I built this kit. I can move wireless the robot forward, back, left, right and stop. I can also take video, turn on and off the headlights. But I cannot move the camera up or down, nor side to side. The ultrasonic sensor is not working either.Can you assist me on what to do? How do I erase the uploaded codes to the arduino and upload a new?
David, I did all that. Only the up/down servo and left/right servo of the camera, and also the ultrasonic sensor that do not work. I attached the arduino sample codes I copied, maybe you can review it if there are errors. These are the sample codes provided in the site.
