+For this competition, you will be able to control your robot with a wireless game controller.

+It would be impractical to power your ESP32 through your laptop with a super long cable, so you will use a battery pack feeding through a buck converter to power the 5V pin of the ESP32.

+
+You will use this buck converter to reduce the voltage of the battery pack down to a level the ESP32 can tolerate (5V). Here are the steps to interface the battery pack to the ESP32 (assumes ESP32 is seated in breadboard):
+
+ 1.) Connect the red wire from the battery pack to the IN+ on the buck converter and the black wire from the battery pack to the IN- on the buck converter
+
+ 2.) Grab a multimeter, put it into voltage reading mode, and attach the leads to OUT+ and OUT-. Rotate the small yellow screw on the buck converter counterclockwise until the multimeter reads a voltage of 5V.
+
+ 3.) Remove the multimeter leads and attach a red wire from the buck converter's OUT+ terminal to the ESP32's 5V pin. Attach a black wire from the buck converter's OUT- terminal to the ESP32's GND pin.

 ## What Are Servos?
 
-Servos are motors that are designed for precise position control. Instead of rotating arbitrarily when powered, servos listen to a control signal (usually [PWM](https://learn.sparkfun.com/tutorials/pulse-width-modulation/all)) to determine where to rotate. Some servos offer limited rotation, while others can rotate continuously (like ours).More advanced servos have other ways to be even more precise such as a feedback system on top of the control signal, but that is not necessary for this competition.
