An Introduction to Circuit Simulation LTspice, developed by Analog Devices, is a powerful, fast, and free SPICE simulator, schematic capture, and waveform viewer with a large database of components supported by SPICE models from all over the world. Drawing a schematic in LTspice is easy and fast. Thanks to its powerful graphing features, you can visualize the voltages and currents in a circuit, and also the power consumption of its components and much more. This book is about learning to design and simulate electronic circuits using LTspice. Among others, the following topics are treated: DC and AC circuits Signal diodes and Zener diodes Transistor circuits including oscillators Thyristor/SCR, diac, and triac circuits Operational amplifier circuits including oscillators The 555 timer IC Filters Voltage regulators Optocouplers Waveform generation Digital logic simulation including the 74HC family SPICE modeling LTspice is a powerful electronic circuit simulation tool with many features and possibilities. Covering them all in detail is not possible in a book of this size. Therefore, this book presents the most common topics like DC and AC circuit analysis, parameter sweeping, transfer functions, oscillators, graphing, etc. Although this book is an introduction to LTspice, it covers most topics of interest to people engaged in electronic circuit simulation. The book is aimed at electronic/electrical engineers, students, teachers, and hobbyists. Many tested simulation examples are given in the book. Readers do not need to have any computer programming skills, but it will help if they are familiar with basic electronic circuit design and operation principles. Readers who want to dive deeper can find many detailed tutorials, articles, videos, design files, and SPICE circuit models on the Internet. All the simulation examples used in the book are available as files at the webpage of this book. Readers can use these example circuits for learning or modify them for their own applications.

The SQ series of handsfree PCBite probes from Sensepeek are insulated, come with included color-coded cable holders and have a lower point of gravity making them even more stable compared with the original SP series of probes. All the loved features of handsfree measurement, exchangeable fine pitch spring tipped test needle and the minimalistic design is maintained to make traditional sized and handheld probes obsolete. Features All handsfree probes from Sensepeek makes instant measurements or long triggering sessions a breeze. No more soldering wires to connect your probe or complicated tools to setup, just positioning the probe needle on any test point or component in the signal path and release. Saves time and frustration during development, verification and repairs. The minimalist design and the spring-loaded test needle makes it possible to simultaneously measure on fine pitch components and nearby signals. Both length and weight of the SQ probes are perfectly balanced to be used with the included PCB holders and base plate which is a must for handsfree function. The probe holder comes with a powerful magnet in the base, as for all PCBite probes and holders which makes the probe easy to place and reposition. The SQ series of probes can be used handheld without the probe holder as they have an insulated grip but their full potential is used when measuring handsfree. One side of the included baseplate is matte and the other is mirror polished. The mirror polished surface makes it easy to see components on the circuit board underside. For added protection during measurement the included insulation cover can be mounted on one of the surfaces. Included 4x PCBite PCB holders 1x Set of yellow insulation washers for the PCB holders 1x Large Base plate (A4) 1x Insulation cover for the base plate (A4) 1x Micro fiber cloth 4x SQ10 probes and pin tipped test needles (black) 2x Banana to dupont test wires (red/black) 5x Dupont to dupont test wires 1x Set of cable holders (4 colors) 4x Extra test needles Downloads User guide (PCBite kit) User guide (SQ10 probes)

The Internet of Things (IoT) is a new concept in intelligent automation and intelligent monitoring using the Internet as the communications medium. The “Things” in IoT usually refer to devices that have unique identifiers and are connected to the Internet to exchange information with each other. Such devices usually have sensors and/or actuators that can be used to collect data about their environments and to monitor and control their environments. The collected data can be processed locally or it can be sent to centralized servers or to the cloud for remote storage and processing. For example, a small device at the size of a matchbox can be used to collect data about the temperature, relative humidity and the atmospheric pressure. This data can be sent and stored in the cloud. Anyone with a mobile device can then access and monitor this data at any time and from anywhere on Earth provided there is Internet connectivity. In addition, users can for example, adjust the central heating remotely using their mobile devices and accessing the cloud. This book is written for students, for practising engineers and for hobbyists who want to learn more about the building blocks of an IoT system and also learn how to setup an IoT system using these blocks. Chapter 1 is an introduction to the IoT systems. In Chapter 2, the basic concepts and possible IoT architectures are discussed. The important parts of any IoT system are the sensors and actuators and they are described briefly in Chapter 3. The devices in an IoT system usually communicate with each other and the important aspect of IoT communication is covered in Chapter 4. Chapter 5 proceeds with the features of some of the commonly used development kits. One of these, the Clicker 2 for PIC18FJ manufactured by mikroElektronika, can be used as a processor in IoT systems and its features are described in detail in Chapter 6. A popular microcontroller C language, mikroC Pro for PIC gets introduced in Chapter 7. Chapter 8 covers the use of a click board with the Clicker 2 for PIC18FJ development kit. Similarly, the use of a sensor click board is described as a project in Chapter 9, and an actuator board in Chapter 10. Chapters 11 and 12 cover Bluetooth and Wi-Fi technologies in microcontroller based systems, and the remaining chapters of the book demo the creation of a simple Wi-Fi based IoT system with cloud-based data storage. This book has been written with the assumption that the reader has taken a course on digital logic design and has been exposed to writing programs using at least one high-level programming language. Knowledge of the C programming language will be very useful. Also, familiarity with at least one member of the PIC series of microcontrollers (e.g. PIC16 or PIC18) will be an advantage. The knowledge of assembly language programming is not required because all the projects in the book are based on using the C language. If you are a total beginner in programming you can still access the e-book, but first you are advised to study introductory books on microcontrollers.
