This project opens and closes a box by using a button on my phone. This is achieved through the use of a stepper motor and the blynk app.
Below is a picture of the final prototype:
I started by setting up my wiring and connecting the stepper motor to my particle argon. The wiring looks like this:
The building process was simple as it involved the creation of the induvial components as well as connecting them together on to the motor.
There are 2 main components that have to be built. They are the T that connects to the stepper motor and the U that prevents the string from getting tangled as it coils around the T. I used cardboard to create both.
After you have made both of these parts you would need to attach the string to the T using tape.
Then you would use more tape to attach the T and the U to the stepper motor as seen bellow:
After this the only thing left to do is attach the string to the box and make sure everything is secure in place.
To use blynk in the project first you will have to make a new blynk project which you can find out how to do at https://docs.blynk.io/en/.
After you setup a new project you will have to create 2 buttons. To do this you first need to create 2 different data streams then use the data streams for buttons.
After you do that you can insert the buttons on the mobile app and it should work when clicked on.
