Servo on esp8266

[portedison]

Hey cpopp, I'm trying to built this arm, using an esp8266, and mg995 servos, But having an issue with servos not responding, only ticking. This is the first time I've tried to use the mg995 on the chip, did you need to use a capacitor, or an external power supply for the servos? If I introduce a new power supply and connect vcc + grd to the battery, I lose everything. Any tips? Sometimes if I move in 2deg increments it tracks along... all that said the servos are from AliExpress, and may be crap.?

Ha, maybe the servos are crap, just typed rotate.write_angle(22) and it did a continuous rotation. I couldn't do anything to exit it. Damn.
