 | | RC control
|
| I currently own a Legomindstorms that I'm incorporating with the Lego RC cars. I took the car apart and altered the control board so that it can control two motors. This would allow a radio controlled robot to have full movement through the RC and (...) (26 years ago, 29-Jan-99, to lugnet.robotics)

| Hello, The sequence actually starts on the G, like this: PlayTone(392, EIGHTH); PlayTone(523, EIGHTH); PlayTone(659, EIGHTH); PlayTone(784, EIGHTH * 2); PlayTone(659, EIGHTH); PlayTone(784, EIGHTH * 2); A reasonable value for EIGHTH is 16.

| I like 0 to 8 better. Also is there any way to control the frequency at which the PWM works? I find that some of my motors deliver too much at step 1. How about if there was something like: motor( motornum, cycles_on, total_cyles); if you feed (...) (29 years ago, 18-Mar-96, to lugnet.robotics.handyboard)

| As somebody painted out today, the frequency settings for PITCH_Gm2 through PITCH_Am3 (or 23-37) are erroneous. I copied and pasted these from Martin's "Wir sind die Roboter" demo, which seems to be in error, too. A patch to alleviate the problem is (...) (25 years ago, 19-Dec-99, to lugnet.robotics.rcx.legos)
