Hello to everyone. I have a project. I have a filter coffee machine. I want the coffee machine to work at 7 every morning. For this project, I have arduino uno, rtc, relay, nokia 5110 screen. but I don't know how to code. I will prepare the coffee machine at night. At 7 o'clock in the morning, the relay will active on the switch and start the machine. I'm waiting for your help.
I'm waiting for your help.
What help do you need?
Start by writing, or obtaining from the libraries you use, example sketches that only test the hardware. That way you can be sure it works, so when you write the actual sketch you can rule out hardware problems if it doesn't work.
Actually, seeing those example sketches will give you clues about how to code your project.
