title: Send to Python script from PHP/JavaScript
body: <p>I'm working on a project where I send data to an Arduino from an Apache running on a Raspberry Pi.</p>
  
  <p>Sending data to the Arduino requires the Raspberry Pi to execute a Python script.</p>
  
  <p>The controls are detected and acted upon in JavaScript.</p>
  
  <p>I have found several ways to start the Python script from the JavaScript code. However, I can't find how I can then send data to the Python script from the JavaScript code so that the Python code can send data to the Arduino.</p>
  
  <p>Any help is appreciated!</p>
