Electronic Speed Control???
Archiver
Posts: 46,084
I have a question? Has anyone successfully used a Basic
Stamp with an Electronic Speed Control? (used with RC Cars)?
I am having an issue of accuracy with the servo running the
manual speed control. I give it a pulse one direction and an
equal amount in the opposite direction, however; it never comes
to rest in the same place. Which makes the manual speed
control useless.
If no one has used one with the Basic Stamp, does anyone
believe that you could possibly use it in conjuntion with the Basic
Stamp??
Best regards,
Karl

power, especially if they drive gears.
Secondly, they will stop differently going different directions. This may
also have to do with weight shift and traction as far as driving a vehicle.
You may have to tinker with the code to come up with some timing to make the
car go forward and back the same distance.

only talking about the servo not rotating back to the same
position. I have been monkeying around with the code and
cannot come up with the right timing for the servo to move the
speed control forward and backwards and end up in the same
position each time.

sufficient time for the servo to get to where you told it to go. In other
words, you have to send the command to the servo more times to get it to go
from 0 to 90 degrees than from 0 to 45 degrees. Some servos may take longer
to travel one direction than the other, so you may have to factor this in
also.
