Activity 2: Build and Test LED Indicator Lights

Indicator lights give people a way to see a representation of what’s going on inside a device, or patterns of communication between two devices.  Next, you will build indicator lights to display the communication signals that the Arduino will send to the servos.  If you haven’t ever built a circuit before, don’t worry, this activity shows you how.
