Be careful of short circuits!
short circuit:
direct connection between + and - sides of the battery
this means current is not forced to move through a component (like an LED)

Simple circuit challenges
Find an LED and a coin battery -- can you make a simple circuit?
Use an alligator clip to connect the positive (+) LED leg (longer) to the battery.
Use copper tape (and paper) to connect the negative (-) LED leg (shorter) to the battery.
CPX challenges
With the CPX unplugged from power, replace the coin batery of your circuit with the CPX by using alligator clips:
+ to 3.3V
- to GND
Check your circuit and then test it by plugging in the CPX.Create a circuit that uses capacitive touch (supported by the CPX) to turn the LED on.
Create a circuit that uses capacitive touch to turn a Neopixel strip on.
