Built by a student who actually wired these circuits — not a licensed teacher, not a generic PDF pack.

You get:
• Three microcontroller experiments (LED current, voltage divider, simple sensor) with photos of real breadboard wiring
• Printable data tables, hypothesis sheet, and a judge-ready display layout
• Debug flowchart for when the LED stays dark or the serial monitor is blank
• Parts list using cheap generic boards — no branded kits required

For grades 6–10, 2–6 weeks before a fair. Digital download plus member chat. Hardware is not included.
