Description
Take test board, desolder one green LED, replace with IR LED and put in series with Ammeter, and plug into robot board. Document current read by Ammeter with an IR LED and with a green LED. Draw conclusions about what the current through BOM LEDs are. Document findings.

- Status changed from New to 5
Current for Green LED: 21.78 mA
Current for IR LED: 21.78 mA
Both LEDs run on the same current. Now we can move on and design a circuit that regulates the current to around 21.78 mA to mimic the behavior of the robot.
