Description
The Smart Desk Assistant shows notifications pulled from a server. Users can scroll through them, delete them, and get buzzer alerts for timer-based reminders.
Motivation
I wanted a simple and useful device to help manage my tasks without being distracted by my laptop or phone. Also, seems like a good project to practice networking in embedded programming.
Architecture
Main components:
- Server: Hosts the notifications and sends them on request.
- Raspberry Pi Pico W 2: Connects to the server over WiFi, manages notifications, updates the display, and handles button inputs.
- OLED Display (SSD1306 I2C): Displays the notifications.
- Buttons: Navigate through and delete notifications.
- Buzzer: Alerts when timer notifications trigger.
Connections:
- WiFi connects the Pico W 2 to the Server.
- I2C connects Pico W 2 to the OLED Display.
- GPIOs connect Pico W 2 to the Buttons and Buzzer.
