Code

Photon 2 Side Code

C/C++
This is the code in the Photon 2 for this project. It reads the input from the motion sensor, and once motion is sensed, it sends a webhook request.
#include "Particle.h"

int motionSensor = 6;
int lastMotionState = LOW;

void setup()
{
	pinMode(motionSensor, INPUT);
	Serial.begin(9600);
}

void loop()
{

	int motionState = digitalRead(motionSensor);
	

	if (motionState == HIGH && lastMotionState == LOW)
	{
	    Particle.publish("switchTabs1");
	    Serial.println("Motion sensed");

	}
	
	lastMotionState = motionState;
	

}

Computer Side Code

JavaScript
This is the code that, once my computer receives the webhook, triggers the AutoHotkey script
const { exec } = require("child_process");
const express = require("express");
const bodyParser = require("body-parser");

const app = express();
app.use(bodyParser.json());

// Webhook endpoint
app.post("/motion", (req, res) => {
    console.log("Webhook received:", req.body);

    console.log("Launching AHK script...");

    // Run AutoHotkey Script + error feedback
    exec('"C:\\Program Files\\AutoHotkey\\v2\\AutoHotkey.exe" "C:\\scripts\\switchTabs.ahk"', 
    (error, stdout, stderr) => {
        if (error) console.error("Error running AHK:", error);
        if (stderr) console.error("AHK stderr:", stderr);
        if (stdout) console.log("AHK stdout:", stdout);
        else console.log("AHK script executed (no stdout).");
    });


    res.send("OK");
});

// Start server
const PORT = 3000;
app.listen(PORT, () => console.log(`Server running on http://localhost:${PORT}`));

AutoHotkey Script

AutoHotKey
This is the script that is ran by AutoHotkey once triggered to open up a google classroom tab
Run("chrome.exe")
Sleep(100)
Send("https://classroom.google.com/u/2/" "{enter}")
