Arduino uno pin diagram with description. The processor has plenty of gpio analog inputs hardware uart spi and i2c timers and pwm galore just enough for most simple projects. Arduino tutorial i updated. Arduino uno is a microcontroller board based on 8 bit atmega328p microcontroller. So i took my newly acquired rigol ds2072 and tried to figure out what was causing the servos to rattle and jitter.
In addition to all the features of the previous board the uno now uses an atmega16u2 instead of the 8u2 found on the uno. The diecimila duemilanove and current uno provide 14 digital io pins six of which can produce pulse width modulated signals and six analog inputs which can also be used as six digital io pins. 12 thoughts on click here arduino robot kit wiring diagram carvarsa january 3 2013 at 546 pm. The arduino board exposes most of the microcontrollers io pins for use by other circuits.
To support the microcontroller. Arduino nano arduino pro mini arduino mega arduino due arduino leonardo. Now you are going to write your first program which will blink an led on pin 5 when pin 2. I have used arduino with hobby servos often but i was getting annoyed of the jitter of the standard servo library.
These pins are on the top of the board via female 01 inch 254 mm headers. Sainsmart 1602 lcd shield module display v3 for arduino uno r3 mega2560 nano due. Adafruit industries unique fun diy electronics and kits adafruit metro 328 fully assembled arduino ide compatible atmega328 id. Along with atmega328p it consists other components such as crystal oscillator serial communication voltage regulator etc.
