The aim of this project is to build a wireless 2×16 character display that fit to Altoids tin. It can be used to display data which is sent from the PC using a terminal program such as the Arduino ‘Serial Monitor’.
The project consists of two main parts, first, the ‘remote’ Altoids tin containing Arduino, LCD [...]

AvrPhone is ATmega128A-based simple mobile phone with touch screen and SIM100S GSM module. The display uses 2,4″ LCD with a resistive touch screen and ILI9325B driver (16 bit parallel bus).
The LCD breakout board contains SD card slot and XPT2046 touchscreen controller. They both are connected to AVR’s SPI bus. The project is powered by [...]

This autonomous tracking weather station is built based on PIC 16F877A and SIM900/300 GSM module. It takes (analog/digital) measurements and sends them to a web server over GPRS. It supports up to 3 Analog or Digital inputs. User can make it fully autonomous by adding a battery and a solar station.
