I was testing my Arduino Uno R3 and uploaded blink file from examples and compiled and uploaded perfectly but nothing worked , please help ASAP .
What is your code? Is there an error message? We need this info to be able to help you. Otherwise you will not get any help!
no error message at all
And Code?
/*
Blink
Turns an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
the correct LED pin independent of which board is used.
If you want to know what pin the on-board LED is connected to on your Arduino
model, check the Technical Specs of your board at:

This example code is in the public domain.

*/
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
what do u think ??
I think. Have patience. You will get an answer!
Probably the pin is wrongly chosen.
ok I made 13 and not working as well

no its not solved as i say it does not blink at all
could it be the microcontroller ic but i reset it and the 13 button blinks then which means it works properly, so I have no clue whether it's the ic or something else on the Arduino chip.
Can you try it with this code?
void setup()
{
pinMode(13, OUTPUT);
}
void loop()
{
digitalWrite(13, HIGH);
delay(200);
digitalWrite(13, LOW);
delay(200);
}
compiled and uploaded but no blinking
connect an external LED with resistor to port 13.
i tried now it blinks when code uploaded but then it went off
what should i do , can u explain more please
Post a picture of the Arduino hardware.
I found this tutorial:
It's the same code but the schematic isn't the same:
