This weekend, I got a little bit closer. I learnt how to hook up an LCD display to an Arduino system, how to...

This circuit instead brings in the concept of analog versus digital circuits, something that is worth explaining. In the digital realm, a signal is “on”...

There are enough parts that I am sure I can go well beyond the scripted projects. Last night, I did the (really minor) assembly, but didn’t dive in. However, this morning, I dove right in, and did the first project. As one would...
