Hi, i have some questions about PWM and encoder. I made following tests: 1) Speed : motor(0,100) my encoder count f.e. 20clicks / per second 2) Speed: motor(0,50) my encoder count f.e. 15clicks / per second 3) Speed: motor(0,40) my encoder count (...)

| | IR Transmit ?!? HELP

I recently assembled a Handy Board, everything is perfect except for the IR Transmitter. The IR Tx LED does not light. It is not the LED itself because I replaced it. I can't seem to figre out what's wrong. Please help. Thank You Peter Eacmen (26 years ago, 22-Apr-98, to lugnet.robotics.handyboard)

Hi, I saw your robot at the Trinity fire fighting contest last Sunday. It was neat, and very animate. I was curious to know if you had figured out why it did what it did during your first run (?). And, what type of sensor were you using on the rear (...) (26 years ago, 22-Apr-98, to lugnet.robotics.handyboard)

Why does it seem like everyone except me needs a pullup resistor and perhaps a capacitor somewhere to operate the Polaroid? I've never had any problems without any of these components. ??? The first time I connected the sensor, it worked perfectly. (...) (26 years ago, 22-Apr-98, to lugnet.robotics.handyboard)

Has anyone tried to use one of the TI tsl1301 or 1401 linear sensors with the HB. I ended up with a few but am having a tough time trying to figure out what the data sheets are trying to tell me. Not real clear (to me). Bruce A. Moore (26 years ago, 21-Apr-98, to lugnet.robotics.handyboard)

Are you using a pullup resistor on the ECHO pin? If not that is your problem. The ECHO output is an open collector driver which requires an 4.7 K pull-up resistor between the output and Vcc. The pull-up is necessary for connecting the module to a (...) (26 years ago, 21-Apr-98, to lugnet.robotics.handyboard)

hi from France, I already have a handy-board running with a 11A1 chip and I plan to adapt the circuit for a 11F1 chip, with the same memory map. Does someone have any experience about running IC with this chip? Will it work with the pcode_hb.s19 (...) (26 years ago, 21-Apr-98, to lugnet.robotics.handyboard)
