Small, repeatable demos that prove capability and generate content fast.
Sensor dashboard (Temperature / Humidity)
One sensor + one microcontroller + a simple page showing live readings.
Beginner
Motion + light “security” demo
Motion sensor triggers a light or buzzer; log events to a simple counter.
Content-friendly
Power basics: USB vs 12V vs battery
Show safe powering options, common failures, and how to avoid brownouts.
Practical
Button → relay → real-world output
Press a button, switch a relay, control something low-risk (LED strip, small fan).
Control
Continuity + troubleshooting walkthrough
Teach the simplest debugging: power, ground, continuity, signal path.
Repair
3D printed enclosure + device build
A small device looks “real” once it’s enclosed. Pair with the 3D track.
