Arduino bluetooth transciever. Documentation:hardware:devices:acr122 [libnfc.org - Public platform independent Near Field Communication (NFC) library] Controlling Arduino Using Android. The article provides some basic information on how to use an Android device to read sensor values from an Arduino, that too with the help of a low cost bluetooth serial device.
Read on to know more about this. The circuit mentioned here uses python as the scripting language. Controlling Arduino Using Android. The World Famous Index of Arduino & Freeduino Knowledge. Contraptions - Contraptor. Click here to edit contents of this page.

Of course, technology has kept on following a general downsizing tendency. This is what makes the development of a project like this very important. Creating a transmitter using just 2 pieces is quite a breakthrough. The main component of the transmitter is an 8-pin AVR microcontroller. Arduino: The Documentary (2010)
Magnetic Field Sensor Board. • Uses a 3A Hall-effect sensor (UGN3503)• Provides a voltage output that is proportional to the applied magnetic field • Sensitivity: 1.3mV/Gauss• Interface with microcontrollers and logic circuits• Inex Standard 3-pin PCB connector• Compatible with Inex controller boards The Inex Magnetic Field Sensor works with a built-in 3A Hall-effect sensor (UGN3503) which tracks extremely small changes in the magnetic flux density.
This sensor provides a voltage output from 0 to +5Vdc that is proportional to the applied magnetic field. If no magnetic field is detected (0 Gauss) the output voltage will be 2.5V. The voltage output can be calculated using the following formula: Arduino Serial Servo Control.
