the green LEDs seem dimmer than the others, and over time they have got dimmer. now the yellow LEDs are getting dimmer, and all the green and yellow ones flicker, the 2 flashing red LEDs on the hat have got brighter
I think I may have slightly damaged the capacitator under the battery by pulling out the lead slightly and could this be the fault, or could this be another problem. the battery hasnt been in long, but could a flat battery be causing this?

A flat battery will cause this behaviour. For best results, use a 12VDC adaptor.

I’ve just realised I’ve got 2 universal DC adaptors in my room, I should have tried those first
thanks :slight_smile:
