Arduino uno r3 circuit diagram. 50 we sure love the atmega328 here at adafruit and we use them a lot for our own projects. I was looking for some type of touch screen for the arduino when i ran across this little gem on ebay. The arduino uno is an open source microcontroller board based on the microchip atmega328p microcontroller and developed by arduinocc.
Current models consists a usb interface 6 analog input pins and 14 digital io pins that allows the user to attach various. Image developed using fritzingfor more circuit examples see the fritzing project page. Arduino can interact with buttons leds motors speakers gps units cameras the internet and even your smart phone or your tv.
Arduino is a single board microcontroller meant to make the application more accessible which are interactive objects and its surroundings. Arduino is an open source platform used for building electronics projects. Arduino consists of both a physical programmable circuit board often referred to as a microcontroller and a piece of software or ide integrated development environment that runs on your computer used to write and upload computer code to the physical board.
The hardware features with an open source hardware board designed around an 8 bit atmel avr microcontroller or a 32 bit atmel arm. Connect three wires to the board. The processor has plenty of gpio analog inputs hardware uart spi and i2c timers and pwm galore just enough for most simple projects.
Please visit this page before you go where i also have a sketch that attempts to read the lcds driver code without any additional libraries. The first two red and black connect to the two long vertical rows on the side of the breadboard to provide access to the 5 volt supply and ground. Id like to start compiling information about the screens people are using.
The board is equipped with sets of digital and analog inputoutput io pins that may be interfaced to various expansion boards shields and other circuits. The board has 14 digital pins 6 analog pins and programmable with the arduino ide integrated. Adafruit industries unique fun diy electronics and kits adafruit metro 328 fully assembled arduino ide compatible atmega328 id.
The arduino platform has become quite. The following two examples both use three buttons connected to the arduino. Open source electronic prototyping platform enabling users to create interactive electronic objects.
