Circuit Schematics

All integrated circuits (ICs) are equipped with a 0.1 µF monolithic ceramic capacitor connected across their terminals. Additionally, each board features two capacitors: a 10 µF tantalum capacitor and a 100 µF electrolytic capacitor. The START BUTTON serves as a digital input, activated by the user to initiate the game, utilizing a momentary switch. A vibration motor is incorporated to deliver haptic feedback.

In this circuit design, the presence of the 0.1 µF monolithic ceramic capacitors across each IC serves to filter high-frequency noise and stabilize the power supply, enhancing the performance and reliability of the integrated circuits. The choice of a ceramic capacitor is advantageous due to its low Equivalent Series Resistance (ESR) and high-frequency characteristics, making it suitable for digital applications.

The additional capacitors—10 µF tantalum and 100 µF electrolytic—are strategically placed across the board to ensure adequate power supply decoupling. The tantalum capacitor, with its stable capacitance and size efficiency, is effective for filtering lower frequency noise, while the larger electrolytic capacitor provides bulk energy storage to manage transient loads during operation, ensuring that the system remains stable under varying load conditions.

The START BUTTON is a critical component of the user interface, designed as a momentary switch that, when pressed, sends a digital signal to the microcontroller or processing unit to commence the game. This switch is typically debounced either through hardware or software to prevent false triggering from mechanical bounce.

The inclusion of a vibration motor adds an interactive element to the device, providing tactile feedback that enhances user experience. This motor can be controlled via a transistor or a dedicated driver circuit, allowing for precise activation in response to game events, thereby enriching the overall engagement of the user with the game.

This circuit design exemplifies a well-thought-out approach to integrating power management, user interaction, and feedback mechanisms within a compact and efficient electronic system.All ICs have a 0.1 uF mon-ceramic capacitor across them and there are two capacitors (a 10 uF tantalum capacitor and a 100 uF electrolytic capacitor) across each board.
