Hi, I’ll post some pictures of my setup. It worked fine until an hour ago then it just stopped. The supply will still power the motor and the d1 will still work powered via usb. I tried changing wires, changing wires around, etc. The leds on the d1 and the power supply both go on for a split second when I push the button, then go off. Any ideas? Thank you.
Have you tried a fresh battery? 9V batteries don't have much capacity.
