    Condition +-.1v from 2 wires to 0-5 for Arduino analog

    My quest has now been to understand coupling and Why AC coupling. In my search I found a wonderful article from the MIT media lab. http://resenv.media.mit.edu/classes/MAS836/bias.pdf . my initial thoughts are for DC coupling, I am trying to measure the pressure and don't expect any...

    Condition +-.1v from 2 wires to 0-5 for Arduino analog

    Thanks for the quick reply. I think I should use an operational amplifier. I was able to connect a General Operational Amplifier to 5volt+ and ground and got was able show a loss of voltage when negative pressure was given to the sensor. It clipped, I believe, when I tried giving the sensor a...

    Condition +-.1v from 2 wires to 0-5 for Arduino analog

    I am toying around with connecting a 236PC 15GW pressure sensor to my arduino board. I am supplying nearly 10 volts to the Sensor and can get +- .1V readings from some simple tests. How do I condition these two lines that give +- .1V to range from 0-5 Volts for the Arduino analog pins.

    Trouble understanding Newtons first law and f=ma

    Your what I could not quite manifest in my mind. Thanks. Got it. Newtons laws are best explained in terms of momentum, some reason F = ma sticks out more in high school text. Force is not an inherent property.

    Trouble understanding Newtons first law and f=ma

    In reading Newtons first law, An object at rest or in motion will remain the same unless acted on by an outside force. also known and understood in Newtons 2nd is Force = mass x acceleration. An object "A" moving at a constant velocity has no acceleration therefor no force. Object "B"...
