Transistors

Start with two PN2222 transistors. Bend the emitter legs outward, away from the other legs, as shown.
Twist the base legs of both transistors together. Repeat with the collector legs.
Insert the twisted legs of the transistors into holes in the Flora board. The center (base) legs of the transistor should go in the hole marked SCL. The twisted collector legs should go in the hole marked GND (ground). The non-twisted emitter legs of the transistor should stick out as shown, following the edge of the Flora board.
Solder the transistor wires to the pads of the Flora.
Use flush snips to clip off the excess wire on the other side of the board. The other transistor legs will be attached to the IR LEDs later.
