Detailed and complete project software assembly prepared by the lift circuit PIC16F84A based on the control card of buttons on the floor with the choice being made door integrated with the built motor drive circuit control ediliry card LEDs on the observations can be made.
Circuit model for testing the operation of the elevator you can see in my video prepared
In addition to logic gates in the project’s elevators.
Elevator Circuit Test
Project model of a lift on 5 floors with a microcontroller pic16F84A. This project was the first to develop when I was introduced to the world of microcontrollers, I now realize that with the new knowledge I gained could have made the program more refined shape, but I decided to leave it as it was cast by a beginner .
I made a model of 8 floors whose dc motor can be controlled with a card that made more than 20 years ago by logic gates, which incorporates 10 integrated circuits and sends the order up and down to another card of 4 transistors available in H, which leads also incorporated the diode bridge and filter capacitor to feed the whole. In the bottom of the image is the card with a 16F84A PIC microcontroller, which program for controlling 5 floors. The only limitation to implement more plants is only the number of pins available to the micro, so for example 16f628 with even cheaper sale can be deployed up to 7 floors. Anyone who knows a little assembler programming vera how easy it is to modify the program to control the number of plants you want.
