Arduino Project: GiocattolINO
In this report, It will be shown how to create Giocattolino. It’s about a remote-bluetooth controlled car with the Arduino board and some raw materials.
Before talking about the project, it’s necessary to spend a few words about features that we had to follow:
- Use an Arduino board (UNO, Leonardo, 101);
- Use an input sensor;
- Use at least one interfacing output
- Use at least one device, which wasn’t explained at lessons
- Create a project that can solve a problem in general.
Step 1 – The Idea
In order to make GiocattolINO, it’s necessary to follow some phases: at first, find the idea; It’s always difficult to create something that is going to be useful into our life. In this case, Giocattolino’s objective could be very easy: to let play everyone who wants to have fun during his/her free time.
Step 2 – Key elements
It’s time to write the bulleted list, where there are all the materials needed. Then, it’s recommended to learn about the function of the sensor (HC-05) which is going to be used, but, thanks to some research on the internet, it will be easy to handle it.
Step3 - Flowchart
Step4 – Sketch
The sketch is an Arduino program where the operator writes, following a specific language code, what the prototype has to do. Thanks to this operation, we will interact with GioacttolINO which is connected to Arduino.
Step5 - Design
After this process, it’s necessary to draw the car base. It’s entirely designed on Autocad. Then you have to assemble the structure with the wheels and the other components, you can use a simple glue or if you want to have a strong structure, you can use hot glue.
Step 6- Electrical connection
How does it work?
GiocattolINO moves forward, backward, turn right or left thanks to a smartphone, or better, an app. When we want to play with it, we will suffice to open the app, link the telephone with the HC-05 module. The app will be sending the controlling data packets to the Bluetooth module, and the game is done! Meanwhile, when the car reaches a physical obstacle, the led will light up.
