After setting up Eclipse M2M toolchain for Raspberry Pi, I wanted to try out a simple lua script to blink LEDs using GPIOs. Here is the schematic and lua script for the same. I used the 3.3V available on RPi for powering the LEDs. 1 kiloohm resistors were used to limit the current passing through […]

After some days of soldering, testing and coding I am now able to control my LED marquee remotely via bluetooth from my Raspberry Pi. Using an Arduino Pro Mini (5V model) and the HC-05 module mentioned in my last blog post, I was able to mount all components inside the sign’s housing. Some features of

Almost all wireless technologies use some kind of association process to enable devices to join the network. Such a process is typically initiated by pressing a button on the network controller and by subsequently pressing another button on the device to associate. Software gateways, like Dog, cannot naturally support this press-and-join interaction and the association

If you do a web search for LED cubes, you will notice that they have been built so many times and anything less than 8x8x8 is a bit of a waste of time. Knowing all of this, and basically because I am bored out of my mind, I decided to go ahead and build one
