A-Star 32U4 Mini LV red light flashes and nothing happens

I can get the blink program to work fine but now nothing else, I get red and yellow light when i upload anything else. I had it working an then it stopped. any ideas on what the issue may may be.


Hello. John.

I am sorry you are having trouble programming your A-Star mini. The mini comes preloaded with the Arduino “Blink” sketch, so that sketch will run when the board is supplied with power. Can you try changing the delay values in the sketch to something else and uploading again to see if you can change the speed of the LED? If that does not work, can you tell me specifically what part of your attempt did not work? For example, did the code successfully compile? Does the A-Star mini show up in your device manager?
