Music Party is a Facebook-connected Music Party is an Arduino project that plays the liked artists of anyone who tags into the system with an RFID card, like a transportation card used in cities. The project uses Lifegraph Connect to manage the tokens between the physical RFID and the virtual Facebook ID. Lifegraph Labs uses the Lifegraph Arduino Library, which makes JSON APIs, like Facebook, easy and accessible from Arduino.

Many people dream of a hybrid between Arduino and Raspberry Pi. As did the folks from Texas Instruments, so they created the Beaglebone Black. It combines the best of the 2 worlds: From Raspberry Pi: built-in ethernet, fast Arm processor, HDMI, runs on linux and from Arduino: two 46-pin headers that are compatible with over 30 plug-in boards called capes. Consider these like Arduino shields.
This time the price is right too: $45.
I don’t know if this will pose a threat to Arduino, but I do know that competition is good.

Makezine reposted an extensive article from digital diner that compares the Arduino Uno vs BeagleBone vs Raspberry Pi. It’s a good comparision for beginners. It will show you the basic differences between the three boards, and help you decide which one is best for your project.

Photographer and Instructables user Alexander Morris created a giant Instagram inspired photo-booth and published all the steps to make one yourself. It’s the perfect solution to pimp-up your parties!
What’s inside of the box? An Arduino DUE coded to start the photo-booth sequence once the big red button is pressed and some other stuff.

This art project will put your Arduino in the cloud. Literally. It’s a cloud lookalike (you know, real clouds) that can change color,and can be controlled by an IR remote.
Several effects are possible:
- sun (white and yellow)
- rain (blue and white)
- lightning (blue and purple with flashing white)
- RGB flashing led
- and also on/off for each individual color

If you often run out of digital pins on your Arduino, this guide can be a solution. Anything as complicated as, say, a video game controller, was near impossible with the amount of pins available. Multiplexing buttons works, but it requires lots of connections and soldering.
In a circuit consisting of one resistor and a 9V battery, the resistor drops 9V across itself. So, the resistor’s forward voltage is 9V. Two resistors of equal value would each drop half the voltage, 4.5V, each being half the total resistance in the circuit. If one resistor is 100 ohms, and a second resistor is 300 ohms, each will have a proportional forward voltage. In a 12V circuit, the 100 ohm resistor would drop 3V and the 300 ohm resistor would drop 9V.
Basically, all of the buttons connect to the same analog pin. They also connect to positive via a 1K ohm resistor, and negative through different value resistors. When button 1 is pressed, the voltage level at Analog 0 is equal to {R2 / (R1+R2)} * Vcc or {100 / (1000+100)} * 5 = 5/11 of a volt or 0.45V. Solving for the other two buttons with 330 and 470 ohm resistors, we get 1.24V for button 2 and about 1.6V for button 3. We could continue adding buttons with higher value resistors, such as 680 ohms, 1.5K ohms, 3.3K ohms, and so on.

Some Arduino projects don’t need USB connectivity. In most cases it is only needed to program the Arduino and then it becomes a redundant part which takes place on board.
This project aims to make a USB to ttl interface on a very cheap tiny board. This thing is so small it doesn’t even need a USB cable, the USB connector is on the PCB.
On the picture you can see the difference in size with the official Arduino board.
Or, you could get something similar right here (affiliate link)

Hans wanted to connect his Arduino to the internet. You can buy shields for that, but they are quite expensive (like 40$). So he decided to look for alternatives and after a while he found 10$ ENC28J60 Ethernet modules on eBay. While they are not as full fetched as the official (Wiznet based) shield, they are certainly a lot cheaper.
As it turns out, it is quite easy to connect any (3.3 or 5V) Arduino to one of those modules with just six wires:
- ENC SO -> Arduino pin 12
- ENC SI -> Arduino pin 11
- ENC SCK -> Arduino pin 13
- ENC CS -> Arduino pin 8
- ENC VCC -> Arduino 3V3 pin
- ENC GND -> Arduino Gnd pin
Note: I found a similar module for $7.40 right here (affiliate link)

As seen in MotoGP Race, the rider is seen riding through corners while laying aside his bike to the left and right. But there is an interesting moment when the motor looks to collapse sideward, the front views remain horizontally. How could that be?
Such onboard camera applies GYRO system, where the camera will be fixed perpendicular to the gravity of the earth.
We could build our own Gyro Camera by using GYRO and ACCELEROMETER modules.
They are two separate modules, hence we have to use two modules simultaneously. Then we make Gyro Chip and Accelerometer Chip in one module (there are two chips in one module). In latest version they are made in one chip only, thus minimizing the distortion of movement calculation

Have you ever wanted to control electronics with your smartphone? The Arduino ADK (Android Development Kit) is the Arduino Mega with a built in USB host device, ready for your smartphone to be plugged in! This project is a simple introductory project with a few LED strips and a relay (to control the high voltages of the LED strip). For this project, you will need no Android programming experience (or even learn how to code Android!), but a moderate Arduino code understanding. We’ll use the easy Handbag app for Android.
This Instructable will cover how the Arduino ADK works, how to use it with Android devices, and how to make a cool example project of lighting up LED strips with Android!!!
