I'm in need of help. I want to teach some teenagers how to run a continuous servo in either direction for a specified amount of time with an arduino. This is kind of step 4 of 10 if you will, but if I can't teach them step 4 then I can't teach them steps 5-10. So I'm asking all of you for the most basic code to accomplish this task. I'm picturing an "if-then or else" command that will tell a servo to move in one direction for a specified amount of time if an analog sensor reads above a certain reading and moves in the opposite direction if reads below said reading. I've been looking for code that would work for me, and apparently coding an arduino to run a continuous servo is not as simple as one would think. Here is an example of some code I found on the forum (scroll down to comment #9 for the code in question), but I thought maybe there was a more basic way to accomplish what I want...maybe there isn't? Anyway, I'm a bit desperate at this time.
