Week 0 - Journal

Smart toy (What a final project would be like)

Tell us about your task for this week.

Smart Toy

This toy may seem simple, but there's a lot happening inside it.

Essentially, it displays a counter on the screen. If you get the number correctly, you win. However, the speed of the counter depends on how you tilt the toy, as an internal sensor controls the pace.

Additionally, you can connect it to your PC or laptop to use it as a controller for a more exciting game. In this game, you need to hit the green area in time as the slider moves back and forth.

tools and kit

Arduino UNO
LCD Screen
Tilt Sensor
Buzzer
jumper wires
laser-cut wooden parts to make the body
bunch of bolts and nuts

Design/Preparation Process

Explain the design and/or preparation process of your assignment. How did you use the tool or software to design and/or prepare your assignment before fabrication/implementation?

Circuit schematic

First, we organize the components to simplify the process. We start by connecting jumper wires to the input and output components: the LCD screen, sensor, and button. Then, we connect these wires to the Arduino as shown.

Implementation Process (assembly)

Now that we've completed the electrical connections, it's time to attach our components to the wooden parts. These parts are laser-cut to create a 2.5D model when assembled, which is one of the coolest techniques we learn here.

The Arduino is fixed to the back, the button is placed at the top, and the tilt sensor is positioned at the bottom of the body. We then enclose it with the screen face of the body, securing everything with bolts, and nuts.
