Thanks! I saw the pager motor and think its cool so I bought it but dont know what to use for so I put on this robot to make it spin the yellow thing around. I also added a green led to this one. my next project is the wall racer and I am having difficult doing it. They relays is so small its extremely difficult to solder everything together.
One more problem I had was One more problem I had was that when I turn it off and turn it on again the robot just doing circle and I don’t know whats the problem.
