Internet of Things and Hardware Hacking (Part 1) -A Web Controlled LED Digit Display

Posted by:

Preamable

This was the very first project RLM, Limdo and I did about a few month ago – a very simple project which covers the whole nine yards of internet of things, from basic concept to final implementation. I have been so intrigued by the wonder of electronics and programming world ever since.

The task of this project is to: 1) use Arduino to control 13 LEDs for a digit display, 2) ...

The Computational Virtual World and the Real Physical One

Posted by:

Preamble

It is always fascinating when the virtual reality starts to compete with real world, particularly when one can track user’s locomotion, head movement, gestures, EEG and vital statistics etc. Here is just a little teaser project about virtual reality.

Parts needed

  1. Breadboard
  2. Arduino Uno or other board
  3. Hc-sr04 Ultrasonic Distance Measuring Sensor
  4. connecting wires

Arduino Interrupts and some of its Usage

Background and rational

In the process of developing a device, we come across a situation that we needed a responsive way to abort the device; However Arduino will be stuck in the middle of loop and only response after that, esp when the only communication to Arduino is via a serial port. We have adapted a very wasteful way of putting the whole ...

Arduino Installation on Raspberry PI 2B Running Arch Linux

Posted by:

Official Arduino IDE does not agree with PI and it sucks any way.

[update] Platformio is a better way!

There are two major ways to compile and upload sketch files to Arduino: a. use IDEs (Arduino IDE, Emacs IDE, Fritzing or ArduIDE). or b. use a terminal. Arch official site explains well, however, most of it does not apply to RasPi with Arch Linux. It DOES work with regular ...
