This instructable describes how to make a DIY GSM phone using Arduino Uno and GSM/GPRS shield. The project uses a TFT LCD with touch screen to provide an user interface required to operate the phone. This Arduino phone can receive & send message, dial & answer phone calls, and display real time clock.

Here’s a very nice digital alarm clock using Arduino and VS1053 MP3 decoder board. VS1053b is a single-chip MP3/AAC/-WMA/MIDI audio decoder that contains a high-performance, proprietary low-power DSP processor core VS DSP4, working data memory, 16 KB instruction RAM and 0.5+ KB data RAM for user applications running simultaneously with any built-in decoder, serial control and input data interfaces, upto 8 general purpose I/O pins, an UART, as well as a high-quality variable-samplerate stereo ADC (mic, line, line + mic or 2×line) and stereo DAC, followed by an earphone ampli?er and a common voltage buffer. This project uses 128×64 GLCD

This project describes an Arduino-based FM transmission using the KT0803K Digital Stereo FM Transmitter Radio-Station-on-a-Chip. The KT0803K device is designed to process high fidelity stereo audio signal and transmit modulated FM signal over a short range. It features an on-board 20-bit audio ADC and supports standard I2C interface for frequency setting and power control. The project uses the Nokia 5110 GLCD for display and a potentiometer for varying the frequency of FM transmission.

This instructable describes an Android application named Andruino that can be used to control an Arduino board from an Android phone. It’s both an Android app and an Arduino program, and provides a simple user interface to control Arduino’s digital and PWM, send text commands to Arduino, and receive data from Arduino over Bluetooth serial using the popular and inexpensive HC-05 Bluetooth serial module.
