How we made the sliding switch:

Theoretical plan:

Our realisation:

Material list:

- cord/string

- 1 spring (not too strong)

- 3 fasteners

- 1 small ring fixed support

- 1 small ring

(- magnets)

We tried to connect and display a message on the 8X2 LCD screen through the ESP32, but it did not work for several reasons:

• the ArduinoIDE app doesn't detect any screen
• the ESP32 is really complicated to handle since the wires leave all the time and the screen is glitching a lot since the power is not well fixed/delivered to it

We will try again after researching even more.

For the box, we're thinking about the mechanism to open and close it.

We're thinking of a lock like a chest or a screw process.

An instruction book that lights up when opened.

Opening system that acts as a switch:

Our solution to integrate this into our project:

battery:

• coin battery
• finger battery
• rechargeable battery

Main idea: get two hollow domes and fix them together. 

Problems: the surface is circular: how can we fix the screen? And how can we fix the components inside the domes?

Summary of the session:

• Working on wirying the LEDs and the touch sensor
• Research on the mechanism of greeting cards to reproduce it on the instruction book
• Research on the LEDs, buzzer, switch and battery

Summary of the session:

• uploading our code on the ESP32 through Arduino IDE for the touch sensor and for displaying a word on the screen
• listing all our components
• looking for ways to make our project open and close easily
• exploring new ideas (like using an accelerometer to detect shaking and displaying the answer of the M8B)

List of the materials required to construct our Magic 8 Ball:

• 0802A LCD screen or an black and white picture screen
• ESP 32
• board
• wires
• touch sensor
• resistors
• LEDs (in bands)
• accelerometer
• outside box 

To display the word "Magic 8 Ball" on the screen:

• We needed the "LiquidCrystal" library on Arduino IDE to be able to connect the 0802A LCD screen. 
• We have to connect the LCD object with the pins RS, E, D4, D5, D6, and D7 of the 0802A LCD screen.

Requirements:

• Design For Manufacturing (= optimasing, reducing the cost without reducing the quality)
• Design For Assembling (= easy to assemble, we're required to be able to open our project freely, so we won't use any tape or glue)

Summary of the session:

• connecting the ESP32 to our computers through Arduino IDE (connecting it to the WiFi, understanding how it works)
• modelisating our circuit on TinkerCard
• collecting pieces of information on how to create our Magic 8 Ball and for it to be efficient
• listing all the components we'd need to carry the project

Positive points:

• We managed to get all our components.
• We understood how we could make the Magic 8 Ball.

Negative points:

• We spent a lot of time figuring how to make the ESP32 work and how to make it available on Arduino IDE.
