 | | is it possible to use a polarity switch with a RCX input? —Jonathan Wilson
|
| | | Basicly, what I want is a button, switch or whatever on my model that when moved one way causes one input to be sent to the RCX but when moved differently it causes a different input to be sent to the RCX. Should also have a 3rd "off" state. I am (...) (23 years ago, 24-Mar-02, to lugnet.robotics, lugnet.robotics.rcx)

| | | | (...) Use a resistor to make one of the states of the switch read less than a full short. Setup as a light sensor. 0 means off 50~ means one state and 100 means another. This is the basis for alot of the touch sensor multipliers. I am sure if you (...) (23 years ago, 25-Mar-02, to lugnet.robotics, lugnet.robotics.rcx)

| | | | | (...) But... be aware that the 'polarity switch' has only two connectors (for two sets of wires). It's not a '3-way' where you can try to select one of two inputs by moving the lever. The action is forward-off-reverse with one power source connected (...) (23 years ago, 25-Mar-02, to lugnet.robotics, lugnet.robotics.rcx)

| | | | | | | (...) Well the polarity switch can be made to work as a "switcher" that can be used to can input source or output source by wiring it like Hao-yang Wang did in this example: (URL) works great like this, I use it with my RailRacers ((URL) control (...)

I mean this: when current flows in a certain direction, it (...) (23 years ago, 26-Mar-02, to lugnet.robotics, lugnet.robotics.rcx)

| | | | (...) Actually, you want it to be unpowered instead of powered; giving the sensor power will just waste your batteries heating up the resistors. Setting it up as SENSOR_TYPE_NONE and SENSOR_MODE_PERCENT (or SENSOR_MODE_RAW) under NQC would be much (...) (23 years ago, 25-Mar-02, to lugnet.robotics)
