Arduino light sensor and illumination example

Arduino Uno

I’ve been meaning to follow up my previous getting started with the Arduino microcontroller article for a while now. Quite a long while as it’s almost three years. The other reason for writing this now is that my first article has been visited quite a lot recently, so I wanted to add to my electronics section. At the end of my last article I asked for suggestions of what to build next but didn’t have any responses. I thought I’d make a variation on my light switch example and have the light turn on when it starts to get dark and proceed to get brighter the darker it became. As

Getting started with the Arduino microcontroller

Arduino Logo

This is my first article about the Arduino microcontroller development board and indeed my first article in my new Electronics category. I am fairly new to this but filled with excitement as I delve into another hobby and perhaps a second childhood (or maybe a fifth or sixth). I say that because I have always had a keen interest in both electronics and programming and the Arduino mixes both of these interests. As a child, having an Arduino, would have saved many an electronic device from being “upgraded” by my small hands. I like to know how things work and then attempt to improve it. From my early childhood and
