Ray has built nice water valve controller that fit into mint tin. The minty project based on Arduino pro mini to control orbit yard watering valve. It uses RF link 434MHz transmitter and receiver module for wireless control. As power source, the project comes with single 3.6v li-poly rechargeable battery. Since the valve solenoid need [...]

This wireless temperature sensor is developed based on PIC12F675 microcontroller. The project is equipped with DS18B20 1-Wire temperature sensor and Sure TTL Bluetooth Module.

The advantage of using Bluetooth than Xbee module is that no custom hardware is required on the receiving end and almost all modern laptops have an integrated Bluetooth chipset, so no more [...]

This low-cost stripped down mobile payment system features Radio Frequency Identification (RFID) for identification, 4-digit security pin authentication and Ethernet Data Transfer. The ATmega32-based project prototype is intended for a low-cost secure payment system that has the potential to change lives in rural areas of developing countries.
