# LED control with Arduino, Beebotte

> This tutorial presents how Beebotte can be used to control a led connected to an Arduino board.

Original author: beebotte (source: https://beebotte.com/tutorials/led_control)

## Components

- **Arduino UNO** x 1 ([docs](https://www.farnell.com/datasheets/1682209.pdf))
- **Arduino Ethernet Shield** x 1 ([docs](https://docs.arduino.cc/retired/shields/arduino-ethernet-shield-without-poe-module))
- Software: **Arduino IDE** ([docs](https://www.arduino.cc/en/software))
- Software: **beebotte**

## Article

### **Required Hardware**

We need the following hardware in order to complete this tutorial:

- Arduino UNO board or equivalent

- Arduino Ethernet Shield to connect to the Internet

- Breadboard (tiny one is enough)

- LED

- 220 Ω resistance

- Jumper wires

### **Subscribing to led control messages**

Include dependencies:

```c
#include <SPI.h>
#include <Ethernet.h>
#include <PubSubClient.h>
#include <ArduinoJson.h>
```

### **Creating a Dashboard with a control widget**

In your account page, go to `My Dashboards` and click `Create Dashboard`; enter a friendly name and a short description for your dashboard then add an `ON/OFF` Widget. Indicate the channel and resource you want to control with this widget. Voilà.
