1. Connect both servos’ red wires to the + 5V rail, and their brown wires to GND on the breadboard. 2. Connect one of the servo’s yellow signal wires directly to Arduino pin 9, and the other ...

The 5.2V is safe for all 5V-powered electronics like Arduino, Raspberry Pi, or Beagle Bone while preventing icky brown-outs during high current draw because of USB cable resistance. The VERTER has ...

This solar tracker system uses the Arduino UNO board ... the ones showned here at a slightly different angle. If your servo acts weird try to connect a 470µF/10V capacitor between the +5V and GND.
