) and have a look at https://developer.android.com/things/preview/index.html Hardware setup will happen during the workshop.

1. Android Things The IoT Platform for Everyone Nicola Corti @cortinico nco@yelp.com Michael Langer @mchllngr dev@michaellanger.me Jossi Wolf @fleischwolf13 jossiwolf@gmx.net
2. Please start downloading this file… bit.ly/devfesthh-iotimage And Android Studio in case you don’t have it ;)
3. What is Android Things?
5. Cameras Gateways HVAC Control Smart Meters Security Systems Smart Doorbells Routers Energy Monitors Point of Sale Inventory Control Interactive Ads Vending Machines Asset Tracking Fleet Management Driver Assist Predictive Service Use cases
6. Any other Android library... Android SDK Play Services Firebase Android Studio Cloud Platform Similarities
7. No Play Store Deploy OTAs Subset of APIs Custom Hardware Single Purpose Device Differences
8. Consider Alternate UI Displays are Optional

13. Android Framework Hardware Libraries Linux Kernel Managed by Google Apps User Drivers Managed by Developers Shipping with Google
14. The Android Things Console
18. Developing for Android Things
19. NXP I.MX7D Raspberry Pi 3 Developer Kits
20. The DevKit 1. Pico i.MX7Dual development board 2. Standoffs (x2) and screws (x5) 3. Rainbow HAT 4. USB-C cable 5. Wifi antenna 6. Antenna extender cable 7. Camera module 8. Camera module cable 9. 5" multi-touch display 10. Display 6-wire cable
21. The Rainbow HAT • Seven APA102 multicolor LEDs • Four 14-segment alphanumeric displays (green LEDs) • HT16K33 display driver chip • Three capacitive touch buttons • Atmel QT1070 capacitive touch driver chip • Blue, green, and red LEDs • BMP280 temperature and pressure sensor • Piezo buzzer • Breakout pins for servo, 12C, SPI, and UART (all 3v3)
23. Electronics 101
24. Broadboards • Construction base for prototyping electronics • Useful since they are solderless • Either big or small available
25. Jumper Wire
26. LED Emits visible light when an electric current passes through it
27. Buttons Allows electricity to flow between its two contacts
28. Resistors Used to reduce current flow
29. Sensors
30. Pico i.MX7 Pinout
31. Peripheral Driver Library - Github + many more... bit.ly/androidthings-github Button GPS PWM Servo RGB LED Strip Temperature Sensor Capacitive Touch Buttons Peripheral I/O - Low Level Access GPIO PWM I2C SPI UART I2S Hardware Access
