RCX-Oscilloscope

We'll have more on this posted later. For now, I'll say that it's possible to use the RCX as a low frequency oscilloscope by doing the following:

• Connect the signal to an RCX input port. Make sure the signal varies only between 0-5 volts.
• Treating the signal as a unpowered sensor, run the circuit with the RCX datalogging enabled.
• View the data as a graph in Robolab to see the waveform.
