Once you have compiled your C or C+ program into an AVR binary using AVR-GCC, you will need to `burn` it to the chip itself. This can be done with one of three applications: AVRDUDE, UISP, or AVR Studio. In order to actually get one of those applications talking to your chip, you will need hardware to plug the chip into your computer.

There are five pins on the chip for something called an In-System Programmer, or ISP for short. These pins are used by your computer to program the chip. A common piece of hardware for connecting these ISP pins to one of your PC`s USB ports is the AVRISP mkII. These usually sell for $25 to $30, and are one of the easiest programmers to use. If you don`t feel like going for one of those, you can also build your own Parallel Port ISP programmer without trouble. There are a number of designs for a parallel programmer, but this is the simplest. Arduino is an AVR-based prototyping board with an emphasis on ease of use. It has breakout headers for I/O pins and power. It also features a USB interface using the FT232RL chip, which allows RS232 serial communication through a USB device, eliminating the need for a separate AVR programmer. The Arduino project also has an Integrated Development Environment for writing AVR code in a C/C+-derived language called Wiring. The IDE also includes many helpful libraries and a nice function framework. Check out the Arduino website ! The Arduino bootloader will flash Pin 19 (PB5) twice on a 500ms interval at boot-up. The low-power LED is meant for this, or for your own software`s status monitor. Use the 470 ohm resistor in series with the LED. ATmega chips programmed by the Arduino will work as stand-alone microcontrollers. However, in order to use a new ATmega with the Arduino, you must write...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
