Its possible read GPIO value then GPIO direction is input. I try use GPIO package, but first value is 0 but should be 1. I use Raspberry Pi. var gpio = require("gpio"); var pin5 = gpio.export(18, { direction: "in", ready: function() { } }); function readInput() { a = pin5.value; if (a == 0){ pin3.se...

Yes something like this, but i try to send simple signal IR333C ant with TSOP38238 receive signal ant make event in nodejs, or like in your video with led. But all example with lirc and remote control. So maybe someone know how can i release that on raspberry. Anyone ?

Hello, its possible make IR sensor with TSOP38238 and IR333C using NodeJS ?

After 1-2 min. running web server on raspberry pi, i get lag. I use nodeJS, socket.io and sqlite database. I suspect this: io.sockets.on('connection', function(socket){ setInterval(function(){ fs.readFile('/sys/bus/w1/devices/'+ tempId +'/w1_slave', function(error, buffer){ // Read data from file (u...

But its not like simple gpio control and i cant understand how to check

But maybe there is a simple way through the command line?

How can i test relay circuit with DS2405 ?

Hi, maybe someone have simple example, that i can control 1 gpio pin via web using node.js and socket.io. I am not understand how should work button.
