- [Instructor] Now it's time to connect the Arduino development board and make sure we can upload a program. Before we do that, though, let's take a closer look at the board. The Arduino Nano 33 BLE Sense is packed with features, including a microphone, an inertial measurement unit and magnetometer, a humidity and temperature sensor, a barometric pressure sensor, a light sensor, and an RGB LED. The microcontroller on the board connects to all of these. The connections are called pins. Some of these pins connect to the pads on the edge of the development board, so they can be attached to external circuits. Other pins connect to onboard circuits, like the built-in LED or the microphone, and the pins have names used to refer to them in a program. Pins can be either input or output. As input, a pin might allow the microcontroller to get data from a sensor. As output, a pin might activate a motor or turn a light on or off. And finally, all of this hardware is controlled by a program…
