How does Fido know current time?

Primary tabs

Topic Type: 
Question

Just curious, how does Fido know what time it is? Does it get this information from the attached cell phone? Or does it need to be programmed by the user?

The datalogging shield from Adafruit includes an integrated circuit that provides a Real-Time Clock (RTC). It gets the current time when you upload code. It will use the coin battery to maintain accurate time when the shield is not getting powered.

If you notice that the time isn't being kept properly, it may be the coin battery that doesn't have a decent contact. I had that problem because I didn't put a significant enough blob on the circuit board. Let me know if you are having any issues and I can help you troubleshoot!
