Video description
An introduction to electronics to help you make the most from your Arduino or other prototyping platform
About This Video
Learn more about electrical concepts and diodes
Calculate voltage, current and resistance
Make use of resistors, capacitors and transistor
In Detail
Are you an Arduino maker, able to make things by following how-to guides and are confident with writing or modifying sketches, yet you are not so confident about things like calculating transistor currents, voltage drops and using capacitors as filters?You are not alone. I have been teaching Arduino and Raspberry Pi topics for years. During this time I have realized that while these platforms are great for helping you to start tinkering with electronics, you will not be able to truly enjoy their power until you have understood basic electronics.This is what this course is about. It is about helping you achieve a better level of understanding of the basic electronics principles and components that are commonly used in making on platforms like the Arduino and the Raspberry Pi. I have designed this course for anyone with a basic understanding of electronics, who has already spent time tinkering with Arduinos. By the end of this course, you will have learned how to use commonly used components found in Arduino projects. You will also have learned how to do the relevant measurements and calculations to help you select appropriate components for your projects.
To complete this course, you will need a few cheap and common components and tools: resistors, capacitors, transistors, LED, diodes, and batteries. You will also need a multimeter, a small breadboard and jumper wires. All of these are probably things that you already have.
