The regular Hackaday reader no longer needs to be reminded about how popular the ESP8266 is; they see the evidence of that several times a day. But what might not be quite so obvious is that it isn’t just us hacker types that are in love with the inexpensive IoT microcontroller, it’s also popping up more and more frequently in commercial products. As [Majenko] demonstrates, one of those ESP-powered devices ...

Introduction In this tutorial, we will go over how to connect an OpenScope MZ to LabVIEW. To do so, I will be walking you through some example VIs that I made. These examples allow you to access the oscilloscope and Wavegen/DC power supply functions of the OpenScope as well as the GPIO pins and the Logical Analyzer. Materials Hardware OpenScope MZ Software LabVIEW NOTE: Installing LabVIEW requires you creat ...

Internet of Things (IoT) is one of the most important technologies these days. It became an essential component of many hardware projects core. And in order to make it easier for developers, Bolt IoT platform appeared as a complete solution for IoT projects. Bolt is a combination of hardware and cloud service that allow users control their devices and collect data in safe and secure methods. It also can giv ...

Over the Christmas break, my parents were out of town to celebrate the holidays. When they came back, they saw something every homeowner fears – a flooded basement. In a basement, there are pipes that collect water from around the foundation and bring it into the sump pit, which pumps it out away from the house. When the sump pump fails, water has no way to leave the basement and it floods. I recently bough ...

by Derek Hildreth – Technologic Systems This comprehensive and easy to read example C code is designed to work alone or included as a library for dealing with general purpose I/O via the sysfs interface in Linux.  It can easily be applied to any computer which utilizes the GPIO sysfs interface (both pro and maker boards).  Getting started is a breeze.  You just need to decide if you’re going to use it as a ...

A PC application that talks to the Walabot PRO, Arduino and NeoPixels! Story Welcome to my Walabot project I will split this project in different parts 1. Get to know the Walabot and a setup. This includes data readout and send it to an Arduino. 2. Gather the data that is needed for the calculations and create an image with this data 3. Convert the data to an object Getting started with the Walabot I've mad ...

ESP8266 is a great thing for starting to Wifi And IOT It is also cheap and be used for making cool projects connected to the Internet .Learn how to make a simple IOT Project with it .The ESP8266 WiFi Module is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-F ...

The ESP8266 has a few common issues, specially when you are trying to flash a new firmware or uploading scripts. This is a companion guide to the Home Automation using ESP8266 and Password Protected Web Server eBooks. Here’s a compilation with some of the most common problems with the ESP8266 and how to fix them. ESP8266 Troubleshooting – NodeMCU Flasher Where do I download the NodeMCU flasher? Go to the No ...

This a door lock built as fun project.It is quite easy to build and a fun way to learn and improve your knowledge of arduino.I tried to add a 16*2 display but there werent enough GPIO pins on arduino Uno.If You are interested in adding a display you would need an arduino Mega. Items Needed Arduino UNO Jumper wires Servo(or anyother component to open a door lock like a linear actuauator) Keypad(I used a 4*3 ...

Story Wiscore: Integrating Arduino with Alexa As part of the series of tutorials for the Wiscore Alexa AVS EVK, we will see how to integrate Arduino boards (Uno, Leonardo, Due etc) directly with Alexa Voice Service. The Wiscore board provides the means to communicate with other devices via the UARTs. We will in depth on how to enable one of the UARTs, connect an Arduino to the EVK and then communicate over ...

It’s been a while since I posted a new article, a delay at least partly due to me herniating a disc in my neck which left me completely unable to look downwards for any length of time and as you’ll know all too well you can’t work on circuit boards without peering down at them. Look after your neck and back folks, and I mean that seriously. Well I’m back now and I’ve got a lot of ideas for articles spinning ...

The ESP8266 is a great tool for enabling your project to access the internet. You can plug it into an Arduino easily as shown and allow your project to communicate through the internet. Or even more exciting, to control it from anywhere in the world! The ESP8266 is a very low-cost module that comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your Arduino device an ...
