Earlier today, Josh (a fellow intern and blog contributor) wrote a blog post about logic gates. After reading through Josh’s post and gaining an understanding of the concepts and basic functions of those gates, I figured now would be the perfect time to learn some code. I am going to go over each logic gate and it’s code in Verilog (a hardware language), VHDL (another hardware language) and C (software language).

Take a look at a circuit board and chances are you’re going to find a resistor or two. Most boards today use surface-mount device (SMD) technology, so the components are almost too small to see sometimes, but they are on there, I promise. How do engineers decide which resistors to use in the design? Sometimes it depends on how you want that portion of the circuit to perform, as in the case of an op-amp. Other times it’s to prevent too much current from passing through a given point in a circuit, which is why they are often called current-limiting resistors. Maybe you want a simple way to divide the voltage or current. The reality is that there are numerous ways to use resistors, and oftentimes, the defining the resistor value is up to you.

There are motors everywhere in the world around us– in cars, printers, computers, washing machines, electric razors, you name it. Unfortunately, there are a lot of people (myself included up until very recently) that wouldn’t know what to do if they were handed a motor and told to run it. So I decided that I want to change that. Let’s learn to run a stepper motor!
