This is absolutely fantastic. Im so glad YT suggested your channel. Watched several of your vids today, and all are great work, very well explained, and well done. Thank you for this series!!

Question .. IK the code in this vid is based off an existing library, and as such can be altered as needed, but, is it suitable as-is for low-power consumption implementations, such as when running off battery power? Im looking to diy a daily timer system that will run off 12v DC battery.

Also, by way of feedback, I absolutely loved when you explained the use of capacitor and diode in the dc motor vid of this series. I would love to see a vid or vids re how and when to use capacitors, diodes, and resistors and how to choose these components in their appropriate values (e.g. what should the uF or Oh be of the cap/resistor). This is more EE, I realize, but I havent seen this yet in anything close to a beginner level. Your presentation style might be perfect for this. Thanks again, sry for tldr

hi, my rtc not working for automated pet feeder. how do i solve issues?😢

ChatGPT told me it's possible to attach the VBat to arduino analog PIN to check battery and light up a red LED if the battery is dead. I'd like to do that to warn users. Is that possible ?

Does this run in millaseconds? I am thinking about making a very time sensitive project and need it to monitor up to1/100 seconds

where can you download the code I cant find it on the Website ?

Plz can you give me the code and diagram??
