FAQs on Arduino Tutorial #1 - Digital Inputs and Outputs - Button & LED Video Lecture - Drones for Beginners: How to make Arduino Drones - Electronics and Communication Engineering (ECE)

1. What is Arduino?
Ans. Arduino is an open-source electronics platform based on easy-to-use hardware and software. It consists of a physical programmable circuit board (often referred to as a microcontroller) and a development environment that allows users to write and upload computer code to the board.
2. What is a digital input?
Ans. A digital input is a type of input pin on an Arduino board that can detect and read the state of a digital signal. It can be set to either HIGH (1) or LOW (0), depending on the voltage level received from an external device or sensor.
3. What is a digital output?
Ans. A digital output is a type of output pin on an Arduino board that can send a digital signal to control external devices like LEDs, motors, or relays. It can be set to either HIGH (1) or LOW (0) to turn the connected device on or off.
4. How can I connect a button to an Arduino?
Ans. To connect a button to an Arduino, you would typically connect one leg of the button to a digital input pin on the Arduino and the other leg to either the ground (GND) or the 5V power supply. You would also need to add a pull-down or pull-up resistor to ensure reliable button readings.
5. How can I control an LED using Arduino?
Ans. To control an LED using Arduino, you would connect one leg of the LED to a digital output pin on the Arduino and the other leg to a current-limiting resistor and then to either the ground (GND) or the 5V power supply. By setting the digital output pin to HIGH or LOW, you can turn the LED on or off, respectively.
