How To Use Arduino’s Analog and Digital Input/Output (I/O ...

· The Arduino does not have a built-in digital-to-analog converter (DAC), but it can pulse-width modulate (PWM) a digital signal to achieve some of the functions of an analog output. The function used to output a PWM signal is analogWrite(pin, value). pin is the pin number used for the PWM output. value is a number proportional to the duty cycle of the signal. When value = 0, the signal is ...

digitalWrite() - Arduino Reference

· Write a HIGH or a LOW value to a digital pin. If the pin has been configured as an OUTPUT with pinMode (), its voltage will be set to the corresponding value: 5V (or on boards) for HIGH, 0V (ground) for LOW. If the pin is configured as an INPUT, digitalWrite () will enable ( HIGH) or disable ( LOW) the internal pullup on the input pin.

Interfacing of MQ-135 Gas Sensor with Arduino

· When no gas digital output is 1 and analog output gives 1023 max value. When gas is present digital output is 0 and analogue output is much less than 1023. Using potentiometer on chip we can control the turning OFF point of digital pin at some value of analog pin. The sensor needs a load-resistor at the output to ground. Its value could be from 2kOhm to 47kOhm. The lower the value, the …

The Full Arduino Uno Pinout Guide [including diagram]

Arduino Uno Pinout - Digital Pins. Pins 0-13 of the Arduino Uno serve as digital input/output pins. Pin 13 of the Arduino Uno is connected to the built-in LED. In the Arduino Uno - pins 3,5,6,9,10,11 have PWM capability. It’s important to note that: Each pin can provide/sink up to 40 mA max. But the recommended current is 20 mA.

digitalRead() - Arduino Reference

· Notes and Warnings. If the pin isn’t connected to anything, digitalRead () can return either HIGH or LOW (and this can change randomly). 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.
