Get Started with Electronics for Less Than $5 with Arduino!
Arduino is an open-source electronics prototyping platform that's suitable for beginners interested in learning electronics.
One of the most well known Arduino boards is the Uno model, which can be found in various versions but still does the same thing and runs the same code.
The mastermind of the Uno model is an ATmega328P or 168 logic chip that stores and runs your code.
The Uno model has 14 digital input/output pin sockets that can be configured to read or emit signals of zero or one (low or high).
The board also has five analog input pins that can work with sensors that have a variable voltage from 0-5V.
It's important to check whether your sensor is analog or digital before connecting it to the board.
The power pins on the board provide power to sensors and smaller output devices, but external power should be used for higher-powered motors or LEDs.
It's important to check whether your sensor is analog or digital before connecting it, and to use external power for higher-powered motors or a string of LEDs to avoid damaging your Arduino or computer's USB port.
Arduino is a fun and easy way to start learning electronics, and you can get started for less than $5 in hardware, making it accessible to anyone interested in tinkering with electronics.
