| + | This scenario demonstrates how to control the position of a servo motor using Arduino. Servo motors are used for precise angular positioning in robotics and automation. In this lab, a thermistor sensor is attached to the servo motor arm in a way that it can be moved on the front of the fan (DC motor). By triggering the fan, it is possible to change the temperature and so initiate output changes on thermistor readings. | ||
