Calculating Power

Introduction to Calculating Power (Watts) If you are not familiar with calculating resistance or current, please visit these posts.   This will help you better understand basic electrical principals before trying to calculate power. The Unit of power is the WATT.    Power itself is easy to calculate, but we Read More »

Calculating Current

Introduction to Calculating Current (Amps) In the last post, we discussed how to calculate resistance.   If you are unfamiliar with calculating resistance, please review the post before continuing.  In this post, we will learn to calculate current. We talked about a variable resistance being similar to the water faucet Read More »

Calculating Resistance

Introduction to Calculating Resistance (Ohms) In this section, we will be calculating Resistance in series and parallel circuits.  A resistor is one of the most basic components of electrical circuits.  The unit of resistance is called an Ohm.   It’s purpose is to restrict the flow of electrons.  To relate this to Read More »

Hall Effect Sensor 2

Introduction to the Hall Effect Sensor A hall effect switch is a component that provides an output based on the strength of a magnetic field.   This can be used for many applications, such as a simple alarm on a door or window. More complex applications would include the speed or direction Read More »

Getting Started with Microprocessors

Introduction to Arduino (Microprocessor Introduction) This document will give you a Microprocessor Introduction to the Arduino Uno.  There are other variants of this board, such as the Mini, Nano, Yun, Leonardo, and Esplora.    In addition, there are many off brand products such as Einsboard and Funduino.   Although the Read More »


What is a Transistor?

Introduction In short, a transistor is a switch.    This is much like the switch you use to turn on the lights in your home, but with a lower DC voltage, and a smaller amount of current (amps).    Instead of the switch being physically moved to turn a load Read More »

ZS-042 Real Time Clock 5

Introduction I purchased the ZS-042 on Ebay (advertised as DS3231 AT24C32 IIC) as a replacement for my DS1302 RTC modules. The DS1302 seemed to work very well for my application, but it lacked accuracy. Over a period of about 4 months, the DS1302 gained about 8 minutes.   The ZS-042 seems Read More »
