All the Arduino Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up their fundamentals on Arduino. Arduino is an open-source development platform that has both a programmable circuit board and software which runs on a computer, where code is uploaded to the board. Arduino IDE has a simplified version of the programming language C++, which is easier to program. The voltage required for Arduino models is between 6 and 12 volts. If the voltage is greater than 20 volts then the board will destroy due to overpowering. Arduino has several types of boards: Arduino Uno, Arduino Dieciimila, Arduino Due, Lilypad, Redboard, Arduino mega, and Arduino Leonardo. Arduino board has several pins 5v, 3.3v, TX, RX, Analog pins, digital pins, PWM, Analog reference, ground pins, reset button, voltage regulator, main IC, Microcontroller, and power LEDs. Arduino compatible boards use circuit boards called shields. Shields are used for controlling motors, ethernet, and Liquid crystal displays.
