What is din and dout?

The DIN and DOUT pins refer to the data pins. However, the difference between these two pins is the data direction. DOUT pin is an output pin which sends the ADC data. This pin is used for recording purposes. By other hand, DIN pin is an input pin which receives the DAC data.

What is MCP3208?

The MCP3208-CI/P is an 8 channel, 12bit Analogue to Digital Converter (ADC) with SPI interface in 16 pin DIP package. This ADC combines high performance and low power consumption in a small package by making it as an ideal for embedded control applications.

What are digital pins and analog pins?

Analog pins are the ADC (analog to digital converter) input pins. They are used for reading analog voltage (between 0-5V on arduino, by default). Check out the sample program for analogRead() command. Digital pins are used mainly as output pins.

What is the difference between analog and PWM pins?

The Arduino can input and output analog signals as well as digital signals. An analog signal is one that can take on any number of values, unlike a digital signal which has only two values: HIGH and LOW. The function used to output a PWM signal is analogWrite(pin, value). pin is the pin number used for the PWM output.

Are PWM pins analog?

The Arduino does not have a digital-to-analog converter (DAC) built-in, but it can do pulse-width modulation (PWM) a digital signal used to achieve some of an analog output’s functions. The function analogWrite(pin, value) is used to output a PWM signal. The pin number used for the PWM output is pin.

What are analog pins used for?

What is the purpose of PWM pins?

PWM stands for Pulse Width Modulation and it is a technique used in controlling the brightness of LED, speed control of DC motor, controlling a servo motor or where you have to get analog output with digital means.

What do PWM pins do?

Pulse Width Modulation, or PWM, is a technique for getting analog results with digital means. Digital control is used to create a square wave, a signal switched between on and off. To get varying analog values, you change or modulate, that pulse width. …

Can analog pins be used as digital?

The analog input pins can be used as digital pins, referred to as A0, A1, etc. The exception is the Arduino Nano, Pro Mini, and Mini’s A6 and A7 pins, which can only be used as analog inputs.
