🔆 Tutorial 12: Using Digital and Analog Sensors to build a motion sensing auto dimming nightlight
In this episode of our Object-Oriented Programming with MicroPython tutorial series for the Raspberry Pi Pico, we explore *digital and analog sensors* and how to integrate them into real-world IoT applications.
We build a *sensor-controlled light system* that combines:
💡 A *PIR motion sensor* to detect movement and activate the light
🌞 An *LDR (Light Dependent Resistor)* sensor to adjust the brightness automatically based on ambient light
Through this project, you’ll learn how to:
Design classes for digital and analog sensor input
Incorporate sensor data into an object-oriented MicroPython application
Use inheritance and composition to extend functionality
Simulate and test the system before implementing it on real hardware
This episode demonstrates how *object-oriented design principles* make embedded development modular, reusable, and scalable — even for small microcontrollers like the Raspberry Pi Pico.
