Para sa mga guro at paaralanFor teachers, schools and supporters
Isang libreng kurso: 13 aralin, mula sa isang LED hanggang sa robot na lumalaban. A free course: 13 lessons, from one LED to a fighting robot. Electronics and programming, taught in Tagalog with the technical vocabulary in English, run by a former aircraft avionics engineer at no charge. It ends in a tournament the whole school can watch.
Ang hagdan ng kurikulumThe curriculum ladder
Each lesson introduces exactly one idea and may lean on everything before it. Lessons 1–9 are shared with the drone continuation; the course splits at lesson 10.
| # | Aralin / Lesson | Introduces |
|---|---|---|
| 1 | Ang circuit ay isang bilogThe loop | A circuit is a loop; break it anywhere and everything stops. Breadboard, LED, one resistor. |
| 2 | Gaano karaming kuryente?Ohm's law | Current limiting. Predict → test → destroy: 1 kΩ dim, 220 Ω bright, 10 Ω dead. |
| 3 | Ang switchSwitches | Breaking the loop on purpose. Why a 4-leg button is really 2 pairs. |
| 4 | Isang direksyon langDiodes | Polarity; current flows one way only. The LED is a diode too. |
| 5 | Unang codeFirst code | ESP32 + Arduino IDE. A microcontroller is a switch you can program. |
| 6 | Mga loop at listahanCode that counts | Variables, loops, arrays, the serial monitor. Stop copying, start programming. |
| 7 | Pakikinig sa pindutanReading the world | Digital input and pull-ups; why a floating pin lies. |
| 8 | Switch na walang kamayMOSFETs | Switching more current than a pin can carry. The gate. |
| 9 | Dalawang paraan para pabagalin ang motorMotors and PWM | PWM; why burning voltage as heat is the wrong way. The flyback diode becomes essential. |
| 10 | PabalikH-bridge | Bidirectional control with a DRV8833. Four switches, two diagonal pairs. |
| 11 | Kontrol na walang wireWireless control | Bluetooth gamepad pairing, and a failsafe for when the link drops. |
| 12 | Idisenyo ang sarili mong botCAD and printing | A parametric chassis each pupil customises. Design is a parameter you change. |
| 13 | Ang labanThe fight | The tournament. Iteration after breakage — the hook, delivered. |
After 13, pupils who want to continue go on to a quadcopter: orientation sensing (IMU), closed-loop control, four-motor mixing, soldering and PCB design. That continuation is mapped but not yet built; it is deliberately a second finish line, not a requirement.
KagamitanEquipment
All of it is supplied by the club. Nothing is asked of the school beyond the room.
Bawat mesaPer bench (2–3 pupils share one)
- Breadboard and jumper wires
- LEDs, resistors (10 Ω, 220 Ω, 1 kΩ), push buttons
- 1N4007 diodes; a potentiometer with a knob
- ESP32 microcontroller and USB cable
- MOSFET, DRV8833 motor driver, two small DC motors
- Battery pack (low voltage, toy-safe)
Para sa buong klaseShared by the class
- A TV or projector showing the interactive graphic
- One laptop for the Arduino IDE

Paano ito tumutugma sa STEMHow it maps to STEM
ScienceAgham
Circuits, current, Ohm's law, polarity, heat as wasted energy, switching. Every claim is tested on the bench, usually by breaking something.
TechnologyTeknolohiya
Programming a real microcontroller: variables, loops, inputs, outputs, PWM, Bluetooth. Not block code — the same Arduino C++ used in industry.
EngineeringInhinyeriya
Design → build → test → fix. Parametric CAD, 3D printing, failure analysis after every fight.
Maths — 12+ extensionMatematika
V = IR, duty cycle, percentages and ratios, read off real meters. A boxed extension for older pupils; the core work is predict-test-observe and runs at any age.
At EnglishAnd English
Instructions and explanations are in Tagalog. Technical part names stay in English — resistor, MOSFET, breadboard, PWM — because that is what is printed on the part, what a datasheet says, and what pupils will meet in any further study. Every label on screen shows Tagalog first and English beneath it, seen repeatedly next to the object in the pupil's hand. That is comprehensible input: vocabulary attached to something already understood, which holds far better than a word list.
We are careful not to oversell this. The course builds technical vocabulary and reading exposure. It does not teach grammar or conversation, and we would rather say so than invite that comparison.
Paano tumatakbo ang klaseHow a session runs
- The interactive graphic runs on the TV; pupils walk up and operate it. Live breadboards on the benches show the same circuit with the parts in the same places.
- Small groups per breadboard. Older pupils are paired with younger ones — the one who explains learns the most.
- Printable worksheets go home with each pupil. The lessons also work on any phone, with no account.
- Session length and the number of sessions are being measured with a pilot group first. Expect the early lessons to take longer than the plan says; that is normal and we will not rush them.
Ano ang hinihingi naminWhat we ask of a school
A room, a table, and a TV or a wall to project on. That is the whole list. We bring everything else, we charge nothing, and the pupils keep what they learn.
