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) ...

Transcompile Arduio TFT GUI Sketch from SVG File

Posted by:

Preamble

Let machine do the dirty work. To continue what I started in last post, I tried to see if it is possible to parse the SVG file and generate arduino sketch code out of it. The answer is yes. There is a wonderful post and a SVG Optimiser which helps me greatly for this project.

Parse the SVG file with the powerful lxml to generate an element ...

Access SD Cards from TFT LCD Shield Using Arduino Mega 2560 Soft SPI

Posted by:

Preamble:

Some things to keep in mind when using the SD Library -from official site and SD library

The communication between the microcontroller and the SD card uses SPI, which takes place on digital pins 11, 12, and 13 (on most Arduino boards) or 50, 51, and 52 (Arduino Mega). Additionally, another pin must be used to select the SD card. This can be the hardware SS pin – ...

Arduino TFT LCD GUI – Load Bitmap Image

Posted by:

Preamble

There are two ways to draw bitmap images in Arduino TFT LCD – to draw from SD card, or convert them into byte array. The first is more powerful and works with true color bitmap images; the 2nd approach is more suitable for simple logo and monochrome images, and there is no need for SD capability for this method.

Convert Images to C++ Byte Array

There are a ...

How to Make a GUI for Arduino TFT LCD

Posted by:

Preamble

There is no package available which offeres a visual graphic display as well as the coordinate info so that you can reproduce it with TFT graphic library. 4D Systems is the closest you can get, yet it is lousy, proprietary and only available for Windows. After researching long and hard for a GUI Designer for Arduino TFT LCD, finally I think I come up with a reasonable implementation – SVG vector ...

Compile and Upload Arduino Sketch with PlatformIO in Arch Linux running on PC, Raspberry Pi 2 and 3

Posted by:

Preamble

PlatformIO is a python tool to build and upload sketches for multiple Hardware Platforms, at the moment of writing these are Arduino/AVR based boards. This is the only tool working with Raspberry Pi running Arch Linux so far, and I have been searching for some tool like this for a long time.

NB: The over-bearing minion is there because every time my little one sees it, she giggles.

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
