Key Features
- Explain the concept of Pulse Width Modulation (PWM)
- Assemble a basic circuit on a breadboard
- Program a Raspberry Pi Pico microcontroller
- Understand the relationship between duty cycle and LED brightness
- Analyze how PWM is used in everyday technology
Key Benefits
- Free, open lessons. The Learning MicroPython textbook has the kit page, wiring, and MicroPython code.
- Ready-made curriculum. 4 additional lab pages walk students through the build step by step.
- Classroom friendly. Built on a solderless breadboard or no-solder connectors.
- Try before you build. An interactive MicroSim on the kit page runs in the browser.
- Instant feedback. Students see their code's results on lights or a display.
- Budget. About $19 (sum of the listed parts: Pico $4, breadboard $1.75, potentiometer $0.50, LED $0.05, OLED $13).
