I have 4 heavy duties servos, 1 HD, and 1 micro servo attached to EZB. And a bunch of LEDs, HBRIDGE, etc all but 1 addressable port is available.
Today I noticed one of my servos was failing. In fact, it smelled like plastic was burning. But it wasn't the servo itself but the plastic female pin connectors. The Red and Black ones melted together. Both at the EZB side and at the servo end.
1. What can cause this, and how can I avoid this?
2. Is there a way I check through the terminal if D16 is still functioning?
3. I'm using the orange DFRobot labeled 2200mAh 7.4v battery but when I working with the servos the battery drains in a minute getting the "battery is low" message. Am I doing something inherently incorrect or is my battery just not enough to power everything?
