Week 7

Ideation

I had a terrible mind block this week, couldn't find any unique ideas. but at the end and as usual, an idea of a game just pop up in my mind 😅

so I searched all night for the closest idea and how to make it. there are plenty of projects like this and that's one of them

Tool Chain

Tinker cad to simulate the circuit before implementing it

Arduino ide to write code and upload it to the board

Small breadboard to connect all components solderless / used mini one at the end to save space

Some jumpers

3 Push buttons to play the game

3 pin Switch instead of mini slide switch to be more user friendly

Arduino UNO r3 to control all the components with code

KY-017 Mercury tilt switch to second mode

16*2 lcd with I2C module

Pen cutter to cut precise pieces

and of course some cardboard to make the body.

scissors to … cut ofcourse 😐

Tape

and glue gun to assembly

Mini drill to make some holes

Design/Preparation Process

First I put the 3 push buttons and the piezo

every component connected to the GND and the other terminal connected to Ardunio bins to take or give the signal

Second, I put a slide switch to control the mode and a tilt switch for the second mode

and at last, a screen to present the winner

Start the code by including liquid crystal i2c library, then define each pin with a name (variable) to easily change it if you want

Define the pin modes in void setup

then starting the void loop

simply, if the mode is switched to 1

then the tilt mode is activated, the LCD print Pick me up, and you will win if the tilt sensor get is on (1), then the LCD print you won and gives a peep sound

then finally a counter with a random number start and blinks the LCD with WAIT word till it repeats itself again

and the other mode has the same features but unlike the tilt sensor you have to click the button fast and then it the winner will show on screen (only the first one who pressed and if anyone else press after it won't affect anything)

then the same wait with random counter and repeat

Development/Implementation Process

Start with wiring and uploading the code and test all the functions

then cutting some cardboard for the body and put the components in there place, and choose the mini breadboard for saving the space

complete the wiring and put all the remain components

then collect the upside and body together with screws and nuts

at the end, doing some flexible parts to easily control it

and let's play!!

Overcoming Challenges

Didn't know how to connect KY-017 as a tilt sensor so i figure it out through this tutorial

second challenge was to connect the mini push button without a bread board, I figured out that when jumper plastic cover removed, I can connect the button legs (can tight the female a little bit in some cases)

I didn't know I can use the on/off switch instead of the slide switch 😅

and the last challenge was that the small button was not easy to play with, so I cut another peace of cardboard and make it flexible from the angels to make a big surface to press
