 | | To all sensor developers, why use voltage drive ? —Stef Mientki
| | | | Hi, Why is everyone using a voltage driven cirquit when devolping a RCX sensor-cirquit, while the RCX sense input is in fact a current sensing input ? Ok, I admit, until short I also copied the schematic everyone is using. But I now think the (...) (24 years ago, 2-Mar-01, to lugnet.robotics.rcx)

| | | | | | | no, but you can consider it as a "blackbox" and measure it's behaviour by Ohm's law. (...) Stef Mientki (24 years ago, 3-Mar-01, to lugnet.robotics.rcx)

| | | | | hi Michael, thanks for you reaction. (...) So here I disagree with you , you are correct if you'r saying the inside AD-converter is measuring voltage, but we're not dealing with the AD-converter alone, but with a combination of the AD-converter, the (...)
