Now that we have our analog data being read through Node.js, it's time light some LEDs! Before we begin, we need to physically connect the LEDs using the Clock (pin 13) and Data (pin 11) inputs on the Galileo. As with most sensors, the LED strip needs to be connected to ground and a power source. In order to program the strip, we use the CI and DI wires, between the GND and 5V inputs.
- Connect cables to strip
Start by connecting a female/female cable to the LED strip
- Connect jumper to cable on strip
Using the male/male cables, plug in a wire to each female input
- Connect GND and PWR
Connect the GND cable to the breadboards GND (blue) strip. Then, connect the PWR cable from the LEDs to the breadboards PWR (red) strip.
- Connect clock and data wires
Connect the Clock In (13) and Data In (11) pins on the Galileo. Be sure to connect the correct wires from the strip to the Galileo.
LED strip DI > pin 11
LED strip CI > pin 13
