timer/stopwatch

Archiver

Hi,

does anybody know where I can find a stopwatch or timer to time a
robot running around on the ground?

I don't check this egroup that often, so would you please reply to me,
fractal@w..., thanks.

thanks

Hi Fractal -

You need to be a bit more clear with your requirement.

Here are just SOME of the questions you need to consider:

How long a period of time are you wishing to measure ?
Will this be used with a Stamp ? If not, which processor ?
How accurate does the measurement of time need to be ?
What type of interface do you need -
serial; I2C, SPI, Microwire, MicroLAN (1-wire)
parallel ???

Are there any packaging requirements, and if so, what are they ?
DIP, SMT (TSOP,TSOC, etc)

Voltage(s) available ??

Beyond that - are alarms necessary, or will you take care of that in software ?
If so, how many are required ?

Is an RTC facility part of the requirement, or is elapsed time sufficient ?

I'll stop here, but you REALLY need to supply more information, to find a
timer which meets your requirement, and fits with your project/platform.

Hi Bruce,

First of all thanks for all of your help with my servo questions. I
finally have the modifications made so that the robot SX28 TechBot
Stamp I is running at least in one direction.

I'm looking for a way to time the run of the robot over a fixed
distance. This will allow me to measure the actual velocity of the
bot.

The period that I wish to measure ranges from fractions of a second to
5 seconds. I am using the Byte Craft Compiler with the robot attached
to the computer to run the robot. The robot starts rolling when I push
the 'Run' button in the Byte Craft Compiler and stops when I push
'Stop'. I am measuring the time it takes the robot to traverse an 18
inch length.

I would like the measurement to be accurate to either hundredths or
thousandths of a second.

Perhaps a clock that runs on the computer that I can use as a stop
watch? Even better would be a stop watch that would start and stop
when I clicked the 'Run' and 'Stop' button in the Byte Craft Compiler
software.

I hope that this is enough information.

thanks
