Pico: drive a 28BYJ-48 stepper motor with a ULN2003 driver
Wire a 28BYJ-48 stepper to a Raspberry Pi Pico with the ULN2003 board and drive it with MicroPython. Precise position control for about $3 in parts.
Pico W: set a static IP for a reliable local device
Give a Pico W a fixed IP address with MicroPython so bookmarks, port forwards, and automations keep working after the router reboots.
Pico: PWM in depth with MicroPython, frequencies and duty cycles
Use the Pico's 8 PWM slices from MicroPython to drive servos, dim LEDs, generate tones, and synthesize analog output with a low-pass filter.
Pico W: async web server with uasyncio, the modern pattern
Serve a real async web API from a Pico W using uasyncio, with background sensor tasks and non-blocking request handlers. The right way after the synchronous server gets too small.
Pico W: Bluetooth Low Energy peripheral with MicroPython and aioble
Turn a Pico W into a BLE peripheral that a phone can connect to over Bluetooth Low Energy, with a GATT service, read, write, and notify characteristics.
Pico W: publish MQTT messages from MicroPython over Wi-Fi
Connect a Pico W to Wi-Fi and publish sensor readings to an MQTT broker from MicroPython. The pico equivalent of the ESP32 MQTT tutorial.
Pico W: serve a live sensor dashboard over Wi-Fi
Read a DHT22 or BME280 and serve a live dashboard from a Pico W. The smallest, cheapest way to put a sensor reading on your phone's browser.
Pico: blink the onboard LED with MicroPython (the 5-minute start)
The shortest possible Pico + MicroPython tutorial. Blink the LED. Get to a working project before you know all the theory.
Pico: drive a servo motor with MicroPython
Control a hobby servo from a Pico using PWM and MicroPython. Includes the library code I use in every Pico servo project.
Pico: read a DHT22 with MicroPython
Wire a DHT22 temperature and humidity sensor to a Pico and read it from MicroPython. The smallest useful Pico sensor project.
Pico W: serve a web page from the chip over Wi-Fi
Connect the Pico W to Wi-Fi and serve an HTML page from the chip. The smallest useful web server on a $6 microcontroller.
Pico: get started with MicroPython on the Raspberry Pi Pico
Flash MicroPython to a Raspberry Pi Pico, connect over the REPL, and run your first script. The 10-minute Pico setup.
