@dtex it's correct
Ah, okay. You need a special version of firmata and there are some other configuration issues. I haven’t used a NodeMCU, but the instructions should get you going: https://boneskull.com/how-to-use-an-esp8266-with-johnny-five/
The post you shared is for an Arduino Uno or Mega
@dtex I did follow but I did not see as a guide
@dtex now I want to turn on and off the led, DHT11 humidity sensor displays humidity temperature chart through nodejs sever.
the firmata chanes are excellent btw
let buttons = new five.Buttons([
{ pin: 3, isPullup: true },
{ pin: 5, isPullup: true },
{ pin: 8, isPullup: true },
{ pin: 10, isPullup: true }
]);
buttons.on("press", e => console.log(e.pin));
Buttons on pins 8 and 10 do nothing. Am I missing something obvious?
I'll also try the resistor. I thought that it wasn't needed when using the pull up resistors...
I should probably mention that I'm running this via NW.js. There might be something funky at that level. I don't know.

That could be it, but I still don’t quite see how. If it works on pins 3 and 5 I see no reason why that wouldn’t work on pins 8 and 10.
Sorry, not much help I know.
Hello, someone has already had experience with imu (for me the BNO055) and StandardFirmataWifi?
The onchange (..) and ondata (..) event we seem not to be triggered.
Is it a problem of timing?
I specify that my connection works well with the lib of adadafruit and the arduino ide by usb serial

By the way I'm using a esp8266
@dtex I'm following up on my problem from May 10. I tried your suggestions and they didn't work. However, I discovered that if I use an external powered USB2.0 hub to connect my Arduino clone, the problem goes away. I have no idea why. The port on my (old) computer is USB2.0. It is as though the hub provides more (or more regular) power to the Arduino. Ideas?
@nelsoniseru J5 is an API layer over firmata
Hi Guys!!
I try to manage 12 servos.
something like that:
var servos = new five.Servos([9, 10]);
servos[0].to(180)
servos[1].to(0)
servos[0].to(0)
servos[1].to(180)And it looks like something goes wrong, maybe i missed some lib or something like that?
Because it is doesn`t work asynchronous like in C !
Option 1:
const five = require("johnny-five");
const board = new five.Board();
board.on("ready", function() {
const servo = new five.Servos(9);
// Take 1000ms to move to 180
servo.to(180, 1000);
// Wait 1000ms and then move to 0
setTimeout(function() {
servo.to(0);
},1000)
});
Option 2:
var five = require("johnny-five");
var board = new five.Board();
board.on("ready", function() {
var servo = new five.Servo(9);
var animation = new five.Animation(servo);
// Create an animation segment object
animation.enqueue({
duration: 2000,
cuePoints: [0, 0.5, 1.0],
keyFrames: [ {degrees: 0}, {degrees: 180}, {degrees: 0}]
});
});
If I'm understanding correctly, johnny-five can utilize other third party npm packages correct?
i.e, I can do
npm install my-package and require that in my johnny-five script? What are the limitations here?
