The image in the Project Essentials Guide shows some LEDs that have clear, red, and green colored plastic caps. The NI myRIO Starter Kit contains many colors of LEDs but they all have clear plastic caps.
The schematic shown in the document shows a 220 Ohm resistor as an example for the series resistor necessary in an LED circuit. The kit does not have a 220 Ohm resistor. When working with this chapter you can use two 100 Ohms in series or two 470 Ohm resistors in parallel.
