LED on Arduino does not blink

Question

I successful installed arduino, added me to uucp and lock and loaded cdc_acm module.

I use Arduino Uno R3, so I also installed arduino-avr-core.

I have Arduino on /dev/ttyUSB0.

I configured with:

stty -F /dev/ttyUSB0 cs8 9600 ignbrk -brkint -imaxbel -opost -onlcr -isig -icanon -iexten -echo -echoe -echok -echoctl -echoke noflsh -ixon -crtscts

I have this folder with these files: ~/Documents/Arduino

build.options.json
------------------------------------------------------------
{
 "fqbn": "archlinux-arduino:avr:uno",
 "hardwareFolders": "/usr/share/arduino/hardware",
 "toolsFolders": "/usr/bin"
}
sketch.ino
------------------------------------------------------------
void setup() {
 pinMode(13, OUTPUT);
}
void loop() {
 digitalWrite(13, HIGH);
 delay(1000);
 digitalWrite(13, LOW);
 delay(1000);
}

After this commands I got output:

arduino-builder -build-options-file build.options.json sketch.ino
Sketch uses 914 bytes (2%) of program storage space. Maximum is 32256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

But nothing happened on my Arduino, what's my problem?

Thanks.

P.S. I don't have external LED, I try to use bultin LED.

• Juraj: did you try Arduino IDE?
• J. Doe: I don't wanna use Arduino IDE. And when I tried it, I got error with avrdude.
• Juraj: there is no way around avrdude

Answer 1

You invoked the builder, but not an upload to the board. The builder created a hex file.You should use avrdude for upload.

Or use Arduino IDE which does it with a click on a button

• J. Doe: I don't have hex file. I try to search, but I cannot find it.
• Juraj: turn on verbose output of the builder
