What you'll learn:
- Understand the concepts of voltage, resistance and current
- Use Ohm's Law to calculate voltage, current and resistance
- Use Kirchhoff's Laws to calculate voltage and current
- Understand the meaning of and calculate energy and power
- Use resistors in various configurations, like in voltage dividers and voltage ladders
- Read the value of a resistor from its package
- Use pull-up and pull-down resistors
- Understand the use of capacitors
- Use capacitors as energy stores and filters
- Calculate the RC time constant of a capacitor
- Understand diodes
- Measure the voltage drop of a diode
- Understand how to use rectifier and zener diodes
- Protect a circuit from reverse polarity
- Understand how to use a transistor to control low and high power loads
- Calculate the currents and base resistor for a bipolar transistor
- Use the correct voltage regulator for any circuit
I have updated this course with new lectures to teach you how to use an online circuit simulator. With this simulator, you can boost your understanding and learning of electronics. You will be able to conduct many experiments to examine multiple circuit scenarios and easily plot currents, voltages, and power without hardware expense. You will learn to use multiple power sources and built-in and custom component models. You can even conduct experiments that would be too dangerous to do in real life.

Are you an Arduino maker? Can you 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 realized that while these platforms are great for helping you start tinkering with electronics, you will not be able to enjoy their power until you truly understand basic electronics.
This course is about helping you achieve a better understanding of the basic electronics principles and components commonly used in making platforms like Arduino and 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, LEDs, 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.
