Hey,

while experimenting with operational amplifiers, I realized I need some form of visual representation of the voltages and a easy-to-use function generator would also have been nice.

Since an oscilloscope and a function generator would have been overkill for my experiments, I created a arduino based one on my own.

You can find the source code, as well as a release version here:

https://github.com/thomai-d/Scope

Required hardware:
- Arduino Nano/Uno/Mega/atmegaX
- MCP4902 SPI-DAC   (1,30€)

Features:

- 3 channels, 8 bit resolution
- up to 3500 samples per second (per channel)
- Sine/Saw/Triangle function generator
- Control the DACs from your PC.

That looks really cool. So it represents the voltages visually, and the function generator is there for comparison? I suppose I should do some googling. Nice work anyway!
