2. Explore the Board

2.1. Insert the AAA battery into the battery holder on the back of the board.
2.2. Remove the jumper from J2 (back of board, left side, center).
2.3. Slide your finger across the slider. Notice how the LEDs illuminate in a clockwise direction 

as you move your finger from the left to the right across the slider.

2.4. Press the mechanical button at the bottom of the board. All four LEDs light up.
2.5. Turn the board off by replacing the jumper on J2. Note that replacing the jumper disables 

battery operation.

Caution: Do not touch the board anywhere other than the edges or the
buttons.

 Touching the board in the wrong area could lead to a short and an

unresponsive board. If this happens, follow the instructions in Section 2 to
reset the power to the board.
