The Oscilliscope

     We purchased an oscilloscope at an auction about a month ago, thinking it would be cool to play around with. Basically what it does is measure the voltage over time. The picture on the right shows 2 different voltage over time readings. The bottom one is very much like what my robotic arm would be sending to the servos, each pulse is electricity traveling to the servo, and the width of each pulse is what tells the servo what position it should be in. The dials at the side of the screen allow you to change different variables, so that you can line up the wave with the graticule, and measure it better.

I have to say that I'm rather fond of the way the Oscilloscope looks, it gives a work area a little bit of the 'mad scientist' look.
