How To Reset Arduino || How To Delet old code From Arduino | easy way ||
To reset an Arduino, you can follow these steps:
Press and hold the reset button on the Arduino board. The reset button is usually located near the USB port.
While holding down the reset button, disconnect and then reconnect the USB cable from the Arduino board.
Release the reset button.
Alternatively, you can use the Serial Monitor in the Arduino IDE to reset the board:
Open the Arduino IDE and select the appropriate board and port in the Tools menu.
Open the Serial Monitor by clicking on the magnifying glass icon in the upper right corner of the IDE.
In the Serial Monitor, click on the "Send" button to send a blank line to the board.
The board will reset and the Serial Monitor will display the startup message.

Arduino Blinking
ARDUINO BLINKING
Arduino Blinking is a basic project in which an LED connected to an Arduino board is made to blink on and off repeatedly. This project is a great way to get started with Arduino programming, and it can be used as a building block for more complex projects.
To create an Arduino Blinking project, you will need the following:
▪︎An Arduino board (such as an Uno or Nano)
▪︎A breadboard
▪︎An LEDA 220-ohm resistor
▪︎Jumper wires
Follow these steps to create an Arduino Blinking project:
Connect the LED to the breadboard. Place the long leg of the LED in a hole connected to a positive rail on the breadboard, and place the short leg in a hole connected to a negative rail on the breadboard.
Connect the 220-ohm resistor to the LED. Place one end of the resistor in the same row as the short leg of the LED, and the other end in a hole connected to a negative rail on the breadboard.
Connect the resistor to the Arduino board. Use a jumper wire to connect the end of the resistor that is in the same row as the LED to a digital pin on the Arduino board. In this example, we will use digital pin 13.
Connect the negative rail of the breadboard to the ground pin on the Arduino board using a jumper wire.
Connect the positive rail of the breadboard to the 5V pin on the Arduino board using a jumper wire.
Upload the following code to the Arduino board using the Arduino IDE:
code
void setup() {
pinMode(13, OUTPUT);
}
void loop() {
digitalWrite(13, HIGH);
delay(1000);
digitalWrite(13, LOW);
delay(1000); }
Power on the Arduino board. The LED should start blinking on and off every second.
This code sets up digital pin 13 as an output, and then uses the digitalWrite() function to turn the LED on and off every second using the HIGH and LOW parameters. The delay() function is used to pause the program for one second between each blink.
Congratulations, you have created an Arduino Blinking project!
