Description
A smart basketball hoop built on a Raspberry Pi Pico 2W, using the Rust programming language and Embassy async framework.
Features:
- Ball trajectory detection using 3 ultrasonic sensors
- Real-time shot quality feedback with RGB LEDs
- Score counter on a 7-digit display
Motivation
As a sports enthusiast and basketball fan, I wanted to create a project that helps players improve their shooting accuracy. This smart system provides instant, data-driven feedback to optimize performance during training.
Architecture
Processing Unit: the Raspberry Pi Pico 2W interprets sensor data, decides on shot accuracy, updates score, and controls visual feedback.
Feedback Layer: includes the RGB LEDs and the 7-digit display to provide immediate, local feedback.
Communication Layer: the built-in Wi-Fi module transmits shot statistics to an external device for visualization or analysis.
Data Acquisition Layer: composed of ultrasonic sensors, which collect real-time data after each shot.
Flow Summary:
After a shoot, the sensors will send the data via WIFI to PC for processing. If the ball goes through the hoop, the score increases on the display. Based on the shoot, the RGB LEDs will show one of the color:
- green for a perfect one
- yellow for a good one
- red for a fail

Hardware
The Raspberry Pi Pico 2W serves as the core controller, interfacing with the sensors and peripherals.
- IOE-SR05 Ultrasonic sensors : measure the distance between the ball and the rim to analyze the trajectory.
- RGB LEDs : light up based on shot accuracy (e.g., green for perfect, red for miss).
- 7-digits display : increments the score when a basket is made.
- Wireless module(built-in): sends data to a PC or mobile device for further analysis.
