Open an ADB stream to the phone's shell. Void adbEventHandler(Connection * connection, adb_eventType event, uint16_t length, uint8_t * data) Event handler for shell connection called whenever data sent from Android to Microcontroller You can checkout the source for the Arduino sketch from Github, or just copy and paste the following into the Arduino IDE. Microbridge uses Android Debug Bridge (ABD) forwarding over TCP, rather than the Google Android ADK. The sketch uses the Microbridge implementation by Niels Brouwers. Next, upload the Arduino sketch to the microcontroller. Here is a diagram of the completed circuit (created with Fritzing): Finally, connect the signal lead of the TMP36 to analog input pin A1.
Then connect the ground and power leads of the TMP36 to, you guessed it, ground and 5V. In hardware, this concept is known as a voltage divider. Also connect the same lead through a 10K resistor to ground. Google ADK board, Freeduino ADK board , Seeed Studio ADK board, and DIY Drones ADK boardĬonnect one of the photocell leads to 5v and the other to analog input pin A0. This article will demonstrate a basic thermometer / ambient light level detection input accessory.įor additional background information on interfacing Android with the real world, check out my other introductory tutorials: Sensing temperature and light with Android and Arduino.
