Embedded Systems Essentials: Digital Output Devices and Analog Signals

Overview

This course covers the essentials of digital output devices. Different types of digital displays are examined before taking a closer look at seven-segment displays. Next up are analog signals, followed by an introduction to Ohm's Law, which will help you understand the relationship between voltage, current, and resistance.

Syllabus

Digital Output Devices

This lesson explores the wide range of digital output devices and play technologies, each designed for particular applications, from basic bar LEDs to dynamic, full-colour displays.

Seven-Segment Displays

Learn about the seven-segment displays' evolution and applications, covering common anode/cathode configurations and scanning techniques.

Analog Signals

In this lesson, you will learn analog signals in embedded systems, their conversion to digital via ADCs, the maths behind it and put that into practice through a sensor exercise.

Introduction to Ohm’s Law

The Ohm's Law is a fundamental subject in electronics. To lay the foundation, this lesson covers the concepts of voltage, current and resistance before explaining their relationship.
