Sliding Door Using Servo Motor
Here was what i wanted to achieve 1.
Sliding door using servo motor. There are two basic motion profiles. As the door slides open the switch goes from normally open to close state turning the leds on. This is ho scale but applies to most all scale models. A simple touch sensor to let me in 3.
Inside the enclosure there is a normally open mini contact switch no and 5 leds. Open close door. A lcd 16x2 screen to show the doors status 4. 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.
Pic since i did not have a mosfet or a transistor that can control high current and voltage i used a servo to press a mouse button. The basic formula is the same for all motors. The door is driven by a continuous rotation servo motor with a pulley system. 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.
Minimal effort to open a door 2. Common formula for all motors. 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.
There are two hidden push buttons that control the servo motor rotation.
