candy dispenser models
Nowadays a lot of children suffer from hyper activity, overweight and diabetes, so i thought about making a candy dispenser box with password and with a settled time, so that the parents can control the amount of candies that a child can take daily at home.
By this, the box won't open again after giving the child a candy till next day as programmed.
2- Describe the project idea and general features. How would it work?
2- Describe the project idea and general features. How would it work?
the project consists of a box full of candies, an arduino to control it.
it will have a servo motor to control the lock of the box.
you should enter the right password on the keypad to open the box, and the password will appear on the LCD screen.
After the box will be opened, i will program it to not open again for several hours even if the child entered the right password and a message will appear on LCD "come after 5 hours" for example.
By this i can control the amount of candies the child takes daily.
3- Sketch your project: You may use pen and paper or a simple sketching tool like Microsoft Paint or Photoshop

4- Describe the Technical Modules that your project consists of
Construction Parts
control box will be designed by fusion 360, and fabricated using laser cad, made of wood with thickness 3 ml
candy container will be a plastic jar
door that opens and close will be designed with plastic (pLA) using fusion 360, fabricated using ultimaker cura
Input
(Sensing, Tactile Input, and/or Graphical Input)
Sensing: keypad to enter password
Action
(Physical and/or Graphic)
Graphical Action: The device display a message through a graphical screen (LCD)
Physical Action: servo motor will open and close candy door
Brain
Arduino UNO board will act as the smart device's brain that processes the Input and send orders to perform the Action
Power Management
My device contains (battery or adapter) as an independent power source
5- Create a cardboard prototype of your project, demonstrating the project face as well as internal movements and mechanisms. Include a demo video and photos of the prototype.

6- Categorize your project’s User Features into: Minimum, Complete, and Nice-to-have features. List the required action and input components per feature.
6- Categorize your project’s User Features into: Minimum, Complete, and Nice-to-have features. List the required action and input components per feature.
Minimum Features: are the least amount of features that would demonstrate the coverage of all the technical modules and their complete integration
Complete Features: are the set of features that will complete your original project objective and vision
Nice-to-have Features: are the extra set of features that will make the project cooler, yet they need extra time, effort, and/or resources to finish
Minimum User Features
Action: servo motor will open and close candy door
Sensing: None
User Input: keypad to enter password
Complete User Features
User Input: keypad to enter password
Action: servo motor will open and close candy door
OUTPUT: LCD to display "open" and " not now come after ... hours"
Nice-to-have User Features
Sensing: timer to show remaining time for child to take candies again
Buzzer to make alarm if it's not the right time to take candies
