Introduction
Understanding Servo Motors and it’s working
Servo motors are part of a closed-loop system and are comprised of several parts namely a control circuit, servo motor, shaft, potentiometer, drive gears, amplifier and either an encoder or resolver. A servo motor is a self-contained electrical device, that rotate parts of a machine with high efficiency and with great precision. The output shaft of this motor can be moved to a particular angle, position and velocity that a regular motor does not have.
circuit
Code
- From event palette drag when flag clicked block
- From arduino palette drag set servo on() to ()
- Add forever block and insert if else block in forever block.
- Read the status of IR senor on pin 7 of ardino using read status of digital pin()
- If the sensor value is HIGH then servo must rotate 180 for 3 seconds otherwise it will remain at 90 degree
