Welcome to C Programming Tutorial 7, Arrays in C Part 2!
C Tutorial 6 was an introduction to arrays in C.
This time, we’re going to go into a little bit more detail about arrays after a quick review.
Let’s do this!

When someone poses the question what is a transistor or how does a transistor work they can literally find tons of material that answers those questions and gives more detail than perhaps one would care for.
Indeed, many books exist on the subject of transistors, semiconductor physics, transistor characteristics, and their operation. They range from the beginner level to the engineering level and even on to cutting edge research and new breakthroughs in the design of transistors and semiconductors.
Because of this, the answers you will find to the questions above (and similar ones) range from the simplistic to the extremely complicated.

The first article in this series, Intro to Common Sensors You’ll Use in Your Projects introduces temperature sensors and some common mechanical sensors.
It also promises that the next article will cover acoustic sensors and optical sensors.
I like to keep my word, so that is exactly what we’re going to do in this post.
Let’s jump right in…

I recently got the chance to assemble and test a Keyestudio (that’s not a typo, the spelling is correct) robot kit. The name of the kit is the Keybot Coding Education Robot for Arduino STEM.
That’s a long name, but it suggests a few things. First, the robot is an educational tool which attempts to spark interest in STEM (science, technology, engineering, and math) subjects.
Second, the robot is for children and teens, as there is a movement to spark an interest in STEM subjects in grades 1 through 12.
The robot is definitely a great educational tool for children age 7 or 8 to kids in their early to mid-teens. It makes a great gift for the aspiring Maker, tinkerer, or engineer. And it’s affordable.

In the land of electronics, there are many different types of sensors.
If you start dabbling in electronics, it won’t be long before you end up needing/wanting to measure some sort of quantity like temperature, speed, light level, distance, sound, humidity etc.
This is especially true if you work with Arduino, RPi, PICs, or any sort of platform or microcontroller.
These days, there are many different electronic sensors to choose from. Given the pace at which technology advances and the myriad of sensors available, those new to electronics often find themselves confused about sensors and how to apply them.
What type of sensors do I need? How do I use this particular sensor?
The above are common questions hobbyists often ask themselves.

A while back I published a tutorial on the basics of logic gates. The tutorial talks about what logic gates are, truth tables, and active levels.
Then, the tutorial talks about the basic logic gates many of us are familiar with: NOT, AND, OR, NAND, NOR, XOR, and XNOR.
Because of limited space, the post did not cover Boolean algebra, DeMorgan’s theorems, combinational logic, etc. It also leaves out an important and practical part of digital design with gates – the electrical characteristics of logic gates.
This tutorial on logic gates will with leave the topics of Boolean algebra, DeMorgan, etc. for a future tutorial.
This time, we’re going to focus on the important and practical, yet often overlooked, electrical properties and characteristics of logic gates.
