Arduino LED Wall clock using WS2811

FUJZPOZIGJOT0EO.MEDIUM

This is a big LED digit wall clock based on Arduino and WS2811. Features :

  • big digits ( each digit is approximately the size of a A4 paper).
  • slim in order to fit in a photo frame (a big one).
  • auto dim the light depending on the light in the room.
  • dedicated DST button.

by Alexis Ospitia @ instructables.com:

In today’s technology, especially electronics have come a long way, to the point that today can make projects a few years ago were very complicated to implement, thanks to these technological advances are now able to design and implement our houses projects.

and through this article I come to show you my new project, which consists of a wristwatch, so I called Arduino Watch Sport.

Arduino Project: MP3 player using Arduino and DFPlayer mini MP3 player module

Building an MP3 player with Arduino is extremely easy. We use the DFPlayer mini in order to build a simple MP3 player. The MP3 player has 3 buttons, in order to Play/Pause, to load the next song and one in order to load the previous song. In this video we are using an Arduino Uno, but you can use any Arduino board you like.

Lie Detector and Biofeedback Arduino Based

by masteruan @ instructables.com:

This tutorial will explain how to build a machine for biofeedback. But first a bit of theory.

What is biofeedback?

Biofeedback is the process of gaining greater awareness of many physiological functions primarily using instruments that provide information on the activity of those same systems, with a goal of being able to manipulate them at will. Some of the processes that can be controlled include brainwaves, muscle tone, skin conductance, heart rate and painperception.
Biofeedback may be used to improve health, performance, and the physiological changes that often occur in conjunction with changes to thoughts, emotions, and behavior.

A Tutorial For Launching Your First Balloon

2015-10-05-13.38.32-2

Here is a nice tutorial about launching you first ballon into space. Also tracking device information is provided. Source is available here:

There are a lot of reasons to put together a weather balloon launch. Its a great project for a STEM /STEAM class, it requires planning, electronics and programming, and teamwork. It has a lot of great classroom applications, giving a tangible demo of aerodynamics, physics, meteorology, geology, and more. Additionally its a great way to get amateur radio into the classroom and get a new generation into this great hobby. Outside of classrooms there is citizen science to be had, gathering your own data of atmospheric conditions or testing devices in space like conditions. And finally there are the amazing photos and videos that can be made only with weather balloons. Above all launching weather balloons is a lot of fun and a great challenge.

This is a simple tutorial to create an EMF detector. You can use Arduino for this job, but is better use a microcontroller called Attiny85. It is possible program it throe the Arduino interface.

Arduino with GSM and PIR Sensor

by motheeb @ instructables.com:

This lesson will allow you to use SMS to control an LED along with using Arduino to make automatic calls to your phone in case it sensed movements in your room. You will be able to listen to the voices there and act upon emergency.

DIY Capacitance Meter

diy-capacitance-meter-picofarad-620x471

electro-labs.com published another great project based on Atmega328P:

We are building another opensource SoloPCB project which is very enjoyable to build and use. In our electronics works, we frequently need to know the actual value of a capacitor. As you know, small sized SMD capacitors have no markings showing their values. Or there are lots of fake electrolytic capacitors which are rated much lower than their stated values. Sometimes the capacitors have large tolerances and we want to choose the best fit for our circuit. What we need is an accurate capacitance meter.

This is a capacitance meter which can measure capacitors rated from picofarads to millifarads. The principle of operation is simple. Just apply voltage to the capacitor and measure the elapsed time to charge it. The circuit is based on Atmega328P and it is Arduino IDE compatible. It includes the voltage regulators which output 5V and 3.3V from 9V input. A Nokia 5110 LCD is used to display the measured information. Thanks to the 4mm banana jacks, various kinds of probes can be used such as SMD probe, crocodile probe etc.

OpenduinoGSM an open source tool Arduino IDE compatible with Opengate project inside

Openduino_opengate

Emanuele @ dev.emcelettronica.com:

OpenduinoGSM is an open source tool for hobbyists & professional makers. The first project realized is the useful opengate (one ring with your phone and the gate is open). Inspired with OpenduinoGSM!

With OpenduinoGSM you have the option of using the Arduino development environment, so anyone, even those who are unfamiliar electronics and circuits, can try to realize the automation they want by writing simple code in C ++ or by using one of the many open source projects published and modifying it according to their needs. The steps to make a control and/or a wireless automation are few and simple:
