 1. Plug in your ESP32 and flash it with the starter code
 1. Open the serial monitor
 1. You should see your controller address as a string of octets (something like `98:B6:E1:7C:C3:95`) in the serial monitor while trying to connect your controller (press and hold power button on controller until lights slowly and then rapidly move to put it in pairing mode):

 # Line Sensor
 A necessary component for any challenge that requires your robot to follow a line. This one is the QTR-8A Reflectance Sensor Array and uses IR transmitters and receivers on it to detect lines.

 ## How it Works
 The line sensor is made up of an array of 8 IR LED/phototransistor pairs, each take an analog reflectance reading by timing how long it takes the output voltage to decay due to the phototransistor. By pointing the line sensor IR LEDs/phototransistors at the line, the robot is able to tell where the dark line of tape is by reading the output voltage of each phototransistor
 
 This side of the sensor will be facing the floor to detect the line:

 {: .highlight}
-You do NOT have to use all 8 of the LED/phototransistor pairs — You can leave the ones you do not want to use disconnected from the ESP32.
+Keep in mind that the QTR line sensor has two 5V pins that are connected to each other! They are identical in function besides being in a different location

+TODO decide if we want to make them use the LEDON pin
+TODO add backside pinout with labels
