Concept of JANS Fast Hands:

We designed JANS Fast Hands as a 1v1 game to allow interaction between the players. All players have 30 seconds to obtain the most points! We built two MDF boxes, each with four buttons, that was wired to a raspberry pico. Each button had four wires: 2 to the LED light and 2 to the power component. The code is programmed to randomly select a light (0-3). Once a light is selected then the button will light up and once the button is pressed then the score count will increase by 1. 

Our idea of JANS Fast Hands remained consistent throughout the semester. However, we did change the position of the buttons various times. In our planning stage, we wanted to have a vertical box with various buttons (Figure 1). Once we began our low-fidelity prototype, we changed the design of our game: 2 horizontal boxes for easy access (Figure 2). 

Materials Used: 

1. Medium-density fiberboard (MDF)

2. 8 Buttons

3. Raspberry Pico Kit

4. Wood Glue

5. Paint

Each MDF box has four buttons that wired to a raspberry pico that is connected to a computer where it obtains python code. The code is programmed to randomly select a light (0-3) to light a button. Each button has a certain number and once the button is selected then it will light up until it is pressed. Once the button is pressed then the score count will increase by 1. 

Key Functions & Components

Input Components: Raspberry Pico Kit and Thonny Code

• We used the breadboard and wires of the raspberry pico kit

• We used python for our code

Output Components: LED Buttons and LCD Screen 

• Our LED buttons were able to function through the code and wiring. Take a look at the figure below to see our wiring for the buttons! Each button had four wires: 2 for the power and 2 for the LED. 

• The LCD screen took most of the power from the LED buttons, so we decided to scrap that idea!
