This tutorial is going to teach you the basics on using Flux Sensor of 2.2 inches. Step 1: Introduction Description: It is a flex sensor which is 2.2 inches in length. This sensor works by bending the sensor itself. As the sensor is being flexed or bent, the resistance across the sensor increases. The greater […]
This small Python script takes a KiCAD board (.kicad_pcb file) and produces a 2D nice looking drawing of the board as an SVG file. This allows you to quickly and automatically create awesome pinout diagrams for your project. These diagrams are much easier to read than a labeled photo of a physical board or an

I know the Z-Wave or Netatmo system for IoT, domotic system and automation of house. But now you can make an ESP8266 DoMo system. Story Introduction: Cayenne and SparkFun IoT 433 Mhz Sockets I know the Z-Wave or Netatmo system for IoT, domotic system and automation of house. But now you can make a simple
In this instructable I’m going to show you how to Interface with LED matrix using an Arduino and MAX7219 IC, this project can be used to make low resolution images using LEDs. This project is very simple to build and serves as a basics to getting started with controlling a large number of LEDs using
This instructable show how to test ESP board on bread board without soldering, especially for ESP-07 and ESP-12(E) and may be ESP-03. ESP board most require 2 mm pitch connector but most bread board are 2.54 mm pitch, It need some tricks on connect between ESP board and bread board. Step 1: Preparation 2 mm
The HMC5883is a digital compass designed for low-field magnetic sensing.This device has a wide magnetic field range of +/-8 Oe, and an output rate of 160 Hz. The HMC5883 sensor includes automatic degaussing strap drivers, offset cancellation, and a 12-bit ADC that enables 1° to 2° compass heading accuracy. All I²C Mini Modules are designed

Many devices are powered by USB power now, but few home automation systems provide USB power switching. “Alexa, turn off the ThingyStick!”. Story Alexa, Turn on the ThingyStick… Background More and more devices are powered by USB, many of these tend to be “dumb” devices without internet connectivity or home automation options (e.g. LED lights),
Time to get Pavlovian on your cat! Story If you ever tried to train a cat, you know how hard it is. Cats are their own masters, but now you have the chance to let the cats do your bidding using this IoT-enabled device. Welcome to Pavlov’s Cat Experiment! In this project, you will learn
Most of us who work with electronics know the name of Texas Instruments (TI) as a manufacturer of several important digital and analogue ICs as well as fancy sophisticated scientific calculators. However many people don’t know that TI is also a manufacturer of some of industry’s best microcontrollers. TI’s portfolio of micros is pretty large.
This project takes hourly temperature and humidity readings from a humidor. A Web API sends the readings to Azure SQL and Twitter. Story I WiFi enable something that that non-geeks would say “why did you do that?” I added a MRK1000 to a humidor. Every hour it sends temperature and humidity reading. Now according geek laws, if
