If you've ever tried to use SPIFFS on the Dev version of the SparkFun ESP8266 Thing, you will quite likely have encountered the error message "SPIFFS Not Defined for SparkFun ESP8266 Thing Dev" as soon as you tried to upload a disk image using the ESP8266 Sketch Data Upload tool from the Arduino environment. This blog has some background info on this, but for those who are impatient, I'll give you the solution first. The Problem The SparkFun ESP8266 Thing Dev board definition is missing some e ...
Firmata is a protocol that is used to communicate with microcontrollers from any tablet/pc over the serial interface. There are implementations of Firmata for many other platforms too along with Arduino. You can find support for Firmata if you are using any Arduino IDE released after 2008.Use of Firmata lets you access GPIO of Arduino from any host device natively without uploading the sketch each time you change the sketch. You can use Arduino as ADC for your Pi as it doesn't have native ADC pi ...
  Grbl is a free, open source, high performance software for controlling the motion of machines that move, that make things, or that make things move, and will run on a straight Arduino. If the maker movement was an industry, Grbl would be the industry standard.   Most open source 3D printers have Grbl in their hearts. It has been adapted for use in hundreds of projects including laser cutters, automatic hand writers, hole drillers, graffiti painters and oddball drawing machines. Due ...
This is Bernie, she lives with me in a vivarium, monitored by an Arduino.   You see, Bernie is a Crested Gecko (Crestie), and unlike most lizards that are kept commonly as pets, Crested Geckos need a mixed environment to ensure that they can comfortably survive in their habitat. Most lizards, such as bearded dragons, require sand, a heat lamp, ultraviolet light, and perhaps a small, covered space to hide in to help regulate their temperature.   We do not know a great deal about Crest ...
Hello community. I was developed my own application for Arduino developers and today i had published it on Google Play. This app bring you flexible and configurable remote for your arduino devices via bluetooth modules HC-05, HC-06. This is free application and i hope i can use this place for show it. Also i hope i can get some feedback and if i will see my app is in demand, then i will improve it. I have some ideas how can do it. Also i will be happy to see any suggesting for future updates. &# ...
Arduino Home An Open-Source platform to create digital devices and interactive objects that sense and control physical devices. Arduino Tutorials Arduino Projects   I was able to get a way from my booth at the 2017 Bay Area Maker Faire long enough to catch Massimo Banzi's annual State of Arduino speech. It was during one of these speeches late last year that Massimo announced that Arduino would be reforming as a single entity, removing a measure of uncertainty that was clouding the futur ...
I'm writing this as a "Blog Post", because I did not see a way to make it a document: Which I would have preferred.   I ran into a problem on the Intel Edison board, that stuck me for a while on coding, until I finally found the issue was with the Arduino Atmega328 chip on the Intel's Arduino breakout board. My personal problem was that I was unable to run I2C while using some of the Analog pins. While the detailed hardware information can be found linked below, I wanted to create an "easi ...
This is my first use of transistors in a project. I need to control a SainSmart 16-Channel Relay Module using an Arduino 101(3v3 GPIOs). This Relay Module uses 5 vdc through Opto couplers to power the relays. The input pins on the relay board are at 4.4 vdc and need to be brought to GND to switch on. When I connected the Arduino 101(3v3 GPIOs) directly to the relay module some of the relays would stay on while others would be controlled by the Arduino. It all worked fine when I tried an Arduino ...
This video is all about interfacing BMP180 module with Arduino. BMP180 will help us to measure environmental temperature  and pressure and by using that we can calculate the altitude which can be used in various applications like weather monitoring, navigation etc. The BMP180 sensor module comes with I2C interface and with a default address 0x77 which is not configurable limiting stacking of multiple modules to that same I2C bus. In this tutorial we will interface the module with Arduino by ...
What do you thing about this project? Have you some interesting ideas for expansion?   ...
Arduino users and other embedded system designers can now make user interface on the smartphones without wireless or app coding!!        https://www.kickstarter.com/projects/481671730/app-enable-products-without-writing-wireless-or-ap  ...
  The ESP8266 is a low-cost Wi-Fi chip with full TCP/IP stack and microcontroller capability produced by Shanghai-based Chinese manufacturer, Espressif Systems.The chip first came to the attention of western makers in August 2014 with the ESP-01 module, made by a third-party manufacturer, AI-Thinker. This small module allows microcontrollers to connect to a Wi-Fi network and make simple TCP/IP connections using Hayes-style commands. However, at the time there was almost no English-language ...
This blog documents some belated progress on my Star Trek themed Pi IoT design challenge entry. It is being put in the arduino area since that is where it is most useful. I wanted to make the subsystems useful and built well enough to work reliably in their target environment, so this sensor array is built using a custom PCB. The PCB did not arrive until well after the challenge was over, but it worked perfectly with no errors when I assembled it. The card features an arduino pro micro which ...
I've been looking into designing my own Arduino programming and development board after seeing Ben Heck's episode. Apologies if this is in the wrong area.   So I made a quick Schematic in Eagle using the arduino schematic from the website, I've included support for the ATTiny85. I know this isn't the first time someone has done something like this, or with home pcb manufacture, just wanted to share some of the problems I've had with this design.   So here is the final result, I don't ...

Ublox Neo-6m from E-Bay

Posted by ajens23 Nov 9, 2016
Ublox Neo-6M  from E-bay Hi All,   (First time trying this so please forgive if it's in the wrong place/format/whatever)   Just received a couple of Ublox Neo-6M GPS boards from E-bay and thought I would try a quick review for anyone interested. Board: GY-GPS6MV2 with Ublox Neo-6M Seller: Worldchips Shipping: included Price: 17USD(+/-) Apparently this board contains a voltage regulator (5 pin chip to left of RX/TX pins) and can be powered off of a 5V supply. I am usin ...
