Node For ZeroPi

• prepare your ZeroPi board. ( install the Firmware: https://github.com/ZeroPiProject/ZeroPi_Firmware )
• git clone https://github.com/ZeroPiProject/NodeForZeroPi on your Raspberry Pi
• Install using npm, npm install serialport@2.0.0
• Enter the folder "NodeForZeroPi", and sudo node digitalWrite.js

Example

var ZeroPi = require("zeropi").ZeroPi;
var bot = new ZeroPi(onStart);
var level = 1;
function loop(){
  bot.digitalWrite(13,level);
  level = 1-level;
}
function onStart(){
  setInterval(loop,100);
}
