Resistor Color Code Quiz

Learn to read resistor color codes - whether you're a beginner tinkering with Arduino or an experienced engineer. The app generates random resistors with 3, 4 or 5 colour bands from the E6 to E192 series and asks you to pick the right value from four options. Daily rounds with streak tracking, bronze-silver-gold medals and a built-in colour code reference turn practice into a habit.

• E6 to E192 - resistors with 3, 4 or 5 colour bands
• Multiple choice with 4 options, one correct answer
• Daily rounds with streak tracking
• Bronze, silver, gold medals based on daily performance
• New question type: identify the digit value of a single colour band
• Detailed feedback and score tracking
• Built-in colour code reference explaining how values are calculated
