The advent of electronics has had a profound impact on our lives and impacted nearly every product that we use either directly or indirectly. Without electronics, present day computers, cell phones, stereos, televisions, and the internet would not be possible. And of course, without computers and modern communications tools, society could not have made the huge strides in fields such as medicine, aerospace technologies, meteorology, transportation, agriculture, education, and many others. It is for these reasons that the invention of the transistor is considered as one of the most important technological advancements in history.

During this lesson student will learn the basics of electronics to help prepare them for the Electronics Design Brief.

This set of 10 lectures (about 11+ hours in duration) was excerpted from a three-day course developed at MIT Lincoln Laboratory to provide an understanding of radar systems concepts and technologies to military officers and DoD civilians involved in radar systems development, acquisition, and related fields. That three-day program consists of a mixture of lectures, demonstrations, laboratory sessions, and tours.

In this activity, learners use a laser pointer and two small rotating mirrors to create a variety of fascinating patterns, which can be easily and dramatically projected on a wall or screen. In this version of the activity, learners use binder clips to build the base of the device. Educators can use a pre-assembled device for demonstration purposes or engage learners in the building process.

This resource consists of 8 lecture PPTs, for the Course _Mechatronics. It covers, Sensors, PLC I/O modules, Hydraulic & Pneumatic systems, Maintenance of the System, Safety & Hazards.

Students are challenged to design and program Arduino-controlled robots that behave like simple versions of the automated guided vehicles engineers design for real-world applications. Using Arduino microcontroller boards, infrared (IR) sensors, servomotors, attachable wheels and plastic containers (for the robot frame), they make "Lunch-Bots." Teams program the robots to meet the project constraints—to follow a line of reflective tape, make turns and stop at a designated spot to deliver a package, such as a sandwich or pizza slice. They read and interpret analog voltages from IR sensors, compare how infrared reflects differently off different materials, and write Arduino programs that use IR sensor inputs to control the servomotors. Through the process, students experience the entire engineering design process. Pre/post-quizzes and coding help documents are provided.

What is inside a video game controller? Students learn about simple circuits and switches as they build arcade controllers using a cardboard box and a MaKey MaKey—an electronic tool and toy that enables users to connect everyday objects to computer programs. Each group uses a joystick and two big push button arcade buttons to make the controller. They follow provided schematics to wire, test and use their controllers—exploring the functionality of the controllers by playing simple computer games like Tetris and Pac-Man. Many instructional photos, a cutting diagram and a wiring schematic are included.

This course models multi-domain engineering systems at a level of detail suitable for design and control system implementation. Topics include network representation, state-space models; multi-port energy storage and dissipation, Legendre transforms; nonlinear mechanics, transformation theory, Lagrangian and Hamiltonian forms; and control-relevant properties. Application examples may include electro-mechanical transducers, mechanisms, electronics, fluid and thermal systems, compressible flow, chemical processes, diffusion, and wave transmission.

A collection of instructional modules complete with assignments, intended for an "inverted" classroom format, on the subject of electricity and industrial electronics.

A technician is only as accurate as the measurement equipment they are using. If the equipment is used incorrectly or is faulty, then the measurements will be inaccurate. If the measurements are inaccurate, then the technician will draw the wrong conclusions. To avoid getting inaccurate readings, you need to handle, use, and store meters properly. When you are done using a multimeter, it should always be turned off to extend battery life.

In this activity, learners construct a device out of a piezoelectric igniter, like those used as barbecue lighters. Learners use the device to remotely start current flowing in a simple series circuit containing a small electric fan.

"New technologies for enhancing electronics and photonics are crucial for emerging applications in energy, sensing, artificial intelligence, and countless other areas. But these technologies are hard to come by using traditional semiconductors. Over the past decade, so-called third-generation semiconductors have proved to be a boon to materials science and engineering, giving researchers increased versatility in boosting device performance. Among the most promising properties of these materials is piezoelectricity—the ability to convert mechanical energy to electrical energy and vice versa. The December 2018 issue of the MRS Bulletin takes a look at how researchers are exploiting piezoelectricity in semiconductors to enhance electronic and photonic devices like never before, providing a glimpse into the world of piezotronics and piezo-phototronics. In 2006, Zhong Lin Wang’s group at Georgia Tech discovered that piezoelectricity in zinc oxide nanowires exerts a gating effect like that in transistors..."

You can build a wide range of practical electronic devices if you understand a few basic electronics concepts and follow some simple rules. These devices include light-activated and sound-activated toys and appliances, remote controls, timers and clocks, and motorized devices.
The subject begins with an overview of the fundamental concepts, followed by a series of laboratory exercises that demonstrate the basic rules, and a final project.

Students work as if they are electrical engineers to program a keyboard to play different audible tones depending on where a sensor is pressed. They construct the keyboard from a soft potentiometer, an Arduino capable board, and a small speaker. The soft potentiometer “keyboard” responds to the pressure of touch on its eight “keys” (C, D, E, F, G, A, B, C) and feeds an input signal to the Arduino-capable board. Each group programs a board to take the input and send an output signal to the speaker to produce a tone that is dependent on the input signal—that is, which “key” is pressed. After the keyboard is working, students play "Twinkle, Twinkle, Little Star" and (if time allows) modify the code so that different keys or a different number of notes can be played.

In this activity, learners explore electronics and motion by making a Scribbling Machine, a motorized contraption that moves in unusual ways and leaves a mark to trace its path. It's made from simple materials and is based on the idea of motion created by an offset motor. Try using harvested motors and switches from discarded toys and electronics to make your Scribbling Machine - this not only keeps costs down, but is a playful and inventive way to explore how everyday objects work. To take the activity further, you can also incorporate PicoCrickets to make your Scribbling Machine more intelligent and to explore computers.
