Let’s program the Arduino with JavascriptšŸ¤Æ




Have you ever ever programmed an Arduino? Do you know that Arduino may be programmed with JavaScript?šŸ˜

Necessities

  • Arduino UNO microcontroller,
  • LED,
  • 220-ohm resistor,
  • Arduino IDE put in,
  • NodeJS put in (I like to recommend the newest LTS model),
  • Visible Studio Code (or one other code editor).

We should first assemble the circuit we’re going to work with.

A circuit much like that is created in TinkerCad.

As soon as we now have the circuit assembled we have to put together our Arduino for programming with JavaScript not but fully.

We should first set up the Firmata library on it.

Navigate to File> Examples> Firmata> StandardFirmataPlus and add the file that opens to our Arduino.

Where can find Firmata Library in Arduino IDE

Add the code to the Arduino board by urgent the Add.

After a profitable add, we have to set up some pre-required instruments.

Now’s the time to make a listing the place we are going to write our code for Arduino.

Since I am utilizing a Home windows laptop, I needed to do a few issues earlier than I may begin programming Arduino with JavaScript.

Within the console with administrative privileges, enter two instructions to put in two extra applications.

npm --add-python-to-path set up --global --production windows-build-tools
Enter fullscreen mode

Exit fullscreen mode

and set up the node-gyp JavaScript library with the command

npm set up -g node-gyp
Enter fullscreen mode

Exit fullscreen mode

To your working system, test what you want to set up earlier than beginning at this link.

After putting in all the things you want, we will begin working.

We’ll use the johnny-five library to program the Arduino, which is without doubt one of the higher libraries for programming microcontrollers. It helps Arduino, Raspberry Pi and extra … An inventory of all is offered at this link.

The library permits us to program many parts for the Arduino. The benefit I see is that it makes many duties simpler for us in comparison with C ++.

Code for our easy circuit.

const {Board, Led} = require("johnny-five");
const board = new Board({
    port: "COM3" // Examine if is your Arduino on this port (this you may make in Arduino IDE)
});

board.on("prepared", () => {
  const led = new Led(3);
  led.blink(500);
});
Enter fullscreen mode

Exit fullscreen mode

Now, all we now have to do is run this system on our Arduino. To do that, kind within the command line:

node major.js # In case if our file is known as major.js
Enter fullscreen mode

Exit fullscreen mode

Now it is your flip to begin creating quite a lot of circuits with JavaScript and the Arduino microcontroller.
