What are different types of Arduino® pins?
Arduino® is a brand of programmable microcontroller, which is often used by fans to interact with other devices. In projects such as robotics and home automation, Arduino® boards are commonly connected to sensors, buttons and engines. PINS Arduino® allows users to easily connect different devices and components to the microcontroller. There are three main types of Arduino® pins: digital pins, analog pins and power pins. This means that one PIN can send and receive digital data. Arduino® digital pins can only be "high" or "low". When the digital pin is high, there is a constant voltage. When the pin is low, this tension is gone. One common examples of digital output is to turn on and off the light emitting (LED) and check the status of the button is an example of a digital input.
In addition to providing simple inputs and outputs, you can also use Digital Arduino® pins for many boards for modulation of pulse width (PWM). Pulses width modulation is used toSimulation of changing analog output using digital pins. For example, if the engine is connected to the digital output pin, it would rotate when the pin was brought high and stopped when the pin was low. For PWM, the digital output pin is switched faster or slower to change the speed of the engine. Pulse width modulation causes Arduino® digital pins to switch high and low so quickly that the connection behaves as an analog output and the resulting voltage can be precisely checked.
Arduino® Microcontrollers also have analog input pins. Like digital input pins, they are used to read the attached device, such as a sensor. Although digital pins can only determine whether the connection is high or low, the Arduino® analog input pins are ABLE to read the exact voltage value. This is useful for connecting to analog sensors that have a wide range of possible values. For example, an analog thermometer often sends voltage to, toTeré corresponds to the temperature. Using an analog input pin, Arduino® can read the value directly.
The final type PIN Arduino® is a power pin. Most Arduino® microcontrollers have several pins that receive and issue different voltages. One of the most important is the "voltage in" (VIN). This pin is used to ensure a constant voltage to power the board from an external power or battery. Five V (5V) power pins allow components and sensors to receive a regulated five cotton power directly from the microcontroller. Finally, the GND power pins can be used to electric ground equipment connected to the Arduino®.
