My first post hope this help someone.
I played arduino with matrix display text scrolling and someway on road
arduino stopped working and didn't accept new program not even simple blinkled
After searching google for avrdude error.none of them work becouse reprogramming was impossible i thought i bricked it.
SOLUTION
i use this simple default sketch
void setup() {
// put your setup code here, to run once:
}
void loop() {
// put your main code here, to run repeatedly:
}
Disconnected arduino from usb. connect it back and same time hit SEND program
This worked. it had time send new small empty sketch before start blink rapidly ![]()
i think i had some error on last program and it prevent it to make connect to IDE
