The code defines some constants (HIGH, LOW, OUTPUT, and INPUT) and three functions that are used to configure the DDRx, PORTx, and PINx registers that control the digital pins on an Arduino board.

Pin (DB4 – DB7) on the LCD to the digital pins 6, 5, 4, 3 of the Arduino. Pin 15 (LED) on the LCD to 5V pin on the Arduino. Pin 16 (LED) on the LCD to ground on the Arduino through the 200-ohm ...

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 ...

Next, I defined the total number of LEDs, colour order of LED type, Arduino pin for data input, and push-button pins. #define NUM_LEDS 42 #define COLOR_ORDER RGB #define LED_PIN 6 #define MIN_PIN 4 ...

This sensor has three pins, two of which are power pins leveled VCC and GND and the other two pins are analog and digital pins which are shown in the diagram above. It has an onboard power LED and a ...

Connect the RS and E pin of the LCD module to the pin2 and pin3 of the Arduino board respectively. The RW pin of the LCD is connected to the ground. As we will use the LCD module in 4-bit data mode, ...

Learn the advantages and disadvantages of using analog and digital sensors with Arduino for mechatronics projects. Find out how to interface, calibrate, acquire, troubleshoot, and select sensors ...

Arduino Code for Digital Thermometer. The code for temperature measurement using LM35 is described here. A library for the LCD unit is included and then data and control pins for the LCD and ...
