Resistor Mixer - The Ultimate Resistor Combination Calculator

Can't find the exact resistor value for your project? Resistor Mixer is your smart companion that finds perfect resistor combinations by mixing series and parallel configurations to achieve any target resistance value.

🎯 INTELLIGENT COMBINATION ENGINE
Resistor Mixer goes beyond simple calculations. Our advanced algorithm analyzes thousands of possible series-parallel combinations and presents you with the best solutions, ranked by accuracy. Whether you need a precise value for an LED circuit or a voltage divider, we've got you covered.

⚡ KEY FEATURES:

📊 Visual Circuit Diagrams
See exactly how to wire your resistors with professional circuit diagrams. Each solution includes a clear visual representation showing series connections, parallel branches, and mixed configurations. No more confusion about how to connect your components!

🔢 Dual Input Modes
- Standard Values Mode: Access the complete E12 resistor series (1Ω to 10MΩ) - perfect when you have a well-stocked parts bin or need to order new components
- Custom Values Mode: Enter your available resistors (comma-separated) to find combinations from what you actually have on hand

🧮 Complex Mixed Combinations
Unlike basic calculators, Resistor Mixer handles sophisticated configurations:
- Simple series: R1 + R2 + R3
- Simple parallel: R1 || R2 || R3
- Mixed configurations: (R1 || R2) + R3
- Nested arrangements: R1 + (R2 || R3)
- Parallel-series: (R1 + R2) || R3
- And many more complex patterns!

📈 Smart Results Display
- Multiple solutions for each query (up to 15 best matches)
- Error percentage for each combination
- Complexity rating (number of resistors used)
- Color-coded accuracy indicators
- Sorted by precision (best matches first)

🎚️ Customizable Search
Adjust the maximum number of resistors (2-3) based on your needs and available space on your PCB or breadboard.

💡 PERFECT FOR:

👨‍🎓 Students & Educators
Learn circuit design principles hands-on. Understand how series and parallel resistors work together to create any desired resistance value. Perfect for electronics courses and lab work.

🔧 Electronics Hobbyists & Makers
Building Arduino projects? Raspberry Pi circuits? LED lighting? Robot controllers? Resistor Mixer helps you find the right resistor combination quickly, so you spend less time calculating and more time creating.

🛠️ Professional Engineers & Technicians
Speed up your prototyping and PCB design workflow. Quickly find substitutes when specific values are out of stock. Verify your resistor networks before assembly.

📱 Repair Technicians
Replace damaged resistors with available alternatives. Find equivalent values when exact replacements aren't available. Essential for vintage electronics repair where original components may be obsolete.

🚀 HOW IT WORKS:

Step 1: Enter Your Target
Type in the exact resistance value you need (e.g., 330Ω, 1.5kΩ, 2.2MΩ)

Step 2: Choose Your Source
Select "Standard Values" to search the complete E12 series, or choose "Custom Values" and enter your available resistors separated by commas (e.g., 100, 220, 470, 1000)

Step 3: Calculate
Tap "Calculate Combinations" and let our algorithm work its magic

Step 4: Review Solutions
Browse through multiple solutions, each showing:
- Achieved resistance value with unit (Ω, kΩ, MΩ)
- Error percentage (how close to your target)
- Configuration formula (e.g., "(220Ω || 470Ω) + 100Ω")
- Number of resistors required
- Visual circuit diagram

Step 5: Build Your Circuit
Follow the circuit diagram to wire your resistors exactly as shown. Connect resistors in series end-to-end, and parallel branches side
