How much resistance does that LED have? What's the value of that 4-band resistor you have on the table?
This Electronics Course makes it clear: lessons with photos of real components and a lab for quick calculations. Open it, read, and you're ready to build.
— WHAT YOU'LL LEARN —
Electronics from scratch, in Spanish, and step by step. Each module explains what the component is, what it's used for, and what it actually looks like. It's not an endless PDF: it's a mobile course, with progress tracking and the option to pick up where you left off.
You'll understand:
• Ohm's Law (voltage, current, and resistance)
• Resistors, color codes, and power ratings
• Diodes, LEDs, and Zener diodes
• Capacitors, inductors, and transistors
• Power supplies, instruments, and circuit boards
— LAB —
When the theory asks for a number, you don't guess: you calculate.
• Ohm's Law — you specify resistance, voltage, or current. Example: 12 V and 0.02 A → 600 Ω
• LED Resistor — you choose the color and power source. Example: 5 V + red LED → 150 Ω (and it won't burn out)
• Color Code — you read the bands. Example: brown, black, red = 1 kΩ
• Series and Parallel — two values, two results. Example: 1000 Ω + 1000 Ω → 2 kΩ / 500 Ω
• Voltage Divider — input, R1 and R2 → Vout
The lab is designed for the workbench: quick and straightforward.
