Current technology of mobile Is very popular. And can be applied widely. In addition, Google has developed the Android. This is a new operating system that runs on mobile phones and is open source. This thesis aims tournament slips or electronic learning exercises. You can do a tournament or practice of electronic circuits through the Internet in the software. To facilitate a single mobile phone.
operations, Divided into hardware and software, the hardware part consists of three parts, the integrated microcontroller. Multi-circuit switch (relay) circuit XBee modules of the software programming language on the board microcontroller. ATmega128 microcontroller to control the functions of a digital multimeter. Multi-circuit control switch (relay) in the test arena with a digital multimeter to measure electrical signals through the serial port RS232. Make the tournament without using hand signals measured. To measure electrical signals at various points of the circuit as well.
based on test procedures Results show that the system can not work as intended. By being able to compete with mobile phone on an Android application via the Internet to the extent specified. In the process of implementation, so switching to a showdown on the box, push button switches. The signal and control the wireless arena. In the radio frequency signal, wireless (Wireless) with integrated modules XBee tournament done by the extent of the measurement signal by controlling digital multimeter by the tournament does not require a hand-held wireless signal during the tournament. The error value equal to 0.093% of the total average tournament.
