In the previous tutorial we saw how you can drive the digital outputs of the Phidgets 1018
remotely, in this tutorial instead we will check the status of the digital inputs, which can be connected to magnetic contacts, push buttons, switches, etc.
You need:
a Raspberry Pi B or B+, with installed Web Server and the Phidgets library or you can use our Raspberry Pi – SBC, MODEL B+, 512M MicroSD 8GB Phidgets ready
a 1018_2 – PhidgetInterfaceKit 8/8/8
some switch
Connect the 1018 to a USB port on Raspberry and the switch to digital input and ground.
Step 1: The code
The code
Create a new folder that will contain all the files
Create a new file input.html
with this content
Create a new file input-emmeshop.js
with this content
Create a new file action.php
with this content
Make a link of domo-emmeshop from /home/pi/domo-emmeshop to /var/www/domo-emmeshop .
Finally, create a python file input-emmeshop.py
with this content
Step 2: How it work
How it work
The input.html file creates a web page based on HTML, jQuery and AJAX with 8 toggle switch that show digital inputs state.
When the page is loaded asks the status of the digital inputs at 1018 and displays it using the toggle switches
We have used a switch and a key switch, but you can connect magnetic contacts ( to see if doors and windows are closed ) or the Current Status Switch to see if an appliance is turned on ( I turned off the iron !!? )
