I am the noobiest noob ever and need some guidance. I only started electronics a few days ago, and I am currently building an auto doser for my aquarium. I thought this would be easier than building a full on aquarium controller. I also though this would be a good place to start learning as well.
I have an Arduino Uno with a DFRobot LCD Keypad Shield (16,x2). I am using the available digital pins for a 4 channel relay board and was told that I could connect my DS3234 RTC to the analog pins on the LCD shield. Is this true, and if so, how exactly? I imagine (from shield to RTC) GND to GND, 5V to VCC, but which pins do I assign to CLK, MISO, MOSI, SS, etc.?
Furthermore, which pins do I then declare in my code as INPUTS? Is there a specific code available for this method of connection?
So far I've gotten the code to do more or less what I wanted, but I just need to include the code for the RTC. Any help would be greatly appreciated.
Hi Brian83, welcome to the great world of electronics and programming.
To do things the way it should be done, start doing the examples that you got when installing the IDE.
You'll learn how to get a LED to blink, and you can practice you understood what's going on by having it blink in another pattern, or add a LED (and later a few), and have them do different things.
That will keep you busy over the rest of this weekend.
Take it step by step, and don't try to do a meaningful project within the first week of starting with your Arduino, electronics and programming.
You're far from even starting with your aquarium gizmo, but you might be getting close at Christmas time this year.
Meanwhile, instead of staring to your screen, waiting for a very long entire day for some replies, you already found this warning about your LCDkeypadShield, right ?
And for sure you used the search function to find 5 pages of links to DS3234 related topics.
In the Arduino Uno page, you found the schematics of it, revealing that pins 10, 11, 12, 13 are the same as SS, MOSI, MISO, and SCK on the ICSP header, right ?
No wonder you didn't get any reply here.
You already found about all you asked for yourself in these 24 hours.
Is there something else you really don't need help with ?
