- Compile and upload the Firmware to your MegaPi ( https://github.com/Makeblock-Official/FirmwareForMegaPi )
- On your Raspberry Pi,
npm install megapi
- Insert the initial code for starting MegaPi first.
var MegaPi = require("megapi").MegaPi;
var bot = new MegaPi("/dev/ttyAMA0", onStart); //"/dev/ttyAMA0" for rpi2, "/dev/ttyAMA0" for rpi3
function onStart(){
//start your code
setTimeout(loop,500);
}
var level = 0;
function loop(){
bot.digitalWrite(13, level);
level = 1-level;
setTimeout(loop,500);
}
- node your code
