The SparkFun RedBoard Qwiic
The SparkFun RedBoard Qwiic is your development platform. At its roots, the RedBoard is essentially a small, portable computer, also known as a microcontroller. It is capable of taking inputs (such as the push of a button or a reading from a light sensor) and interpreting that information to control various outputs (like blinking an LED light or spinning an electric motor). That’s where the term “physical computing” comes in; this board is capable of taking the world of electronics and relating it to the physical world in a real and tangible way.
The SparkFun RedBoard is one of a multitude of development boards based on the ATmega328 microprocessor. It has 14 digital input/output pins (six of which can be PWM outputs), six analog inputs, a 16MHz crystal oscillator, a USB connection, a power jack, and a reset button. You’ll learn more about each of the RedBoard's features as you progress through this guide.
