It can replace the cables between different digital devises，and has great application field in mobile phone and computer peripherals. Applying Bluetooth technology into wireless transmission module can replace the data transmission cables in system，and has merits of convenience and flexible application，Besides, it can apply to common occasion it can also apply to factories and enterprises，so it will get great application. This design, which is aimed for the wireless electronic clock, is based on the principle of convenience and low-cost of the utility. This kind of electronic clock can satisfy the market demanding and led the new fashion of the electronic clock as well. Compared with the traditional one, this design, which employing this Bluetooth wireless transmission, has many advantages, such as, it could make the computer control the electronic clock which has solved a lot of trouble that has been made by the manufacture. At the same time, this Bluetooth wireless transmission avoids the complicated connection of the outside liner. The first chapter states the Bluetooth technology, its characteristics and its application as well. In chapter two, the author gives an overview of the practical case of the Bluetooth wireless LED electronic clock system. Meanwhile, the design of the partial hardware circuit, the p
