In this post, we continue exploring the DIY NodeMCU Anemometer project by diving into Part 2 – the software. This article follows the first tutorial, How to Build Your Own Anemometer Using Reed Switches, Hall Effect Sensor and Some Scraps on Nodemcu – Part 1 – Hardware, where the wind speed and direction measurement devices […]
When it comes to debugging a microcontroller circuit, there aren’t a lot of simple options. Since a microcontroller circuit might have multiple things going on at the same time, measuring voltages with a DMM isn’t an option. Using an computerized In-Circuit-Debugger solution is expensive and elaborate, and time-consuming to set up. People often resort to
The assignment for this week is to automate the machine assembled two weeks ago. For this Roxanna milled the Arduino’s shield for controlling the steppers, but Alejandro found that we haven’t all the components for stuffing, specially the A3982 – stepper motor driver, so as was impossible to get it locally, I decided to design
These days I was reading an interesting post on how to make yogurt “by the gallon,” which explained the need to maintain a constant temperature of about 43ºC (110°F) so the bacteria can grow properly. Commercial yogurt makers are available, but they’re usually too small for producing a full gallon at once. Building your own
This project details a Flowcode and E-blocks based weather station capable of reading local temperature and humidity with 2 remote thermo-hygrometer sensors. The local board also incorporates a real time clock. This article has been contributed by Flowcode user John Crow. Flowcode can be downloaded and trialled for free at the Matrix Technology Solutions website.

In this guide I will explain how to use a Windows 8.1 phone, Arduino Uno board, and HC-05 Bluetooth module to build a wireless oscilloscope. The phone application has the critical functions of an oscilloscope, although the bandwidth is a measly 300 Hz. Still, if you want to see squiggly lines on your phone, it
This project shows how to send SMS text messages to a cheap scrolling LED display via an Android app and arduino with USB host shield. The project was originally inspired by a friend wanting to make a “sexting themed” costume, with a scrolling LED display of live texts sent from people at the party. We

Havahart traps are really nice if you have pests to rid your home of but you don’t feel the need to do this through means of killing the animal. The problem we are faced with is constant monitoring of the trap. If you forget to check back frequently (usually at least once a day), you
This Instructable will tell you how to use the IR (infrared) library on an Attiny. I will be using an Attiny85 with an Arduino Uno. I won’t cover how to upload sketches to the Attiny just how to use the IR library with it. the best tutorial on uploading sketches I’ve found is this YouTube

Simple Animatronics with Servos and Arduino using arduino Servos are surprisingly easy to use. Even more so than simple DC motors and steppers when you have a microcontroller. In this instructable we’ll use a ‘duino to drive five servos which will control a doll’s limbs and neck. I bought the servos at HobbyPartz for a
