it consists of other components such as crystal oscillator, serial communication, voltage regulator, etc. to support the microcontroller. This article explores theArduino UNO pin diagramin detail along with basics on how to use this board and upload your first...
Arduino Uno R3 Pin Diagram TheArduino Uno R3 pin diagramis shown below. It comprises 14-digit I/O pins. From these pins, 6-pins can be utilized like PWM outputs. This board includes 14 digital input/output pins, Analog inputs-6, a USB connection, quartz crystal-16 MHz, a power jack,...
Each of the 14 digital pins on the Uno can be used as an input or output, usingpinMode(),digitalWrite(), anddigitalRead()functions. They operate at 5 volts. Each pin can provide or receive 20 mA as recommended operating condition and has an internal pull-up resistor (disconnected by defa...
The Uno has 6 analog inputs, labeled A0 through A5, each of which provide 10 bits of resolution (i.e. 1024 different values). By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the AREF pin and the analogReference() fun...
Arduino Mega Pin Diagram Arduino Mega Pin Configuration Controller Pins: RESET:(Reset input) A low level on this pin for longer than the 4 clock cycle will generate a reset. Arduino Mega has inbuilt reset circuit with push button to reset system and this pin can be used by other devices ...
After uploading is done, Disconnect the Arduino and proceed to connections as below: (Refer the pin diagram of 2560 IC provided in step 1) UNO pins -> ATMEGA2560 pins 10 -> 30 11 -> 21 12 -> 22 13 -> 20 5v -> VCC (in my case pin 10) ...
example to interface AT24C02 EEPROM with Arduino. Almost all Arduino development boards have at least one I2C port. Similarly,Arduino Unoalso has one I2C port which we can use to write and read data from this EEPROM chip. Connect the Arduino and EEPROM as shown in the interfacing diagram ...

74HC595 Pinout Diagram If you look for 595 series shift registers, it has many variants and models available in the market. But all work the same way. They have the same pin configuration, electrical features, pinout diagram, and working principle. But this tutorial will be more focused on ...
This configuration is found on the “standard” baseline Arduino boards built between 2007 and 2012. Boards using the newer “extended” pin layout (the Uno R3 and Leonardo), as well as the “Mega” boards, also support the baseline connections, but add new capabilities by extending the rows...
