which was my original problem. I have a AT30TS75 temperature sensor which only has I2C. I could not get I2C working on pin 21 and 22 using Arduino IDE, which I believe are the default pins. I was wondering if there is a way to change the pins from 21 and 22 to 32 and 33. How...

I'll provide some links to the Arduino reference page, Wikipedia, and some other interesting sources. If you want to know more about about a certain subject, these are great places to start. Again, if you don't understand a word of those links, don't worry, it is absolutely not necess...
Some time ago I was working on an Arduino project and I needed to see if the output signal was into compliance with the specifics. Thus I spent some time on the internet looking for Arduino Oscilloscopes already implemented, but I did not like what I found. The projects that I found wer...
