In this post we will go back to basics and look at using pushbuttons. This is the first device covered in my book Making Sense of 37 Sensors. A pushbutton or other switch is the simplest input device you can have in your microcontroller project, but it does have some pitfalls. Let’s look at a …
OK, it’s done and available on Amazon. This book covers the 37 Sensor Kits, at least most of the sensors available. 54 in all, although the count depends on whether variations of the same sensor count or not. While it doesn’t go “Far Inside” it does show how they can be used and provides better …
I just realized that I haven’t made a blog entry in a month. I’m just completing the next book on Arduino sensors. Kindle ebook and printed book, same contents, of course. The ebook is actually ready, but I’m taking a second round trip on the printed book, making it a bit easier to read. Expect …
While testing out the 37 sensor kits, I’ve got three of them with different sensors, I have discovered some design shortcomings which might end up in destroying either the sensor or the attached microcontroller (the Arduino board). The issues are with some of the sensors that aren’t sensors in the traditional sense. These are output …
I’ve gotten so intrigued by my “37 sensor” kit that I’ve purchased two more different ones. Lots of commonality, quite a few of the 37 that don’t match the definition of a “sensor”. So I don’t know how many real sensors I’ve got! Because of the poor to no documentation provided and all bad reviews …
I recently got enthused to check out all of the sensors in my Elegoo 37 Sensor Kit (version 1) I bought 5 years ago. I suppose I should have checked them all out at the time because seven of the sensors, the ones on the red circuit boards, didn’t function at all. I’ve heard that …
