Arduino uno r3 circuit diagram. Arduino is an open source platform used for building electronics projects. Current models consists a usb interface 6 analog input pins and 14 digital io pins that allows the user to attach various. The hardware features with an open source hardware board designed around an 8 bit atmel avr microcontroller or a 32 bit atmel arm.
The arduino uno is an open source microcontroller board based on the microchip atmega328p microcontroller and developed by arduinocc. Arduino is a single board microcontroller meant to make the application more accessible which are interactive objects and its surroundings. Adafruit industries unique fun diy electronics and kits adafruit metro 328 fully assembled arduino ide compatible atmega328 id.
The code can easily be changed to make the buttons perform other actions by consulting the mapping tables in the usb hid documentation. 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. Here is a diagram of the circuit created with fritzing.
I was looking for some type of touch screen for the arduino when i ran across this little gem on ebay. Open source electronic prototyping platform enabling users to create interactive electronic objects. 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.
Id like to start compiling information about the screens people are using. The following two examples both use three buttons connected to the arduino. 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.
Arduino can interact with buttons leds motors speakers gps units cameras the internet and even your smart phone or your tv. The processor has plenty of gpio analog inputs hardware uart spi and i2c timers and pwm galore just enough for most simple projects. Learn electronics and programming with arduino the arduino boards can be used as the brains behind almost any electronics project.
50 we sure love the atmega328 here at adafruit and we use them a lot for our own projects. Connect three wires to the board. The board has 14 digital pins 6 analog pins and programmable with the arduino ide integrated.
