Hardware Engineering Practice Exercises
Work through more than 600 hands-on exercises built for hardware and electronics engineers. Each exercise focuses on a single concept, from biasing a transistor to sizing an inductor or reasoning about setup and hold time, and is graded by AI with a written model solution.
Concept-by-concept practice
Exercises span circuit analysis, op-amps and filters, semiconductor physics, CMOS and digital logic, FPGA and RTL fundamentals, power conversion, control loops, PCB and signal integrity, sensors, and test and measurement.
Numeric and conceptual grading
Calculation exercises are graded numerically with unit conversion and a tolerance band, so equivalent forms of the same answer are accepted. Conceptual exercises get a percentage score plus short, plain-language feedback explaining what was missing.
Difficulty that scales with you
Filter by difficulty and topic to build a study plan, starting with fundamentals and moving into the advanced problems that separate candidates in a hardware interview loop.
Frequently asked questions
- How many exercises are available?
- More than 600 hardware and electronics engineering exercises across all major topics.
- How are calculation exercises graded?
- Numerically, with SI unit conversion and a tolerance band, so 16 mA and 0.016 A both count as correct.
- Do I need a paid account?
- Free accounts get a preview exercise; a paid membership unlocks the full library.
