Arduino pin diagram explanation. Making this pin low resets the microcontroller. How to use arduino nano. Each pin can provide or receive a maximum of 40 ma and has an internal pull up resistor disconnected by default. 5v 47v 53v vcc.
You can assume it as the brain of your board. Vin 33v 5v gnd. The arduino uno is arguably the most popular arduino board currently available. This arduino uno pinout diagram reference will hopefully help you get the most out of this board.
The main ic integrated. Rotate the potentiometer knob forward and backwards to adjust the lcd contrast. They operate at 5 volts. Weve created a well explained diagram based pin out representation of arduino nano.
In addition to the specific functions listed below the digital pins on an arduino board can be used for general purpose input and output via the pinmode digitalread and digitalwrite commands. The arduino uno board has six analog input pins a0 through a5. Maximum current draw is 50ma. 33v supply generated by on board voltage regulator.
16x2 lcd pinout diagram. The best way is to use a variable resistor such as a potentiometer. Pwm signals are. Power supply analog and digital pins and icsp.
All you need the arduino ide an usb cable and your nano board itself. These special functions and their respective pins are illustrated in the arduino nano pin diagram shown above. In this guide learn about arduino nano pin outs and diagrams. The output of the potentiometer is connected to this pin.
Input voltage to arduino when using an external power source. Selects command register when low and. The nano board weighs around 7 grams with dimensions of 45 cms to 18 cms l to b. Regulated power supply used to power microcontroller and other components on the board.
It will hardly take 5 10 minutes to upload you first program to arduino nano. The arduino uno pinout guide includes information you need about the different pins of the arduino uno microcontroller and their uses. All general purpose input output pins can be used to generate pwm except digital input pins from gpio pins 34 39. Arduino uno pin diagram click the image to enlarge it pin description.
When you want to monitor change across any pin you can use this pin as an interrupt instead of repeatedly monitoring the state of this pin. Each of the 14 digital pins on the arduino uno can be used as an input or output using pinmode digitalwrite and digitalread functions. This article discusses about. The guide also discusses different communication protocols used by the arduino and a detailed diagram of the arduino uno board.
Because these pins cannot be used as digital output pins. Each arduino board has its own microcontroller 11. Home arduino arduino uno pinout.
