My last data logging sketch was missing one feature to make it complete. Since I use a DS1307 RTC which is not very accurate, it loses a couple of seconds a day, I wanted to sync the time with a timeserver. Thankfully some smart people on the Arduino site have already made a library and […]
Made a really big sketch today 🙂 I used an Arduino Uno, ethernet shield with sd slot, DS1307 RTC and 2 temperature sensors for this sketch. I used 2 different temperature sensors, one is a DHT22 sensor which can also sense the humidity and the other is a DS18B20 sensor. To get all this to […]
I’ve been breaking my head over this for the last hour. I want to use the DS1307 RTC module in a home automation project. To do certain time based things. So I thought lets try to rewrite the “blink without delay” example that comes with the Arduino IDE and use the data from the DS1307 […]
