ObjectiveThis lesson will teach you control the servo by infrared. Equipment
Servo is a set of automatic control system which consists of DC motor, gear set, sensor and control circuit. By sending a signal, the output shaft will rotate specified angle. Generally servo has a maximum rotation angle (such as 180 degrees). The mainly difference between a common DC motor is that DC motor is circular rotation, servo only can rotate within a certain Angle, can't rotate as circle (digital servo can switch in the servo model and motor model, doesn't have this problem). Common DC motor can't return the rotation angle information, and servo can be. Usage is different also, common DC motor is made power with the whole circle turn, servo is used to control an object to rotate a certain angle (such as robot joints). SchematicIn schematic, the black line is the ground wire and need connect to GNU, red line is the power line to 5V voltage, the blue line is the infrared receiver signal line, the yellow line is the servo signal line.
