This is ho scale but applies to most all scale models.
Sliding door using servo motor.
A lcd 16x2 screen to show the doors status 4.
There are two basic motion profiles.
The basic formula is the same for all motors.
For simple rotary applications such as open close operation oriental motor offers a wide variety of reversible ac motors speed control motors stepper motors and servo motors depending upon the needs of your application.
The system includes dc motor which makes door to slides during opening or closing by rack and pinion gearing a lcd to display information state of door an audio buzzer to make sound through the duration of opened door and a controller for controlling the opening and closing of the door as a person or object detected by sensor.
Common formula for all motors.
The door is driven by a continuous rotation servo motor with a pulley system.
There are two hidden push buttons that control the servo motor rotation.
Inside the enclosure there is a normally open mini contact switch no and 5 leds.
Looks cool based on my requirements i synthesised a flow chart.
However use the formulas below when calculating the acceleration torque for stepper or servo motors on the basis of pulse speed.
A simple touch sensor to let me in 3.
Here was what i wanted to achieve 1.
Open close door.
This is a short video demonstrating theuse of small servos to open and close doors and move figures.
Enjoy the videos and music you love upload original content and share it all with friends family and the world on youtube.
As the door slides open the switch goes from normally open to close state turning the leds on.
