This Arduino code brings a multi-floor elevator to life (virtually, of course)! It simulates button presses, detects floor sensors, and manages the elevator's movement and those delightful dinging doors.
To build your elevator simulator, you'll need:
| Item | Quantity |
|---|---|
| Arduino Uno (or compatible board) | 1 |
| Servo motor (for that smooth door action) | 1 |
| Liquid Crystal I2C display (optional, but adds a visual touch) | 1 |
| Analog sensors (for call buttons, cabin buttons, and floor sensors) | 4 |
| LEDs (one for each floor to show where you are) | 4 |
| Jumper wires to connect everything | ⚡ |
| Breadboard (optional, for easy prototyping) | 1 |
| Dc motor with controller | 1 |
The connections will vary slightly depending on your hardware, but here's a roadmap:
-
Connect the call buttons, cabin buttons, and floor sensors to analog input pins (A0, A1, A2 in this code).
-
Each floor should have its own LED, connected to digital output pins (Pins 3, 4, 5, 6 in this code).
-
Hook up the servo motor to pin 11.
-
If you're using the LCD display, refer to the LiquidCrystal_I2C library documentation for specific connection instructions.
-
Connect the power and ground pins according to your motor and display specifications (Pins 13 and 12 are used here as examples).
This code is like a well-oiled machine, with different functions working together:
| Function | Description |
|---|---|
setup() |
Gets everything ready for takeoff! It initializes pins, the LCD display (if used), the servo motor, and even calibrates the elevator. |
loop() |
This is the main control center, constantly checking for button presses, sensor readings, and making sure the elevator moves and the doors open and close at the right times. |
printButtonEvents() |
This function (mostly for debugging) shows the current state of the button presses. |
floorReg() |
Reads the call and cabin buttons, keeping track of who wants to go up or down in the buttonEvent array. |
registerFloor() |
Uses the floor sensors to figure out which floor the elevator is currently on. |
calibration() |
This important function helps the elevator learn where each floor is by moving it down to the ground floor and identifying each floor sensor reading. |
movingUp() |
As the name suggests, this function moves the elevator up one floor, opening the door if someone requested a stop there. |
movingDown() |
Similar to movingUp(), but takes the elevator down a floor and opens the door for waiting passengers. |
door() |
Controls the servo motor, making the elevator door open with a flourish and then close securely. |
ledOn() |
Lights up the LED for the current floor, so everyone knows where they are. |
printFloor() |
If you're using the LCD display, this function shows the current floor number. |
mainLift() |
The brain of the operation, this function decides where the elevator goes next based on button requests and the current floor. |
This code is a great starting point, and you can customize it to create your dream elevator:
- Change the number of floors (
N) in the code to match your simulation needs. - Adjust the pin assignments in the
setup()function to work with your specific hardware setup. - Play around with the movement timing (
movementTime) and door duration (doorDuration) in milliseconds to get that perfect elevator experience.
Want to take your elevator simulator to the next level? Here are some ideas:
- Add emergency stop buttons for those "uh oh" moments.
- Implement overload detection to prevent the elevator from getting too crowded.
- Use the LCD display to show additional information like waiting times or a fun animation.
