Simple interface example with arduino

In this post we'll explain how to interface and access an arduino project over the internet or by LAN. In the following screenshot I'll display some actions that my arduino does.

For example, the sketch print MotionDetected to the serial port when PIR sensor detect motion, take illumination conditions on light command, read RF data from a remote control in order to transmit back to the corresponding device, and display the temperature when temp command is called.

Let's make a simple paradigm with temp.

So, when temp command is sent to the serial monitor arduino returns the current temperature (1st screenshot). To create an interface, go to Control Panel/Instruction Sets/Add New Launcher. Enter a name (handler) and judo serial send <command> API call to transmit temp command to the serial port.

To make this action available to the dashboard, go to Control Panel/Instruction Sets/Add New Instruction Set and follow the screenshot.

We always put the asterisk (*) token before a launcher to invoke it and retrieve the return value. In this case temp should be described as *temp. Save the above example, go to the Dashboard, refresh the page and you'll see the new command we just create.

This is the result when it clicked. It will replace the *temp action with the value that arduino returns.

For further debugging, launchers and instruction sets can be tested via terminal tab.

 

In the same way we can make our security triggers, control appliances remotely, etc. More examples will follow.
