Arduino
Arduino is a world famous open-source hardware/ software platform. Arduino was created in 2005 by a research team at the Interaction Design Institute Ivrea in Italy, with the aim of making physical computing devices that connect sensors, actuators and other components easier, cheaper, and more popular to build. The major components of Arduino and their uses. Component - Uses Microcontroller Chip (ATnega328P) - This part is called the brain of Arduino. It collects information and controls the devices according to the instructions. DIGITAL I/O PINs - Collects data from input devices. Controls output devices. The pins marked with tilde (~) symbol can also be used for Pulse Width Modulation (PWM). USB Port - For connecting to computer to upload programs and transfer data. External Power Supply - For supplying power to the board from the battery or other external source. 5V PIN - This provides a steady 5V. 3.3V PIN - This provides a steady 3.3V. GND - This provides the ground potentia...
