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. You can program it to accept inputs such as the push of a button or a reading from a light sensor and interpret that information to control various outputs like blinking a light like an LED or spinning an electric motor. That’s where the term “physical computing” comes in; this board can take the world of electronics and relate it to the physical world in a real and tangible way.
The SparkFun RedBoard Qwiic 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 pulse-width modulation outputs; also referred to as PWM), six analog inputs, a 16MHz crystal oscillator, a USB connection, a power jack, a reset button and a Qwiic connector for connecting other Qwiic devices. You’ll learn more about each of these features as you progress through this guide.
