This code is used to blink the LED connected at pin-13 of Arduino UNO and produce buzzer beeps alternately. First type the code by creating new file in Arduino IDEWhat is Arduino IDE? Arduino IDE stands for Integrated Development Environment. It is also called as Arduino software in general language or Arduino compiler. It is used to convert high level programming language like C/C++ program into machine code i.e. into low level language., save the file and then upload it.

Required Material
Arduino UNO Board – 1, data cable – 1, Red LED – 1, Resistor 1kΩ (Brown Black Red) – 1, Buzzer – 1, Jumper wires - 4.
Working
After uploading the code in Arduino UNO board, the buzzer and LED “L” will be ON alternately. This happens because of alternate action written in the code.
The Code
Upload the following code in Arduino UNO to control LED and buzzer in alternate action. It is very interesting code, which will help you understand the simple logic behind controlling number of devices using Arduino.
