    Your imagination is the limit of what you can do with PicoBricks!

    With PicoBricks, you can create most games you want using your creativity. For example, making labyrinth games can be pretty fun. With the new version PicoBricks, you can control it with a remote control! 

    If we need to talk about the maze game and how it should be played; players have ability to control the movement of the ball’s movement with a remote control or comparable device, with the goal of reaching a hole or target point. As they navigate through the maze game, players maintain the ball’s balance and overcome obstacles, all while aiming to expertly guide the ball to its destination. The maze game demand focus, hand-eye coordination, and patience, providing players with an immersive and rewarding experience.

    Details and Algorithm

    We’ve specifically crafted the labyrinth game to offer wireless control over a servo motor using PicoBricks and an IR receiver. Our program is engineered to spot signals sent from an IR remote control and then instruct the servo motor to perform various actions such as moving up, down, left, right, or stopping—based on these signals. 

    We’ve meticulously calculated the servo motor’s angles and translated them into precise positions by employing a PWM (Pulse Width Modulation) signal. Our program not only serves as a fundamental example for automation projects and remote-controlled devices but also includes a mechanical design generated through a 3D printer. Those interested can delve into the code to gain an in-depth understanding of its functionality and utilize it for similar projects.

    If you prefer, you can create your own maze game and print it on your 3D printer, or you can download the STL file and print it on your 3D printer using the download button below.

    What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
