Ah yes, it is finally time to make your Arduino do something! We’re going to start with the classic hello world! of electronics, a blinking light. OK it doesn’t sound too exciting, heck you can just flip your desk lamp on and off without needing a microcontroller.. but I promise you, you’ll learn a lot!
This lesson will basically get you up and running using the Arduino software and uploading a sketch to the Arduino board. Once you’ve completed this step we can continue to the really exciting stuff, which is when we start writing our own sketches!
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.
