For Christmas we got our son an Arduino Uno starter kit. It’s not officially and Arduino, though. The hardware specifications are the same, but it is made by a company called Elegoo. What we purchased was the “Complete Starter Kit”. I highly recommend it. So far we’ve made prototypes for the following: 1) blinking LED lights, 2) joystick controlling a servo motor, and 3) an ultrasonic sensor that tells us how far objects are from it. There have been a few other things, but those are what come to mind as I write.
Besides being extremely fun an interesting, these prototypes foster a new understanding about all the electronic things we use and how they may be wired. We could have gotten a kit for a robot or a remote controlled car, but testing out a range of sensors seems to broaden our view of what’s possible. If we decide on a full project, we’ll have a much better idea of what we’ll need and whether it will work.
Also, as a side note, since I’m using my Chromebook for these project I’m not using a locally installed IDE. Instead, I’m paying $1 a month to use the cloud service provided by Arduino for building sketches. So far it has worked flawlessly. Though ChromeOS does have a linux sandbox now. I’m going to see if I can install it that way, too.
