耗電量（續航力）測量，計時，開始！
費用：台幣約 150元（3.3V MCU, Bluetooth V2 module(NTD$ 90), duel amplifier IC, 兩顆 3AA 電池, 電容，電阻，8MHz crystal oscillator）
It's begin for battery energy consuming test. It costs around 5 USD, including a 3.3V ATMega 8AL MCU, CSR BC-417 Bluetooth Version 2 module, a duel amplifier IC, 2 3AA battery, resisters, capacitors, and a 8MHz crystal oscillator.
After test, 3 days will eat out of 2 1.2V chargeable battery energy. It maybe causes by Bluetooth Version 2 module or the MCU not put into sleep mode.
