Arduino UNO "An unexpected error occurred while writing flash"

Arkadaşlar Arduino UNO ile kod yüklerken şu hata ile karşılaştım:

[ERROR] Stk500: receive() timeout
[ERROR] Stk500: paged_write(): (a) no response
[ERROR] AvrUploader: paged write failed (0)
[ERROR] UploadService: Upload error: An unexpected error occurred while writing flash.
An unexpected error occurred while writing flash.

name.antonsmirnov.android.uploader.UploadService$a.run(UploadService.java:9)
Error: An unexpected error occurred while writing flash.
Consider switching to Avrdude uploader (⋮ / Settings / App settings / Uploader) or follow troubleshooting (⋮ / Help / Troubleshooting)



Bu arada arduinodroid ile yüklüyordum, yardım edin.

Kodum şu:
void setup() {
pinMode(11,OUTPUT);
}

void loop() {
digitalWrite(11,HIGH);
delay(500);
digitalWrite(11,LOW);
delay(500);
}
