| + | ==== Project Structure and Feature Interaction ==== | ||
| + | |||
| + | === OLED Display (Adafruit SSD1306 128x64) === | ||
| + | Shows the main menu, game instructions, user prompts, and results. | ||
| + | Provides all visual feedback to the user during setup and gameplay. | ||
| + | |||
| + | === HX711 Weight Sensor + Load Cell === | ||
| + | Accurately measures the weight of objects placed on the device. | ||
| + | Used in both games to set or check the weight value. | ||
| + | |||
| + | === 4x3 Keypad === | ||
| + | Lets the user navigate menus, select game modes, and enter numerical guesses or commands (such as start, confirm, or return to menu). | ||
| + | |||
| + | === Buzzer === | ||
| + | Outputs audio signals for feedback. | ||
| + | Plays different tones to indicate success or to help the user get closer to the target weight in the matching game. | ||
| + | |||
| + | === Arduino Board === | ||
| + | Central controller that runs the main program. | ||
| + | Reads inputs from the keypad and weight sensor, updates the display, and controls the buzzer. | ||
| + | |||
| + | ==== Functionalities Validation ==== | ||
| + | To test the weight sensor, I weighed an object with a kitchen scale and checked if the values matched. | ||
| + | |||
| + | ==== Sensor Calibration ==== | ||
| + | For the weight sensor, I used an object with a known weight (75 grams) and observed the sensor reading (approximately 148,500). Based on this, I calculated the calibration factor as (sensor_value / actual_weight). | ||
| + | |||
| + | ==== Optimization ==== | ||
| + | |||
| + | Used modular functions for clarity and easier maintenance. | ||
| + | |||
| + | Limited display updates to only when changes occur, reducing flicker. | ||
| + | |||
| + | Grouped hardware initialization in setup for faster start. | ||
| + | |||
| + | Provided immediate feedback with the buzzer for better user experience. | ||
| + | | ||
| + | Used keypad library debouncing for reliable input. | ||
| + | |||
| + | Calibrated the weight sensor once for consistent measurements. | ||
