Basic Information

This page allows you to edit the existing project (Visitor Counter). The edited project will replace the existing entry in the IoT Projects page. If you want to add a new entry based on the project, please fork from it instead.

* Photo URLs that end with any one of .jpg, .jpeg, .png or that are uploaded to the Gyazo web service in the PNG format (e.g.https://gyazo.com/hogehoge) are supported.

* Node.js entry point main: index.js and dependencies to the npm module dependencies: { f3js: (略) } will be automatically added and thus do not need to be in this form.

Private Project

This project is already public and cannot be made private.

Source Code

Provide the source code of a microcontroller or tiny computer in JavaScript. Node.js-based computers are supported. Require f3js package and use its API to design the device enclosure.

var f3js = require('f3js'); var x = 5 /* Offset x [0, 100] */ , y = 5 /* Offset y [0, 100] */; f3js.drawRectangle(x, y, 195, 70); // load drivers. var grove = require('jsupm_grove'); var groveMotion = require('jsupm_biss0001'); var GCL = require("jsupm_my9221"); var tm1637 = require('jsupm_tm1637'); var LCD = require('jsupm_i2clcd'); // instantiate a circular led driver. var circle = new GCL.GroveCircularLED(3, 2); // Initialize 4-digit display and Jhd1313m1 LCD display var display = new tm1637.TM1637(4, 5); var myLcd = new LCD.Jhd1313m1(0, 0x3E, 0x62); myLcd.setColor(255, 0, 0); // put the circular led and displays. f3js.add(circle, x + 30, y + 30); f3js.add(display, x + 80, y + 20); f3js.add(myLcd, x + 150, y + 27.5); //f3js.drawRectangle(x + 105, y + 37.5, 5, 10); var level = 0, colon = true; function rotateSpinner() { var date = new Date(); var time = ("0" + (date.getHours()+9).toString()).slice(-2) + ("0" + date.getMinutes().toString()).slice(-2); display.writeString(time); display.setColon(colon); circle.setSpinner(level ++); if (level > 24) level = 0; } var circleInterval = setInterval(rotateSpinner, 100); // instantiate a motion sensor. var sensor = new groveMotion.BISS0001(8); // put the motion sensor. f3js.add(sensor, x + 80, y + 50); f3js.drawRectangle(x + 55, y + 44, 5, 10); var counter = 0, lastTime = 0; function readSensorValue() { var date = new Date(); // detect motion. if (sensor.value() > 0) { console.log('o ' + date.toString()); var time = date.getTime(); if (time - lastTime > 5000) { countUp(); } lastTime = date.getTime(); } colon = !colon; } function countUp() { counter ++; var counterString = '' + counter; if (counter % 10 === 1) counterString += 'st'; else if (counter % 10 === 2) counterString += 'nd'; else if (counter % 10 === 3) counterString += 'rd'; else counterString += 'th'; myLcd.setColor(255, 0, 0); myLcd.setCursor(0,0); myLcd.write(counterString + ' visitor'); myLcd.setCursor(1,0); myLcd.write('running on f3.js'); } var sensorInterval = setInterval(readSensorValue, 1000); process.on('SIGINT', function() { clearInterval(circleInterval); clearInterval(sensorInterval); });
