This paper reports on a design‑test‑fix cycle carried out from March 2023 to February 2025, focusing on for grades 7‑9. The results inform both academic practice and national digital‑learning strategies. video+bokeb+anak+smp+tested+fixed

| Segment | Timestamp | Key Activities | |---------|-----------|----------------| | | 0:00‑0:45 | The host introduces “Bokeb”, a 13‑year‑old student from SMP 2 C, who is attempting to build a “traffic‑light” prototype for his school’s robotics fair. | | Project Overview | 0:46‑1:30 | Sketch of the circuit (Arduino Uno, three LEDs, 220 Ω resistors, breadboard). Expected behavior: sequential blinking (red → yellow → green). | | Problem Statement | 1:31‑2:10 | After uploading the sketch, none of the LEDs light up. Bokeb suspects a hardware fault. | | Testing Phase – Visual Inspection | 2:11‑3:00 | • Checks power LED on Arduino. • Verifies all components are placed in the correct rows/columns. • Spotlights a mis‑aligned jumper wire that leaves the red LED unconnected. | | Testing Phase – Multimeter Checks | 3:01‑4:15 | • Measures continuity from Arduino 5 V pin to each resistor. • Detects an open circuit on the red LED path (0 Ω → ∞ Ω). | | Testing Phase – Code Debug | 4:16‑5:00 | • Opens the Arduino IDE, uses the “Serial Monitor” to confirm the sketch runs (prints “loop start”). • Confirms the issue is purely electrical, not software‑related. | | Fix Implementation | 5:01‑6:45 | • Re‑inserts the jumper wire, ensuring proper contact. • Re‑places the red LED with correct polarity (long leg to +5 V). • Re‑uploads the sketch (no changes needed). | | Verification | 6:46‑7:20 | All three LEDs blink in the correct sequence; Bokeb celebrates the success. | | Reflection & Take‑aways | 7:21‑8:00 | Host and Bokeb discuss the importance of a systematic test‑fix loop, documenting errors, and learning from mistakes. | | Outro & Resources | 8:01‑8:32 | Links to a printable troubleshooting checklist, the full Arduino code, and a downloadable PDF of the lab report template. | By working together, we can promote a culture
