··· ··Hello , I am a student in Taiwan.· I am a new user of·Basic Stamp2. I got some problems in using Board of Education (Serial).
········
My problems :·····
······I want to make a auto-moving car, and I· shall to put a LCD module on it. The function of LCD
is to let someone who·use the·car set the·argument of time and the argument of distance by himself.
For instance, if it is static ,two·hours later,I do want to have it· move 200 centimeter in slow and constant speed.
How can I· set the arguments of time and distance in PBASIC ? Could you give me some tips?
··········If· I lacked some components what I need?· Please tell me.
········
········· Thanks a lot. &· Have a good day.·· ^_^

One possiblity is to use a potentiometer to set the time and distance as you've described.
The Stamp command to look at at is RCTIME and its use is very simple. Have a look at the Help file under RCTIME for some sample circuits.

Hi , all masters in robot .
I am only a beginner in Robot.·All i have is boe kit (serial) , 2 servos , one·ssc-32 card and parts of car.
Now, teacher required , my work is to make my car move and stop under my control.(all ideas are ok!!·) <---at least
The deadline is 7 days later .
who can do me a big big big favor?
All replies are appreciated. ^^
If my grammar is fault , please correct me. (Robot and English are both i have to progress.)·

There are many sample programs and tutorials on Parallax's website and you should download some of them to use as a starting point for your project. The tutorials are found by going to the main Parallax web page, selecting the Resources tab, then choosing Downloads, then Stamps in Class Downloads. The "Robotics With The Boe-Bot" tutorial is a good starting point. Under the Resources tab, the Nuts & Volts Columns area is also very useful.
To Mike : The tutorial you recommanded is useful. i am reading it now.^_^ Thank you so much.
Tom , sorry , i can't find RCTIME what you recommanded. Can you tell me how i can find it ?
If someone who have good ideas for me , please reply it. Thanks.~~
If someone who have good ideas to change my car into an auto-moving car ,·i'll appreciate it.^^

If you wanted the car to stay static for two hours before moving,·I suggest having a look at the PAUSE, NAP·and SLEEP commands in PBasic.· You can use these·with an appopriate·FOR / NEXT or DO WHILE loop to extend the times.
One way to make the car travel a fixed distance is to make it move·at a constant speed for a fixed period of time.··This could be as simple as switching on the·drive motors, pausing for a few seconds, and then switching them off again.· You can do this with the PAUSE command if the distance doesn't have to be too accurate.·
You could also use·an optical encoder to measure the distance travelled if you have one, but these are a little trickier to set up.
··· Your suggestion is helpful for me. I'll do what·u say in the near future. Because i am learning some base of microcontroller now.
