'''Task'''
 
 
The task was to build a small circuit mainly in order to familiarise ourselves with a soldering iron.
 
 
 
'''Work'''
 
 
Tobias Wolf and I constructed a wooden display that either shows the number zero or the number one with the help of a drilled dot matrix and nine LEDs.

To accomplish the change of the number we build a two-way connection; first we put one, two and two times three LEDs each in a series circuit and connected those in parallel. Next a resistor of 330 Ohm was used for the wiring with only one LED and a resistor of 220 Ohm for the one with two LEDs. That's slightly more resistance than needed but we assumed this wouldn't be a problem.
 
 
On top of this we improvised a toggle switch which connects the two LEDs either with the single LED to form the "1" or with the other six LEDs to form the "0".

Last but not least, our wiring diagram:
