The Potentiometer and PWM LED page shows how to read a potentiometer and use PWM to fade an LED using your Pico and CircuitPython. It includes wiring diagrams to show you how to connect everything up. There are explanations of code, as well as analogue signals, analogue-t0-digital converters, pulse-width modulation and more!
The Data Logger page shows you how to turn your Pico into a temperature data logger using its internal temperature sensor. There are two ways to do it, one requiring a breadboard, and the other not. The idea is that if you use a USB battery pack, you can make the data logger stand alone and take it anywhere with you!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
