There are easy ways of getting more I/O pins for any project; shift registers, I2C expanders, or ADCs will give you plenty of pins for whatever project you have in mind. All these require extra com… ...

This code is written for Arduino and provides functions for configuring digital input and output pins. The code defines some constants (HIGH, LOW, OUTPUT, and INPUT) and three functions that are used ...

The Arduino Mega's PWM pins are digital output pins located on D2 to D13 and D44 to D46, coming to a total of 15. While they function as normal digital pins that can switch a component either ...

const int trigIn = A3; // Pin connected to the button and the trig in jack //const int clipLed = 13; // Pin connected to the LED const int trigLed = A5; // Pin connected to the LED const int ...

If you are only concerned about using Arduino IDE functions, all you need to worry about are the Arduino pin numbers. But if you want to program using the corresponding microcontroller’s pin numbers, ...

The basic functions of the Arduino IDE – pinMode, digitalRead, digitalWrite, and analogRead – are available. Most of the WiFi functions work just like the WiFi shield library.

The Arduino Mega's PWM pins are digital output pins located on D2 to D13 and D44 to D46, ... function. This function takes in the pin number and any value from 0 to 255.
