A Node.js Library to Interact with Blinkt
npm install node-blinktvar Blinkt = require('node-blinkt'),
leds = new Blinkt();
leds.setup();
leds.clearAll();
leds.setAllPixels(0, 156, 0, 0.1);
leds.sendUpdate();Connects to the GPIO and sets the GPIO pin modes. Must be called before any other commands.
Connects to an alternative set of GPIO pins and sets their modes. Can be called instead of the setup() function if you have wired blinkt up to alternative raspberry pi pins. The default values are 23 and 24 respectively.
Clears the pixel buffer. This is the same as setting all pixels to black. You must also call sendUpdate() if you want to turn Blinkt! off.
Sets the specififed pixel to the passed rgb and brightness level. The pixelNum is an integer between 0 and 7 to indicate the pixel to change.
Sets the brightness level between 0.0 (off) and 1.0 (full brightness) for the specified pixelNum. The pixelNum is an integer between 0 and 7 to indicate the pixel to change.
Sets all pixels to the passed rgb and brightness level.
This method is the most important. You can set pixels colours as much as you want but they will not update until you call this method.
IoT.js is an alternate JavaScript runtime powered by JerryScript engine targeting more constrained devices.
