Arduino uno pin diagram with description. I have used arduino with hobby servos often but i was getting annoyed of the jitter of the standard servo library. The arduino board exposes most of the microcontrollers io pins for use by other circuits. Arduino tutorial i updated. To support the microcontroller.
1122013 notre dame design deck 2 first program. This is the new arduino uno r3. The processor has plenty of gpio analog inputs hardware uart spi and i2c timers and pwm galore just enough for most simple projects. Arduino uno is a microcontroller board based on 8 bit atmega328p microcontroller.
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. So i took my newly acquired rigol ds2072 and tried to figure out what was causing the servos to rattle and jitter.
I made a program or sketch for arduino uno controlling 20 servos. 50 we sure love the atmega328 here at adafruit and we use them a lot for our own projects. 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.
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.
