Organization…
»You Shall…«
- use the lab upstairs. Keep it tidy!
- use the materials provided and/or bring your own. You might even get your money back
- might use the laser cutter / 3D printer. Ask!
- ask if you need anything!

- Each team documents its own progress (photos, videos, text)
- MA students also document 1 full day ("deliverable", needed for grades)
- Due: 1 week after final presentation
- → Take photos, videos all the time!

Physical Computing
Is an approach to learning how humans communicate through computers
that starts by considering how humans express themselves physically.

How Does Electricity Work?
Electricity is Like Water!
Circuit
(das ist übrigens ein Kurzschluss!)
Let it flow, make it glow!
Electricity
| + | → | – |
|---|---|---|
| "where it comes from" | "where it flows to" | |
| RED | BLACK | |
| ↑ | ⏚ | |
| +, VCC | -, GND, Ground, „Masse”, „Erde” |
Really, Electricity is Just Like Water!
| Voltage U [Volt] deutsch: Spannung | ≈ | Speed |
| Current I [Ampere] deutsch: Stromstärke | ≈ | Mass |
| Power P [Watt] | = | U * I |
| Resistance R [Ω] deutsch: Widerstand | = | U/I Ohm's Law |
A fast, thin shot of water hurts, but does not harm you.
A slow moving flow of water does not hurt, but is powerful.
A fast and big flow of water flushes you away!

Metal Conducts Electricity.
Instead of wires, you can also use:
- Aluminum Foil
- Metal Cases (→ Bicycle)
- Copper Plates / Copper Tape
- Conductive Thread
- Conductive Ink
- Skin (partially)
- Salty Liquids
- …
Be creative.

Experiment
- Measure the battery's Voltage
- Check continuity on different things! (Switches, metal, Arduino Ground-Pins)
Switches & Buttons
On and Off…
No matter where you break it!
DIP Switch
Magnetic Switch
Tilt Switch / Ball Switch
Copper Tape = Switch
Conductive Thread
Conductive Ink
Experiment
- Check continuity on some switches
- Power Supply + Resistor + LED + Button
- Arduino + Resistor + LED + Button
Resistors
Resistors: Codes
Resistors: Potentiometer
Resistors: Potentiometer
Resistors: Potentiometer
Experiment
- Check continuity on some switches
- Check resistance on some resistors
- Check resistance on a potentiometer
- Battery + Resistor + LED
