1 Red, 1 Green, and 1 Amber LED
1 10K Ohm resistor
1 Photo cell

Resistor
Photo cell
First, make sure the screws in the terminal block are set to the open position (this should
be the ‘factory default’). Like a standard screw, clockwise tightens and counter-clockwise
loosens the connector terminals.
We’ll use the pins on the left hand side of the Proto Board to connect the LEDS. We’ll
also use the pins in the lower right hand corner of the Proto Board (GPIO11-12 and
GND) to attach the photo-cell and the 10K resistor pull-up resistor for this demonstration.
Note: Resistors have color bands on them that indicate how much resistance
they provide. But rather than providing a lesson in color bands, we have
provided resistors with different body colors, too. The 10K Ohm part is beige
in color, while the 100K Ohm resistor is blue. We’ll use the beige resistor for
this demonstration .
GOAL: To demonstrate how information gathered from sensors onboard a SNAP node
can be communicated to other nodes and used to initiate other tasks
Step 1 – Disconnect the power running to the Proto Board.
Step 2 – Determining LED polarity:
Find the green LED. LEDs do have a polarity, meaning they can only be connected in
one way, so we’ll need to determine which end is the negative terminal (a.k.a the
cathode). One of the legs of the LED should be shorter than the other. This is the
“negative” leg. A flat spot on the rim at the base of the colored bulb also indicates which
side is the negative. The following picture should help:
