Simple lighting control

[tad.dvor]

Article describing simple lighting control with Arduino UNO, W5100 and MQTT.

1. What you need:

• Arduino UNO
• Arduino ethernet shield W5100
• Breadboard
• Jumper wires
• LED
• Button
• 10k resistor
• 200 ohm resistor
• PC (with Arduino IDE or Arduino Web Editor)
  (Instead LED can connect a relay to control light bulbs)

2. Ethernet shield W5100 plug into the Arduino UNO.
   Connect everything according to the diagram.
   

   

   It should look something like this.
   

   

3. Add a new device

• Add new …
• Device/Widget
• Bring Your Own Thing
• Enter your MQTT username, password and ClientID into your code
• Upload the code (In the code are written notes about each line.)

• Wait for the board to connect to Cayenne.
• After connecting to Cayenne, you should see this on the Cayenne Dashboard.

4. Adding button to control LED

• Add new …
• Device/Widget
• Custom Widgets
• Button

• Add Widget

If you did everything according to the article, it should work for you.
I hope you can help with your projects with Cayenne.

great tutorial @tad.dvor

[jerry]

Cant you just use add device to add the arduino than wait for the sketch to do it for you?

[bestes]

@jerry That’s one way to do it.

This tutorial looks a little different since it uses the Arduino MQTT library, which is something we’ll be switching to in the near future. Play around with it
