I was wondering if anyone has done the following project? Thought I'd see if there was anyone familiar with this project, as I'm not finding any help on instructables.
This is my first time using an Arduino board. I've managed to verify/upload the provided code to the nano. Unfortunately, I'm only receiving one green light active (middle top green). No other LED's are lighting up. When I have my laptop disconnected from the Arduino board, the green light is off. Is there a step I'm missing? Any recommendations would be helpful.
It is currently powered by a 5V 2A power supply. I got the power source from Amazon, and for some reason there is an LED on it that blinks when its connected to the nano and when its not its solid red. Not sure what that signifies. I think I might have a faulty power supply.
Nano also has the CR2032 battery hooked up. The only way to get the one green light powered is when I have the usb cable attached to the nano.
I also ran serial plotter and the time was changing. Think the code is alright.
Attached is a picture of the wiring. Not the cleanest setup.
You have gone too far. I prefer a Arduino Uno with a prototype shield and test everything one by one. Did you check if the soldering is okay and does not make a shortcut to other things ?
The solder did not flow very well for some wires. For example this one:
Can you give a link to the power supply ?
Do you use a normal battery in the RTC ? Then you have to disable the charging circuit and remove the diode:
The RTC module works, that is nice.
Then try the leds at pin 12 and 13. I assume that the "Blink" test already worked with pin 13.
Then try a single display.
Is it possible to remove wires from the Nano without damaging it ?
The best solder iron is a direct heating (the heating element is in the tip) and temperature controlled solder iron.
Something seems to be wrong with the power. Does your power supply not power the Nano board ?
It is normal to have a number of test-sketches when making a project.
