This module will introduce you to the broad spectrum of activities comprising electronic engineering and the analytical methods needed to support it. It is designed to give continuity into Electronics: signal processing, control and communications (T312). The combined modules will strongly emphasise the development of the practical knowledge and skills required by industry.
It’s presented in five blocks. The first block introduces the module and shows how sensors, logic and actuation are combined to make working systems. The context of the overall module is the sensing–logic–actuation cycle, in which electronic systems (i) collect information about their environment through sensors responding to light, sound and other physical phenomena, (ii) use logic and signal processing to reason about the sensor data in the context of what they already know, to plan and decide what to do next, and (iii) control their motors and actuators such as wheels, legs, arms, and grippers to move and operate successfully within their environment. The theory will be illustrated by many electronic systems, from the devices everywhere in our homes and everyday lives to state-of-the-art systems across various application areas.
Block 1: Introduction
This block introduces and motivates the module, explaining the roles of sensing, logic and actuation in electronics engineering. Building on the basic theory of electricity, you’ll learn about common electronic devices and how they work together to make circuits with standard functionality. You’ll learn how to read and draw schematic diagrams for electronic systems. This is supported by circuit design and simulation software. You’ll be introduced to the OpenEngineering Laboratory and experiment on a driven pendulum that produces sine wave signals similar to those in electrical and electronic systems.
Block 2: Sensing
You’ll learn about sensors, signals and signal processing. You’ll learn how various sensors work, including light-dependent resistors, photodiodes, thermistors, pressure sensors, and ranging devices, and how to design robust sensor circuits using operational amplifiers (op-amps). The theory of Fourier analysis is developed and used as the basis of signal processing, including sampling and filtering. You’ll use your computer to investigate various aspects of signal processing and filtering out noise. Circuit simulation software and OpenEngineering Laboratory experiments will give you experience in sensor circuit design and signal processing using industry-standard interfaces controlling real devices. The OpenEngineering Laboratory experiments include photodiodes and strain gauges.
Block 3: Logic
This block covers the basics of Boolean logic and the use of binary numbers and sequential logic in computing devices and controlling systems. You’ll learn about microcontrollers and microprocessors, including how they can be programmed to read sensors and control actuators. In your OpenEngineering Laboratory experiments, you’ll use a specially designed digital logic tutor board, with real digital logic gates, that can be rewired instantly from your computer.
Block 4: Actuation
This block covers actuators and the circuits that drive them. You’ll learn about transistors and semiconductors, electromagnetics, linear actuators, DC and stepper motors, cooling in electronics, and control. You’ll use the OpenEngineering Laboratory and circuit simulation software extensively. The OpenEngineering Laboratory exercises will involve controlling various motors and measuring their properties.
Block 5: Integration
This block illustrates the process of designing electronic and mechanical systems using a quadcopter drone case study. You’ll learn that the integration process iterates between the whole system's design and its interacting subsystems' design. The OpenEngineering Laboratory exercise experiments with ranging devices.

There may be extra costs on top of the tuition fee, such as set books, a computer and internet access.
If your income is not more than £25,000 or you receive a qualifying benefit, you might be eligible for help with some of these costs after your module has started.
There may be extra costs on top of the tuition fee, such as set books, a computer and internet access.
If your personal income is £25,000 or less, or you’re on certain benefits, you could qualify for a grant and OU top-up funding to cover 100% of your course fees. Apply online at the same time as you register on your module.

The Open University Student Budget Accounts Ltd (OUSBA) offers a convenient 'pay as you go' option to pay your OU fees, which is a secure, quick and easy way to pay. Please note that The Open University works exclusively with OUSBA and is not able to offer you credit facilities from any other provider. All credit is subject to status and proof that you can afford the repayments.
You pay the OU through OUSBA in one of the following ways:
Joint loan applications
If you feel you would be unable to obtain an OUSBA loan on your own due to credit history or affordability issues, OUSBA offers the option to apply for a joint loan application with a third party. For example, your husband, wife, partner, parent, sibling or friend. In such cases, OUSBA will be required to carry out additional affordability checks separately and/or collectively for both joint applicants who will be jointly and severally liable for loan repayments.
As additional affordability checks are required when processing joint loan applications, unfortunately, an instant decision cannot be given. On average, the processing time for a joint loan application is five working days from receipt of the required documentation.
