 | | Re: Powered Sensors
|
| No, the RCX knows nothing about the diodes. That is why devices like the light sensor only send a current signal in the range 0 - 0.32mA back to the RCX. This current then creates a voltage drop across the 10k reference resistor with respect to the (...) (22 years ago, 7-May-02, to lugnet.robotics.rcx.legos)

| Thanks a lot Ralph, And I'm sure you're right. I tried this: 10000 VALUE CTR : test 100 0 DO I CR . CTR 0 DO LOOP LOOP ; For CTR > 11000, the numbers are displayed one at a time. Below 11000, they're displayed in batch. So, it probably means that (...) (22 years ago, 3-Jul-02, to lugnet.robotics.rcx.pbforth)

| Greetings helpful companions. Now that I've buttered you up, let's move on... I've built a robotic arm using my RCX 1.0 brick. I'm controlling it via my computer with LeJOS (not important, I think). What my issue arises is if my arm rotates, the IR (...) (19 years ago, 4-Aug-05, to lugnet.robotics.rcx)

However, the return signal the RCX wants to send to the tower isn't transmitted across the mirror. Since you mentioned leJOS and (...) (19 years ago, 8-Aug-05, to lugnet.robotics.rcx)
