When you learn programming you usually start with a simple Hello World program that prints a message to the screen. Hello World helps you get started by learning the basics of typing in and running code that does something interesting like print to the screen. For hardware projects instead of printing to a screen the simplest Hello World is blinking a LED on and off. If you can blink a LED then you can control the pins on a board, and once you have control of the board there’s almost no limit to what you can do!
This guide walks through how to use MicroPython to blink a LED. You’ll learn how to connect a LED to a board and what MicroPython code to run to make it blink. As you walk through this guide you’ll learn the basics of running MicroPython code and controlling hardware.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
