Arduino and Tinkercad Foundations: Microcontrollers and Circuit Simulation

Getting started with physical computing and hardware does not require expensive components or specialized workspace. This course guides you through the fundamental principles of electronics and microcontroller programming using browser-based circuit simulation. You will learn how basic components function together and how to write clear code to control hardware logic step by step. What you will learn: Understand essential electronics terminology, circuit design principles, and component behavior; Design and test virtual electronic circuits inside Tinkercad; Write basic C/C++ scripts to handle digital inputs, outputs, and sensor signals; Apply pulse-width modulation for precise LED and motor control; Troubleshoot common logic and wiring mistakes in a simulated environment. The course starts with foundational definitions and elementary circuit concepts before introducing code structures and practical written exercises. This course is ideal for complete beginners and students with no prior background in programming or hardware design. Read through the lessons and start building your virtual projects today.
