Mother’s Day was approaching, and I am getting my 8 year old son started with electronics. So why not combine the two? In the next few pages we’ll show you the project we did – a blinking heart with several effects, all driven by a microcontroller. Taught my son not only about how to make mommy happy (she LOVED the present), but also about project planning, prototyping, soldering, programming, and testing. Everything a budding little engineer needs!
As this was a learning project for my son, I wanted to keep everything as simple as possible. We started out breadboarding some fundamental circuits – hooking up the microcontroller, blinking a single LED, and so on. Then we decided about the layout of the LEDs and went scavenging for the necessary components in my lab in our basement.
