This module will provide students with the knowledge and skills required to specify and manage classroom based projects using analogue and digital electronic devices and equipment available in schools. Through the module activities students will develop the knowledge, skills, values and attitudes appropriate to the teaching of technologies. Building on the previous knowledge from ET4003 students will further develop an understanding of the necessity to develop internal and external visualisation capabilities to represent complex information relating to electrical circuits and systems. The module engages students in a broad range of activities such as free-hand sketches, analogies, metaphors, visual circuit simulation software and physical models of circuits to support the development of conceptual understanding. These representations also support students in communicating design elements during their project outcomes.

Review of fundamental electrical properties (voltage, current, resistance, power), resistor and capacitor networks (equivalent series and parallel networks, voltage divider, charging and discharging of a capacitor, time constant). Electromechanical relays and sensors such as micro-switch, proximity sensors (inductive, capacitive, ultrasonic), thermistors and light-dependent resistors (LDR). Diodes, LEDs and rectifiers (half-wave and full-wave). Unipolar (MOSFET) and Bipolar Junction Transistors (BJT). BJT switch and amplifier circuits with sensors and output devices - lamp, buzzer, LED, speaker, motor, relay. Operational amplifier (OpAmp) circuits e.g. inverting OpAmp, non-inverting OpAmp, differential OpAmp, summator, integrator, differentiator, buffer, comparator and Schmitt trigger. Timer 555 and multivibrators circuits (astable, monostable and bistable) e.g. oscillators and de-bouncers. Logic gates: AND, OR, NOT, NAND, NOR and XOR - described using truth tables. The main logic families (TTL and CMOS). The use of logic gates with sensors and output devices. Logic gate circuits such as SR latch, flip-flops (JK flip-flop, D flip-flop, T flip-flop), counters, and seven segment displays drivers. Programming of microcontrollers such as Arduino Uno to control output devices and react to input signals from sensors. Strategies for teaching this subject area at second level. Create awareness of the application of graphical communication systems in the electronics discipline/industry with specific emphasis on how graphical representation facilitates the iterative design evolution and communication of electronics based systems. Designing, planning and managing appropriate teaching and learning activities for this subject area.

On successful completion of this module, students will be able to 1. Demonstrate an understanding of the operation of circuits that they design and troubleshoot these circuits. 2. Select the appropriate type (CMOS or TTL) of IC for a particular task 3. Learn to use a microcontroller for the development and testing of an electronic device. 4. Select and justify appropriate media or techniques to graphically communicate or model electrical circuits/systems.

On successful completion of this module, students will be able to: 1. Demonstrate an awareness of, and value of graphical communication in aiding the iterative nature of problem solving during the design and creation of electronic circuits and systems.

On successful completion of this module, students will be able to: 1. Design, test and modify circuits incorporating the use of transistor switches and op-amps 2. Construct and assemble a number of projects that incorporate output devices - motors, sirens, alarms, etc Design, assemble, test and modify operational amplifier circuits for signal amplification, level detection and voltage comparison. 3. Construct truth tables for up to four inputs using an array of up to four logic gates 4. Design, construct, test and modify simple systems using sensors, combinations of gates and output devices, buffer or driver circuits for a variety of output devices, and simple counting circuits capable of counting inputs from switches or clocks. 5. Model a circuit containing the components, inputs and outputs described above using appropriate software (e.g. Control Studio /Livewire/Crocodile Clips) and generate the relevant graphical outputs of circuit diagrams and PCB layouts.

This module is delivered through both lectures and laboratory based activities. Lectures will provide students with the prerequisite knowledge on the principles underpinning laboratory related activities. Project and problem-based learning will be embraced to create a constructivist learning environment for students with group work being utilized to encourage dialogue and communication throughout the applied learning and assessment tasks. In the module students will use multiple modes of representation (written report, sketching, graphical and physical models, simulations, diagrams etc.) to develop and communicate their design concepts and outcomes in their project-based learning activities.
