“electrons have a tendency to go from a point of greater electrical energy to a point of lesser electrical energy”

“The point of lowest electrical energy is the earth itself, which is where we get the term “ground.””

“If you build up enough electrical energy, electrons will flow through any conductor, even air.”

“A switch is a break in the circuit that stops the electrons from flowing. By closing the switch, you close the break in the circuit and allow the electrons to flow again.”

“There are three basic electrical characteristics that come into play in every circuit. The relative level of electrical energy between any two points in the circuit (for example, between power and ground) is called the voltage. Voltage is measured in volts. The amount of electrical energy passing through any point in the circuit is the current. Current is measured in amperes, or amps for short. The amount that any component in the circuit resists the flow of current is called the resistance of the component. Resistance is measured in ohms. Voltage, current, and resistance are all related, and they all affect each other in a circuit.”

(just relevant when I do the “extended” version)

what sensors do I use?

a “capicity sensor”

how do I use them it?

there will be a counduction to a couple of places/cities on the map. by touching the conductor data is provided to the arduino

what kind of processing/computation will be needed?

intensity of touch, finding a good threshold value for a yes/no operation

what platform do I choose for that?

arduino

what actuators will I use?

a: stepper motor (clockwork), b: LEDs

how do I control the actuators I use with the computing platform I choose?

every conductor is linked to a city. by touching the conductor, the code finds the right (online-) database (=time and weather) and

a: turns the motor in the right ankle
