After I finished my last Real Time Clock project, I was relatively happy with the outcome, well, everything except for the accuracy; and what good is a clock without accuracy? I used the DS1302 which I’m sure is a pretty decent RTC(real time clock), if you pair it with a crystal that’s perfectly matched for

A few years ago, I was spending a considerable amount of time away from my apartment. Some of this time arose during the winter months, and I found myself wanting to reduce the heating costs of the apartment, and therefor the temperature while I was away. Because the unit is adjacent to a few others,

One of the first Arduino projects that I started off playing around with was a clock. The project went through various iterations, and served as a learning experience for me. The first few sets of code I ran did not use a RTC (real time clock). At first I didn’t notice, or was not too
