This is an Example of how you can use the Arduino to monitor various environmental parameters And display them on a LCD screen. Note: I Added a Real Time Clock! To see the steps, added parts and Sketch I added new steps.
I wasn’t allowed to have any digital clock or watch until I could tell time on a ‘real’ one. Not sure how I feel about it now. I also remember being told I needed to learn to do math in my head because wouldn’t ‘always’ have a calculator with me too.
