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,...
There is a considerable amount ofdifference between the Arduino Nano and the Arduino megaas the processor used itself is different. Arduino Mega is more powerful than an Arduino Nano in terms of speed and number of I/O pins. As you might guess, the size is also bigger than an Arduino UN...
Now we need to make a connection between the 5V pin of Arduino and the relay module’s positive (+) pin. Connect the GND pin of Arduino to the relay module’s negative (-) pin. Now the connections between UNO board & relay module are completed. Step2: Relay board wiring to the Suppl...
I have included a detailed specification, pin diagram, and code for SPI communication between two Arduino boards. I have also included Arduino SPI read example with the RFID-RC522 reader. After this article, you will learn how to use the SPI protocol and read/write data via the SPI protocol...
Bobuino: Basically an Arduino UNO pinout setting. This pinout version is great for use with shields or code that's written for the Arduino UNO, as the pin functions stay the same (MOSI on D11, MISO on D12, SCK on D13). Sanguino: This pinout is common on older 3D printer controllers...

Arduino UNO, MEGA2560 and NANO are the most common boards, but many others are available. Each has its own specification, which will become of greater importance as a maker’s knowledge increases. Size may be a consideration if the goal is to build the board into, say, a robot or other...
I have tried the same at my end with the Arduino Uno, which is 5V device. It means, whenever I will trying the toggle the GPIO pin to high and low, the voltage will vary 5V to 0V respectively. And this is out of specification mentioned in the datasheet. And this can d...
This library can be quite heavy on small systems, especially if the fairly small ATmega 328p (such as in the Arduino Uno) is used. In the default configuration, the available 32K flash space is nearly filled up (this includes some debug output overhead, though). By disabling some features...
The operation is shown in the diagram belowThe function generated by the code is: countPulseASM From the C part of the code we have the following prototype (or function definition): unsigned long pulseIn(uint8_t pin, uint8_t state, unsigned long timeout) ...
