Have you ever heard of TFT LCD screens? They are great ways to display information from your Arduino, or display pictures. The Arduino team just released an official TFT LCD screen with their new Robot at Maker Faire 2013. It’s very easy to get started with!! This tutorial will show you how to get the LCD up and running, load information from the SD card, and make a few simple projects.
The TFT LCD screen is a great way to detach your computer, and have the Arduino relay information that you need to know onto the LCD. A great part of the LCD is that it has a built in microSD card socket. You can store images on the microSD card socket, and even some text!

If you’re like me, after I got my Arduino and performed a final programming on my first chip, I wanted to pull it off my Arduino Duemilanove and put it on my own circuit. This would also free up my Arduino for future projects.
The problem was that I’m such an electronics newbie that I didn’t know where to start. After reading through many web pages and forums, I was able to put together this Instructable. I wanted to have the information I learned all in one place, and easy to follow.

After making a 8X10 matrix a lot of people asked me about expanding the matrix to some thing bigger, and some wanted to write stuff to the matrix via a PC, so one day I looked at a pile of LEDs that I had leftover from a LED cube projected and I decided to make a bigger matrix with all the things people wanted.

Yep – One of those! This Instructable extends my Arduino Ethernet controller to control a set of up to 6 relays, but that’s not the neat bit. The neat bit is that there is a web based state machine in the AtMega chip so that the relays will operate in whatever sequence with whatever timing you want – all by themselves. This allows you to have a set of relays connected to the end of a piece of Ethernet cable that can be accessed from a web browser anywhere from your house.

This project is named “Engadino” after Engadin – ski resort in Switzerland. The reason for this is that I live in Switzerland, I like skiing and the name is easy to remember and pronounce. By itself the project is a clone of “Pinguino”.

There are many electronic devices that use the SPI bus, or Serial Peripheral Interface bus, for communications (e.g. various sensors, LCD displays, digital potentiometers, D/A and A/D converters, wireless transmitters and receivers, audio volume controls). The devices receive data serially from a microcontroller using a 3-wire set-up that includes a chip select signal (usually titled CS – when this signal is at logic 0, a chip recognizes it will be receiving or sending data), a clock signal for clocking the serial data into the device, and the serial data stream itself.

For relatively small (less number of pins than ATmega328) projects, ATtiny series, ATtiny45 or Attiny85 are good choice in terms of its physical size (8-DIP or 8-SOIC) and low power consumption. There are many ways to program it. One of the popular device is USBtinyISP and DASA. Both of them work very well with WinAVR (AVRdude).

The temperature in my office at work varies quite a bit depending on the time of day, season, and the whims of the other people I share the floor with. When I’m sitting at my desk shaking uncontrollably or sweating profusely it would be nice to know if it’s due to the temperature or just work related stress. A simple $5.00 thermometer would suffice, but where’s the fun in that? Making my own thermometer might cost ten times as much, but I might learn something in the process and it would be way cooler than any cheap store bought thing? I’d rather make something myself even if I have to pay a “maker’s premium.”

Combining Arduino and other shield modules, we make a mobile phone named Arduino Phone. Meanwhile, we printed a shell for it with the 3D printer. Although it’s not such fine as you think, even a little bit clunky, it’s still very cool. That is the point this is a cell phone made by ourselves. While, we can’t install Arduino Phone Apps limited by Arduino. So, if you want to play Angry Birds, then you need to do some big modifications on Arduino Phone.

Waveform generators (also called function generators) are useful for testing and debugging circuits. They can be used to test the frequency response of electronic components like op amps and sensors or to characterize and troubleshoot audio effects boxes and pedals. This waveform generator shield is powered by an Arduino. It outputs four waveforms: sine, triangle, pulse, and saw, each waveform ranges in frequency from 1Hz-50 kHz. The frequency, pulse width, and overall amplitude (gain) of the waveforms is controlled by three potentiometers.
