The DS1302 trickle-charge timekeeping chip contains a real-time clock/calendar and 31 bytes of static RAM. It communicates with a microprocessor via a simple serial interface. The real-time clock/calendar provides seconds, minutes, hours, day, date, month, and year information. Only three wires are required to communicate with the clock/RAM: CE, I/O (data line), and SCLK (serial clock). Data can be transferred to and from the clock/RAM 1 byte at a time or in a burst of up to 31 bytes. The DS1302 is designed to operate on very low power and retain data and clock information on less than 1μW. The DS1302 has dual power pins, one for primary and another for backup. -

The BMP180 Breakout is a barometric pressure sensor with an I2C (“Wire”) interface. Barometric pressure sensors measure the absolute pressure of the air around them. This pressure varies with both the weather and altitude. Depending on how you interpret the data, you can monitor changes in the weather, measure altitude, or any other tasks that require an accurate pressure reading. -

The LilyPad Arduino consists of an ATmega328 with the Arduino bootloader and a minimum number of external components to keep it as small (and as simple) as possible. This board will run from 2V to 5V and offers large pin-out holes that make it easy to sew and connect. Each of these pins, with the exception of ( ) and (-), can control an attached input or output device (like a light, motor, or switch). -
FEATURES: - With voltage meter display,voltage meter error of±0.1V, the range of 0~40V. (note: to ensure that the voltage meter accuracy, please make sure that the input voltage is 4.2V or more). - Low light touch button switch measurement input or output voltage,and a light show is voltage measurement which road, and keep the last set, even if the power switch on again. - Voltmeter fine-tuning: hold down the button about 1-2s into fine-tuning mode, can remove button on the calibration at this time. (please do not use standby function, usually). - Low voltage meter can be closed,long press button closure voltmeter (minimum power loss). - Input voltage:4.2~40v(input voltage must be higher than to the output voltage of more than 1v). - Output voltage adjustable range1.25V~37V adjustable (input voltage must be higher than to the output voltage is more than 1V). -
