+## OLED Screen sample for Android Things
+
+This sample demonstrates how to control the SH1106 OLED display using I2C with
+Android Things.
+
+## Pre-requisites
+
+- Android Things compatible board
+- Android Studio 2.2+
+- 1 [SH1106 OLED screen](https://www.elecrow.com/download/SH1106%20datasheet.pdf)
+- jumper wires
+- 1 breadboard
+
+
+# Build and install
+
+On Android Studio, click on the "Run" button.
+
+If you prefer to run on the command line, from this repository's root directory, type
+
+```bash
+./gradlew sample-sh1106:installDebug
+adb shell am start com.leinardi.androidthings.sh1106.sample/.OledScreenActivity
+```
+
+If you have everything set up correctly, you will see a small bitmap slowly
+moving in the screen. If you want to change the pattern displayed, change the
+variable mMode in OledScreenActivity and deploy again. The sample has three
+modes: DOTS, BITMAP (default) and CROSSHAIRS.
