Connecting HW and SW

RTC(real time clock) The RTC is an i2c device, which means it uses 2 wires to to communicate. These two wires are used to set the time and retreive it. on the Arduino, the pins are 'fixed' to be Analog 4 and 5 for the built in i2c capability. This is a bit annoying since of course we want to have up to 6 analog inputs to read data and now we've lost two. There is a way to use other pins...howeve..

데이터 로거(data logger) 쉴드(shield) Original-link : https://learn.adafruit.com/adafruit-data-logger-shield/shield-overview Shield Overview LADY ADA The datalogger shield has a few things to make it an excellent way to track data Top Left - There's a real time clock (RTC) which has a chip, crystal, and backup battery for up to 7 years of timekeeping Middle Left - an on-board 3.3V regulator keeps the s..

온도 센서, TMP006, I2C 통신 (Temperature sensor, I2C Communication) 원본 출처 : https://learn.sparkfun.com/tutorials/tmp006-hookup-guide TMP006 Overview The TMP006 is a temperature sensor that can detect the temperature of an object without having to make direct contact with it. The sensor has a thermopile which absorbs infrared energy from the object. The thermopile is composed of several thermocouples i..
