The LED Strip Jellyfish Costume with Arduino & LPD8806 Led Strips

It all started when I saw a BBC documentary in 2002 about deep waters of the ocean. There was a biolimunescent jellyfish in the documentary, probably of the species "ctenophores" that grabbed my attention so in the later years I decided use it as a Halloween costume. It wasn't until 2011 when the led strips using LPD8806 driver chips came on to market that I found the opportunity to do this cost effectively ...

How to use a while loop to calibrate the value of an analog sensor using Arduino

Sometimes you want everything in the program to stop while a given condition is true. You can do this using a while loop. This example shows how to use a while loop to calibrate the value of an analog sensor. In the main loop, the sketch below reads the value of a photoresistor on analog pin 0 and uses it to fade an LED on pin 9. But while a button attached to digital pin 2 is pressed, the pr ...

Arduino-l3dgecomm – Integrating L3DGEWorld and Arduino

L3DGEWorld is a tool for monitoring and interacting with networks and computer systems. Within a 3D world, entities bounce, spin, scale and otherwise change. These entities all represent an entity in another context - be it a server, phone, router or other monitorable device. The visual transformations represent various characteristics of these entities, such as packets per second, CPU load, memory usage or ...

Mailbox Phone Alert

The mailbox phone alert sends you a text whenever you get mail. I remember anxiously checking my mail multiple times a day during the spring of my senior year of high school as I awaited letters back from colleges. Nervously, I would walk up to the mailbox. My heart would skip a beat as I opened it. Nothing inside. I would then go through the same process an hour later. I thought, if only there were a solut ...

MotherBone PiOne on Kickstarter

MotherBone™PiOne™ is a peripheral motherboard for BeagleBone Black & Raspberry Pi providing safe I/O expansion for Linux based systems The Background We were evaluating BeagleBone Black and Raspberry Pi for low cost control systems when we discovered that the modules, as shipped, were fundamentally unusable for anything other than connecting to your PC and programming. For instance, some of the cautions ...

Tree Climbing Robot using Arduino

After I got comfortable programming and building with an Arduino, I used my newly acquire microcontroller skills to build a robot.  Using a microcontroller, four high-torque DC gear motors, spiked legs, a linear actuator, rotation sensors, and 3 L298 H-bridge circuits, this robot can climb up trees of varying diameter.  The very long build log follows. I started out by creating a basic design in Sketchup. T ...

Palm Arduino Board V3

I design and create this Palm Arduino V3 prototype PCB, as I was tired of recreating Arduino Compatible on perf board every time I prototyping a new project, especially when I had to spend  a lot of time tracing the wiring to see that I made the right connection. I design this Palm Arduino (version 3) prototype PCB to be encased by Lego bricks, especially Lego Technic Bricks, for the reason that I was hooke ...

How to make a XY-plotter with Makeblock

Last month, I made a XY-plotter by Makeblock and use it to built a Drawing Robot. This Drawing Robot was built with two Linear Motion Shaft D8x480mm, two Long Beam0824, the timing belt, two stepper motors, two stepper motor driver, and a micro-controller Arduino.  You can send a picture from the phone or you can take a picture by the phone and then send it to the robot by Bluetooth. After that the robot wil ...

chipKIT Tutorial 6: Inter-Integrated Circuit (I2C) communication

I2C or IIC (Inter-Integrated Circuit) is a simple bidirectional serial interface, which requires only 2 signal lines for data transfer. It was originally developed by Philips in 1980′s to provide easy on-board communications between a CPU and various peripheral chips in a TV set. Today, it is widely used in varieties of embedded systems to connect many low speed peripherals, such as external EEPROMs, sensor ...

Best RGB LEDs for any project (WS2812)

When we're working with LEDs, we often like to control their state (on/off), brightness, and color.   There are many, many different ways of going about this, but none are as compact a solution as the WS2812 RGB LED.  In its tiny 5mm x 5mm package, the WS2812 includes 3 super bright LEDs (Red, Green, and Blue) and a compact driver circuit (WS2811) that only requires one data input to control the state, brig ...
