An Arduino Nano experiment

Using the Arduino Nano Brick it is possible to built very complex circuits
using our brick system. At the bottom of the image an OLED is used
for display and its connected at the I2C bus with a D/A converter
bricht. The D/A converter offers a 12 bit resolution. The brick also has
some options on the output voltage range of 0-5V, 0-10V, -5V..5V und
-10V .. 10V.
The program example from the arduino set manual, outputs a sin function
at the D/A converter which is connected to both inputs of the Ardino
Nano A0 und A1. Only A0 is used as A/D converter and the result
displayed in numerical form on the OLED as well as a graph which shows
the time behavour.
