This project demonstrates how to integrate the Raspberry Pi Pico with a Cricket WiFi module to enable WiFi connectivity and send notifications to a mobile device. It highlights the power efficiency of the Cricket module, allowing devices to operate on batteries for extended periods.
Designed for individuals with basic IT skills, this tutorial provides step-by-step instructions for building a complete, functional device. The core of the project involves a simple Python program that triggers a notification every five minutes.
The tutorial utilizes the Blynk mobile application for receiving notifications, chosen for its user-friendly interface. However, the Cricket module's compatibility with protocols like MQTT and HTTP(S) allows integration with various other internet services and local network systems.
This project serves as a foundation for building diverse IoT devices, from sensor-based systems to more complex applications involving local processing and machine learning. The Raspberry Pi Pico is presented as an excellent platform for rapid prototyping.
