Many people are trying to make a variety of DIY projects to meet their daily needs. A main example is that room automation. Although many room automation settings have a higher cost, we can't make it cheap. Can we use ARDUINO's beginners toolkit? My answer is "Yes, it is possible!"
Supplies
Arduino or any other microcontroller
Stepping motor with motor drive
servo motor
Screwdriver (diameter: 8mm & length: depends on you) with copper nut
Coupler (8mm * 5mm)
External power supply (optional)
Cardboard or foam board
Infrared receiver and remote control
electric wire
Step 1: How to control the switch?
Usually many of them prefer to use relays to control what internal circuits for your housing. If you are not good at handling it, avoid using it!
In order to make this project simple and different, I use one of the core components used in 3D printing. This is the linear actuator. Here our linear actuators will control the vertical motion of the servo motor, and the servo motor is used to open and close the switch.
For example: - Turn on the light
We must find a stepper motor that must be rotated to reach the switch.
We have to set the servo must turn much to turn on the value of the switch.
After a few seconds of delay, we must set the server back to its initial position.
Stepping motors must return to its origin (- rotation).
According to these conditions, our procedures are as follows:
IF (lights = "on") {
MyStepper.set (Rotate); // How much the step the switch? / t t r? 网? @ h m t TO REACH THE
MyServo.write (); // how much the servo haas to turn in Order to Turn on the switch?
DELAY (1000); // Wait 1 SECOND
MyServo.write (); // set servo to initial position
MyStepper.set (-ROTATE); // Stepper Motor Turns Back to Initial Position
}
Supplementary description:
Even if the stepper motor movement is accurate, it cannot know how much it is rotated, because if a power failure occurs, it does not return to its initial position and treats the current point as an initial location.
In order to solve this problem, we must add another 3D printer core component called a limit switch. Since the wire DIY limit switch is easy, it is not bought!
If you want to add a DIY limit switch, you can delete this code mentioned above. Since the program is created in this way, the stepper motor must return to its initial position after the command is issued.
MyStepper.set (-ROTATE); // Stepper Motor Turns Back to Initial Position
Step 2: Construction and testing
What is created here always depends on how you control your switch.
As far as I said, first of all, I must cut off the layout that will be installed to the distribution plate.
Then I have to stick the stepper motor and a small bracket made of cardboard to keep the screw in place.
Since the diameter of the stepper motor and the screw, I have to connect them with the help of the coupler.
After that, I have to create a bracket for our servo motor, which is connected to the copper nut (Figure 4).
Since our servo bracket is free to move, I have to use a hierarchy to add a support structure.
After all, I have to add my DIY limit switch, which will be on top. When the wire is placed on the servo bracket copper nut, the stepper motor is turned off.

Make sure that your structure is sufficiently robust, especially the bracket of the servo motor. If it is not so powerful, it may not give you the right result!
Also make sure there is a small gap between servo and switches. This will ensure smooth movement.
When testing, people may find that even if the servo motor is rotated, it may only perfectly perform a command, otherwise it does not perform any operation, as shown below. So sometimes you may need some adjustments to the speaker itself. (I don't know what the speaker means? Click here!)

Step 3: Finally, programming
After making and testing your model, it is time to wirelessly control it. Since the Arduino UNO beginner suite provides an IR receiver and a remote control, our path is perfect. However, if you don't have it, you don't have to worry. Because this is just a start. They have many ways to modify this project. So please continue to pay attention!

Since I am Arduino programming initiator, I tried to make this code as simple as possible, so that you can understand what I wrote.
Supplementary description:
Let us divide the entire code into two parts: step into the initial position and infrared remote control
Stepper initial location
In Void Loop, I start with IF condition, which indicates that the stepper motor will rotate clockwise until it receives the HIGH signal from our DIY limit switch. (Use the reason why the DIY limit switch mentioned in step 2).
Infrared remote control
E.g
If our IR receiver receives the "0xef807f" signal and our Switch1 is in the "closed" state, then our stepper motor must take the -21000 step to reach Switch1 and the servo must rotate 30 degrees to open the switch, and delay 1.5 After the second, our servo system will move to its initial position and explain that Switch1 has been "opened". If our IR receiver receives the "0xef807f" signal again and Switch1 is in the "ON" state, then our stepper motor must take -21000 step to reach the switch, and the servo must rotate 180 degrees to turn off the switch, and delay 1.5 Seconds our server will move to its initial location and declare that Switch1 is in the "off" state.
The same conditions are also applicable to all switches.
Here, we did not rotate the stepper motor, because when the Switch shell ruptured, our DIY limit switch will have a "low" value, which will rotate the stepper motor. Therefore, we will encounter a problem, that is, we can only send one IR signal at a time. In order to send another signal, you must wait until the servo bracket reaches its initial position.
