Hardware & Software

You'll need some basic hardware components and tools for hands-on experiments to get the most out of this course. This includes a breadboard for prototyping circuits, a selection of common electronic components such as resistors, capacitors, diodes, transistors, and LEDs, and a multimeter for measuring voltage, current, and resistance. Additionally, jumper wires, a power supply or batteries, and a few integrated circuits will be used in various projects. If you want to simulate circuits before building them, access to a computer with circuit simulation software is recommended. These items are readily available and will allow you to follow along with the course's practical exercises.

For this course, you'll need access to circuit simulation software to experiment with and test circuits before building them physically. We recommend using CircuitLab, an intuitive online circuit simulator that allows you to design and analyze circuits directly in your browser. As a student of this course, you will receive an exclusive discount for CircuitLab.
