Overview
This workshop helps students understand that not every power source is suitable for every project. They learn why an LED, OLED, servo, pump, and motor place different demands on a circuit.
The workshop avoids unsafe charging or mains work. It focuses on classroom-safe USB power, AA/AAA battery packs, power banks, protected Li-ion packs handled by instructors, and reading module specifications before connecting loads.
Learning Outcomes
- Compare common classroom power sources for voltage and current capacity
- Read basic current requirements from modules and components
- Recognize symptoms of brownout or overloaded power
- Choose safe power options for sensors, displays, and small actuators
What You Build
A simple current budget for a small Arduino project plus a tested low-voltage power setup.
Materials Provided
Arduino-compatible board, USB cable, USB power bank, AA battery pack, multimeter, LEDs, OLED or servo demo load, current budget worksheet.
How Schools Can Integrate It
This workshop is ideal before mobile robots, plant monitors, and wearable-style projects. It supports safe planning rather than trial-and-error wiring.
