With the new RN-42 Bluetooth module we created a Bluetooth remote control board and transform it into an Android Based system: a board that manages input/output and it’s equipped with four outputs relays and four optically isolated inputs, that can be controlled via Bluetooth. At the software layer, the unit sports three operation modes: manual, […]

We use an Arduino to program other ATmega without bootloader . This technique allows you to use all flash memory for code and make boards using new ATmega, cheaper than those with bootloader. The qualities that have made the success of Arduino are undoubtedly the open-source software, many libraries, a good hardware and a virtually infinite […]

The device is based on a GSM/GPRS module with included GPS. Its main function is to detect and communicate its own geographical position using, on the choice, the cellular phone reference system or the GPS. Its small dimensions are due to the use, for the first time, of a GSM/GPRS module integrating the GPS receiver. […]
