Arduino Day and the Fading LED
On Arduino Day we joined makers around the world for a day of block coding, blinking LEDs, and a fading light that turned out to be an illusion.

Catapults from Ice Cream Sticks
Ice cream sticks and rubber bands. Catapults that snapped, got fixed, and launched. Newton's laws, felt through the fingers instead of read off a page.

Giving the Dispenser a Body
The water dispensers worked. They just looked like a tangle of wires. This session was about the box, and about how a working thing still isn't finished until someone else can use it.

A Touchless Water Dispenser
Thirteen students built a touchless water dispenser from an IR sensor, a transistor and a DC pump. The first build in the programme that does something genuinely useful.

A Street Light That Knows It's Dark
An LDR, a transistor, an LED and a battery. No Arduino, no code. Just a circuit that knows when it's dark, and a new way of looking at the street lights we walk under every night.

Periscopes and Kaleidoscopes
No batteries, no code. Just cardboard, mirror tiles and one rule about light, which turned out to be enough to see around corners and make patterns that never repeat.

IR Sensors That Notice a Hand
An IR sensor, an LED and a buzzer. For the first time, the circuit stopped waiting for us and started reacting to the room.

Ohm's Law and a Traffic Light
At Skill Hub we met Ohm's law, built a traffic light out of three LEDs, and found out that rules in electronics aren't there to be memorised. They're there because things burn out.
