EXPANDED TECHNICAL DETAILS
Interactive UI/UX Emulation
This project simulates a modern smartphone incoming call interface on a large 3.5" TFT display, ideal for social pranks or theatrical props.
- High-Resolution Graphics Rendering: The Arduino uses the ILI9486 driver over an 8-bit or 16-bit parallel bus. The firmware renders custom bitmaps for the "Accept" and "Decline" buttons with smooth color gradients.
- Ringtone Audio Synthesis: Simultaneously plays a polyphonic ringtone via a piezo speaker or the
tone()function, perfectly synchronized with the flashing "Calling" animation on the screen.
Performance
- Touch-Matrix Calibration: Uses the resistive touch layer of the TFT. The Arduino detects the "Swipe to Answer" gesture, transitioning the UI to a "Call in Progress" screen with an active timer.
