Ask a parent, teacher, or trusted adult before building, powering a circuit, using tools or batteries, or buying parts. Purchases are optional and at your own cost. If anything gets hot, smells burnt, leaks, swells, sparks, or moves unexpectedly, switch off or disconnect power without touching the damaged or hot part, then tell an adult. Read safety rules
