Internet-Controlled RC Car using Arduino

The Internet Controlled RC Car allows you to remotely drive around a small rc car from wherever you may be and see where it is going. This is fun because you can remote explore whatever space you leave it in, or hand over the keys - so to speak - and allow someone to drive around your space. This is also a great building block for a telepresence robot. This project is also a great beginner project for someo ...

Arduino Seismic Activity Monitor – Ethernet Shield

Have you ever wanted to impress your friends by saying something crazy like, "I think there's going to be an earthquake soon" moments before an earthquake hits? Or do you just want some warning, a few seconds that could save your life. This project will allow you to hook up a seismic sensor to a router through the Ethernet shield and host a webpage off of the SD card on the shield. This webpage will then di ...

Web Client using Arduino

This example shows you how to make a HTTP request using an Ethernet shield. It returns a Google search for the term "Arduino". The results of this search are viewable as HTML through your Arduino's serial window. Circuit The Ethernet shield allows you to connect a WizNet Ethernet controller to the Arduino via the SPI bus. It uses pins 10, 11, 12, and 13 for the SPI connection to the WizNet. Later models of ...

Twitter Physical Client

In this project I’m building a physical Twitter client using Arduino and a flag, basically an arduino powered retweet indicator, whenever any of my tweets is retweeted some physical action will happen to notify me of that. You'll need: 1. Flag. 2. Arduino. 3. Laptop with a java IDE installed on it. 4. Yellow Led 5. 330 Ohm resistor 6. Servo motor (even a weak one would do, you don’t need a lot of torque) 7. ...

Smart Homer Web-enabled TV remote using Arduino

Smart Homer, a Web-enabled TV remote puppet Smart Homer is a Web-enabled puppet that turns on your TV when Simpsons is on. As Homer is too lazy to browse the Web himself, a script in the cloud checks the online TV program for him. If Simpsons is on, the script triggers the Arduino Web service in Homer's belly to activate his infrared eyes. No brain involved. This project by @tamberg was built at the 24-hour ...

How to build an Arduino WiFi 4×4 with Android Controller

RC cars can be WiFi Cars...? RC cars are cool, but cheap RC cars have limited range and can only be controlled with the particular controller that was included with the car. I purchased a RC jeep, complete with 4 wheel drive, flexible suspension, and off-road tires for about 30 bucks. Not long after playing with the car I determined that I could improve it by using WiFi and Android. So I wasted little time, ...
