Day 1: Basics of Electronics – What is Electricity, Electrons & Circuits ⚡🔌
Magi introduces the basics of electronics — why we need it, what an electron is, and how electricity flows through a circuit.
▶
Day 2: Circuits & Switches 🔌
Magi explains open vs. closed circuits, series vs. parallel circuits, and how a switch turns a device on or off.
▶
Day 3: Current, Voltage & Conductors ⚡
Magi breaks down electric current and voltage, and the difference between conductors and insulators.
▶
Day 4: The Salt Water Battery 🧂🔋
Magi builds a salt water battery to show how zinc and copper create a chemical push that moves electrons.
▶
Day 5: Resistors Explained 🛑⚡
Magi uses a "bumpy road" analogy to explain how resistors limit current and protect electronic components.
▶
Day 6: The Potentiometer – A Dimmer Switch for Electricity 🎛️
Magi explains how a potentiometer works like a dimmer switch, with real examples like light switches and joysticks.
▶
Day 7: What is a Motor? 🏎️
Magi explores how a motor turns electrical energy into motion, from toy cars to washing machines.
▶
Day 8: The Electromagnet Adventure 🧲⚡
Magi builds an electromagnet from a battery, wire, and copper coil, and explores how it's used in doorbells and cranes.
▶
Bonus: SmartGuard – A Real Safety Project 🚲🔔
Magi puts it all together to build SmartGuard, an ultrasonic sensor alert system that warns cyclists of obstacles behind them.
