Help with servo
July 1, 2008
hi, first of all: sorry, my english is so bad. and I mean .. BAD.
I am a beginner, and I have some problems with servo controller! I fallowed "how to make your first robot" by fritsl (great fritsl..!!), except I used a srf05 not a ir sharp sensor device. (there's an other problem, I connected srf05 like http://letsmakerobots.com/node/66 but I can't insert a functionally command string in the fritsl's program that let it work, although it seems to work with the node 66's code)
I connected the servo using a standard servo connection (soldering an extra pin to output 0)
When I upload "servo 0, xxx" the servo does nothing. When I disconnect it from the picaxe 28x1 and than connect it again it takes a little turn. When I upload the program of the fristl guide the gear motors go on, but the servo turns on its right, than takes a pause.. than turns on its right again, and so on.. and so on.
I supposed that the problem is that I don't bought PICAXE servo upgrade pack and I haven't the "yellow chip", SO I LEFT THE DARLINGTON-DRIVER IN .. .. but I can't figurate out what the "yellow chip" is and I can't say its name to the electronic's shop! .. .. I don't understand what is the function of this yellow chip too..
could you help please? thanks all..
