AUTOMATION OF A GARAGE DOOR. When we press the START button, a motor is activated that by means of a gear system makes the door rise (simulate the door rise time with a 5sec timer). There is an upper limit switch (FCS) that indicates when the door has finished opening. A sufficient delay is established for the vehicle to pass through the door (15 sec), during the time the door rises and remains open, an L1 lamp must blink at a certain frequency When FCS is activated and after the T count 15 sec , the motor is operated in the opposite direction so that the door lowers simulate the descent with the 5-second timer The door continues to descend until it activates a lower limit switch (FCI) that indicates that it has closed and in which case It returns to the initial state, when the door is lowered, the blinking frequency of the same L1 lamp that they used will be changed (the frequency can be whatever you want)
