2/20/2023 0 Comments Arduino mega pwm![]() ![]() Whereas this Arduino tutorial for beginners covers some parts of the Arduino Uno hardware, the Ultimate Arduino Uno Hardware Manual covers a lot more. Refer to the Ultimate Arduino Uno Hardware Manual for diagrams that show the multiple pin functions of Arduino Uno boards. Analog pins at the bottom right of the Arduino Uno are also configurable as digital pins. These are known as TWI or I2C, and SPI pins. In addition to the marked pins, there are actually other communication pins. Arduino Uno Digital Input Output Pins, PWM Pins and Communication Pins In addition, the two pins at the top right of the below image are for serial communications. Digital pins are configurable as input pins or output pins. ![]() Some of the the digital pins have PWM capabilities. The following image marks the Arduino Uno digital pins. Arduino Uno Digital Input Pins, Output Pins, and PWM Pins Input/output is often written I/O for short. Digital pins that are configurable as either inputs or outputs are called input/output pins. The following subsections highlight the main Arduino Uno and Arduino MEGA 2560 pins. In addition the basics of PWM pins are explained. This part of the tutorial includes more details on digital input and output pins. Digital Arduino input and output pins are briefly covered in part 8 of this tutorial on how to use a push button switch with Arduino. Thirdly some pins have special functions such as serial communications and PWM (Pulse Width Modulation). Secondly as an output to switch or drive an electric load such as an LED. Firstly input pins for reading the state of a pin, or attached switch for example. ![]() Basically, Arduino digital pins are configurable between three different functions as follows. ![]()
