The Theremin was the first music synthesizer. The Junior Theremin is our, smaller, version of that classic electronic musical instrument. As you move your hand towards and away from the wire aerial, the Theremin responds by changing the pitch of the note it is playing. It can play individual notes as well as varying the tone of a single note.
How do you use the theremin?
The wire aerial responds to the movement of your hand towards and away from it and changes the pitch of the note it plays, without actually being touched. Junior Theremin works in two modes – continuous and discrete. When you first connect the battery Junior Theremin is in continuous mode. Pressing both pushbuttons together switches between continuous and discrete modes. Discrete mode, as its name implies, plays individual or discrete notes rather than a continuously variable tone. Eight notes over a single octave are available. In discrete mode the two pushbuttons change the octave of the notes. The left-hand pushbutton (marked -) lowers the octave, and the right-hand pushbutton (marked +) raises the octave. The pushbuttons only change the octave so long as they are pressed. In continuous mode the pushbuttons have no effect.

Analogue Electronics and Microcontrollers Projects
Hobbyist electronics can be a fun way to learn new skills that can be helpful to your career. Those who understand the basics of electronics can design their own circuits and projects. However, before you run, you need to learn to walk.
It all starts with analogue electronics. You should be familiar with the simple components and circuits and understand their basic behaviors and the issues you may encounter. The best way to do this is through real experiments. Theory alone is not enough. This book offers a large number of practical entry-level circuits, with which everyone can gain the basic experience.
Through the widespread introduction of microcontrollers, a new chapter in electronics has begun. Microcontrollers are now performing more and more tasks that were originally solved using discrete components and conventional ICs. Starting out has become easier and easier thanks to platforms including Bascom, Arduino, micro:bit. The book introduces numerous manageable microcontroller applications. It?s now a case of less soldering and more programming.
Get started with microcontroller based electronics
This Arduino-compatible bundle contains the Motherboard, Digitiser, Sensor Array and RGB Matrix. With these 4 boards you have everything you need to build a clock, score counter, timer, task reminder, thermometer, humidity display, sound meter, light meter, clap trigger, colored bar graph display, animated alarm, and much more!
The Motherboard has a built in real time clock module that keeps time even when unplugged.
The Digitiser can display 4 digits or characters and includes 2 buttons and a potentiometer to let you control what’s being displayed, or the brightness of the display.
The Sensor Array can read temperature, relative humidity, sound and light, with an SD card slot for data recording.
The RGB Matrix has 16 RGB LEDs that are controlled through shift registers, so only use 3 or 4 pins of the Motherboard.
Motherboard
The Motherboard is an Arduino-compatible microcontroller breakout board designed around the ATmega328P. The board comes in a solder-it-yourself kit with all the components you need to get started with microcontroller based electronics. All other boards connect to this.

On-Board RTC (Real Time Clock)
FTDI Header for easy programming
Bluetooth Header
Terminal Block Connections
Digitiser
The Digitiser is a versatile display and input board. It let’s you visualise your data. Show your sensor information, clock digits, or even keep score for your favourite card game. The Digitiser also includes some buttons and a knob to let you take control.
4x 7-Segment Displays
Uses 595 Shift Registers
2 Switches and a Potentiometer
4 colored 'Mode' LEDs
Chainable with other 595 Boards
Terminal Block Connections
Sensor Array
As the name suggests, the Sensor Array is an array of sensors. Measure temperature and relative humidity via the DHT11, light via the light dependant resistor, and sound via the microphone and amplifier circuit. Then you can log the data using the on-board SD card slot.

Light Dependent Resistor
MicroSD Slot for Saving Data
Logic Level Converter Circuit
Terminal Block Connections
RGB Matrix
Add color to your project by controlling 16 red, 16 green and 16 blue LEDs with just 3 pins of your microcontroller. The RGB Matrix uses shift registers, a matrix and switching transistors, so there’s plenty to learn and explore.

This book is aimed at practising engineers, students and hobbyists. It is intended as a source of reference for hardware and software associated with instrumentation and control engineering. Examples are presented from a range of industries and applications.
Throughout the book, circuit diagrams and software listings are described, typical of many measurement and control applications. The hardware and software designs may be used as a basis for application by the reader.
The book contains examples of PIC, PLC, PAC and PC programming. All code samples are available to download free of charge from the support website.
After an introductory section on control theory and modelling, the text focus is upon software for control system simulation and implementation, with appropriate reference to interfacing, electronic hardware and computing platforms.
Introduction to Control Engineering is a sourcebook of solutions for control system applications!
