Do you need a quick and easy way to program AVR chips. Did you know you can use your Arduino and the Arduino IDE? This Arduino shield makes the process much easier.

A solar charge controller regulates the voltage and current coming from your solar panels which is placed between a solar panel and a battery .It is used to maintain the proper charging voltage on the batteries. As the input voltage from the solar panel rises, the charge controller regulates the charge to the batteries preventing any over charging.

One day I was sitting behind my desk at work and I got that weird need to build something, after looking around for a bit I got my eye on an LED matrix and that sparked an idea in my head : “I WANNA MAKE A TAMAGOTCHI”.
So for those of you that don’t know what the heck is a Tamagotchi here is a little snip-it from wikipedia :
“The Tamagotchi (たまごっち Tamagocchi?) is a handheld digital pet, created in Japan by Akihiro Yokoi of WiZ and Aki Maita of Bandai. It was first sold by Bandai in 1996 in Japan.”
So my take on this classic toy is to make it in to a desktop gadget with an LED matrix for a display, and an Arduino for brains to make it more accessible to people. With that said join me as we design,build and program the World’s first (As far as I know) desktop Tamagotchi.

This is a complete DIY project which requires a handful of components such as the ATtiny 85, LM35, MAX7219 and a couple of resistors and capacitors running off a regulated 5 V supply.
Temperature Measurement Range : 0 to 150’C / 32 to 300’F
Controller: ATtiny 85
Display type – 4 digit multiplexed 7 segment display (Common Cathode type)
Programming Language: Arduino
The setup can display both in Celsius and Fahrenheit. By default the temperature is shown in Celsius but can be toggled to display in Fahrenheit using the push button.

Here, we show how a 7 Bi-color 8×8 LED Matrix Scrolling Text Display is built, in which messages and commands can be sent to it via Bluetooth using an Android Smart Phone. Logically, any devices capable of sending text messages via Bluetooth may be adapted to work with the display.
To build this project, basic electronics component soldering skills and some knowledge on using the Arduino or Arduino based micro-controllers are required.
The reason for building a 7 LED Matrices long display is that it is quite adequate for ease of reading scrolling text and also because the largest tinted acrylic sheet easily available in Hobby or Art shops is 18 inches by 12 inches, which is just the right length for making the enclosure for the display as each LED matrix is around 60mm x 60mm in size.

This project turns the Arduino UNO into a computer running the BASIC programming. languagedan14 @ instructable.com writes:
Hi all, this is my first instructable documenting the creation of my project, the Arduino UNO BASIC shield which turns the Arduino UNO into a computer running the BASIC programming language.
As microcontrollers are essentially low performance computers on a chip (they have a processor, RAM and ROM) they can be used to create small computer systems. The aim of this project was to use AVR microcontrollers to create a computer capable of running the BASIC programming language.

So, what exactly is this about?
Imagine: You are working on a project. You want to program in the Arduino language because of the simplicy. But you don’t want to use a 28 pin monster. Or you need peripherals like CAN or similar what the normal Arduino supported MCUs don’t have. So, what to do? Where are two alternatives:
1. Just don’t use the Arduino language and use things like bits and ports what you can’t understand.
2. Or continue reading this!
So, this instructable is going to show how to use the core files available from avr-developers.com. I’m also going to show you how to program the different MCUs and how to connect them to do so. At the end I’m going to give some ideas on what you can to with your new knowledge earned from this.
