This code is used to blink the LED connected at pin-13 (LED_BUILTIN). This LED is marked as “L” on the Arduino UNO board. First type the code by creating new file in Arduino IDE, save the file and then upload it.
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 IDE, save the file and then upload it.
This code is used count the number of objects passing in front of the IR sensor. It displays the count of the object on serial monitor in Arduino IDE software.
In this code when the button is pressed, the servo motor starts rotating smoothly from 0 – 90 and then 90 – 0. When the button is released, the motor restores back to angle 0.
In this code the LED display shows counting from 9 – 0. When 0 appears on the display it produces buzzer sound. The pin configuration of LED display and connection diagram is given below.
