Food Delivery Call

With a pandemic like this one, people now try to avoid physical contact, indicating that going out becomes a challenge for certain individuals. In order to solve this issue, several either make an order for food like food panda or uber eat, or they order raw vegetables and fruits. However, even with this delivery, they often do not ring the bell and just place all your clean, fresh, breakfast on the floor where all the germs are. Do you want your food to get dirty on the ground? Do you have the time or the energy to wait for them all day? If your answer is no, this machine may suit you! Introducing the: delivery call machine!!!!!!!

x1 Arduino Leonardo

x1 ultrasonic sensor

x1 buzzer

x1 long jump wire

(unlimited) wires dependng on how far you want the buzzer to be

x1 USB cable

x1 roll of tape

x1 pair of scissors

- Try choosing more distinct colors to separate the wires from one another

- The buzzer's wires can be extended as long as you want

As beginners, be sure to follow the diagram for where each wire and component on the Arduino Leonardo goes. If later on you test it and it does not work, remember to check:
- whether your jumping wire connects the GND with negative - components that connect the entire circuit are connected vertically --> circuit runs vertically, not horizontally - whether the RGB LED's legs are all plugged in properly(same goes for all the other wires)

Since this is a project for beginners, I already wrote the link for you. Feel free to just download and use it right away. Remember, if you are adding any new elements to the code, look at the notes behind // by the previous author indicating what each part is coding for. Make it better to suit you even more !!!! :) Also the other picture besides the code is Ardublock if as beginners you don't know how to write code, Ardublock is another tool to make this project way easier!

The outer shell depends on you, in my case, I decided to make a container to prevent it from being too vulnerable against whether or outside factors like insects or animals. Therefore, the entire Arduino Leonardo board was hidden inside a box and the sensor only reveals the part where it requires to sense something. For this project's case, since everything except the wires connected to the buzzer was inside the box, it is important to place a plate in front of the sensor (remember anything is fine, but it has to be lower than the sensor) so that the food they put won't go into direct contact with the floor.

1. Prepare a small box just around the size for the entire board to fit in

2. dig a hole the size of the USB cable and also 2 holes for the sensor's sensing part

3. dig a little hole so that the wires for connecting to inside the house or wherever you want the buzzer to be can get out

4. Find a lid or make your own and cover it up to prevent insects or weather for damaging it

5. Make a sign telling the food delivery to place the food onto the plate and not the floor

*remember, if you want to make your own box, it also works, as long as you conceal all the important components for the machine to work

YOU'RE ALL DONE!!!!!!!!!!!!YAY! Let's watch the final video!!!!
