This week we've been introduced to the world of physical 
computing. Einar has showed us  breadboards, resistors,
potential meters, buttons, photoresistors, sliders++ and a
lot of differenttools that we use mixing all this together. 
Our first task was to handle the solder iron and randomly 
sold different wires to a prototyping- board. The result 
was facinating. After this we made a circuit with a glowing 
LED on a breadboard. We made a power connection with a 9volt adapter and sent the voltage throug a small 
transformer to make it down to 5volt. Further we used a
little resitor and then the LED into ground. And, voila,
there were light!

After this Einar crashed his little RC Formula 1 car,
disassembled the whole thing and ended up with the
essential RC components, the transmitter and the reciver.
Now he shoved us how to make the LED glow by radiosignals.

At the end of the workshop, we tested the Arduino board. 
See picture. With this board we can easely control selfmade 
electronics with our computer by digital and analogue 
outputs and inputs.
