Hi Arduino Forum,
This is my first post, thank you in advance for your help and patience.
Project: Miniature amusement park model
Board: Pro Trinket 5V 16mhz
Animation: 6 LED lights (in two groups of 3)
Power: A 12V bus, which powers the lights, Pro Trinket, and other elements of the model (motors)
Problem: Pro Trinket will only run the sketch when the micro USB is plugged in.
When powered through Bat + or VBat, the LED lights turn on, but there is no animation or program running.
I have tried both options of reprogramming the bootloader without any change.
