I made another circuit to display TV Video output from the Arduino. It uses the TVOut library (documented at the TVOut Arduino Playground) which can be used to output an NTSC or PAL video signal. The circuit is actually just a means of adding three resistors to an RCA video cable. Instead of cutting a …

I created a simple circuit using the LM317 to output 3.3 volts from a 5V or greater input voltage. Why? Because, a number of modules for the Arduino (or Pinguino) take 3.3 Volts. It’s true, some of the Arduinos do have a 3.3V voltage regulator (and thus a source of 3.3V), however, that might not …

There are many Linux (and Windows) programs ‘out there’ that allow you to do serial port communications. However, I needed some things that those programs did not provide (on my Linux system) so I came up with my Serial Port Communication via Python script. If you want something that you can learn from and/or customize …
