Understanding the Basics
What is an Arduino?
Arduino is an open-source electronics platform based on easy-to-use hardware and software. It’s designed to make the process of using electronics in multidisciplinary projects more accessible. An Arduino board reads inputs, like the light on a sensor or a finger on a button, and turns it into an output, like activating a motor or turning on an LED. You can tell your board what to do by sending a set of instructions to the microcontroller on the board via the Arduino programming language and the associated Integrated Development Environment (IDE).
How does a Drone Work?
A drone, in the simplest terms, is an unmanned aerial vehicle (UAV). Drones are controlled either autonomously by onboard computers or remotely by a remote control. The key components that allow a drone to fly are its propellers, motors, and batteries, which work together to provide lift and control. The onboard sensors and microcontrollers regulate these components to maintain stability and control the drone’s flight path. Drones can be used for various purposes, including photography, delivery, and even recreational racing.
