This is not a major limitation, it can be overcome using level shifting circuits. The ATMega2560 uses 5V logic levels, so it might not be compatible with 3.3V sensors and other peripherals. The GPIO pins are also mapped internally to the peripherals like SPI, USART, and SPI. The easiest to use is the Arduino Mega board, which contains the ATMega3560, and can be programmed over USB from the Arduino software. It can be programmed using Atmel Studio and a dedicated programmer, or using another ATMega microcontroller and using the Arduino development environment. The ATMega2560 is an 8-bit AVR microcontroller that comes with 86 programmable GPIO pins, PWM, ADC, and timer peripherals. Note: Complete technical details can be found in the ATMega2560 datasheet given at the end of this page.
NewPing sonar (TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE) // NewPing setup of pins and maximum distance.The ATMega2560 from Atmel is an 8-bit low-power microcontroller that is found in the popular Arduino Mega development board. Here’s an example code: # include # define TRIGGER_PIN 9 # define ECHO_PIN 10 # define MAX_DISTANCE 400 // Maximum distance we want to measure (in centimeters). Using the NewPing library we can get the distance with just a single line of code. Then according to those results we calculated the distance based on it.

In the previously explained code we manually triggered the sensor and measured the received signal pulse duration. There are actually a simpler and better way to program the Arduino to measure distance using the HC-SR04 ultrasonic sensor, and that’s using the NewPing library. void setup () Code language: Arduino ( arduino ) Example Code Using the NewPing Library
#2560 pinout serial#
In the setup we have to define the trigPin as an output and the echoPin as an Input and also start the serial communication for showing the results on the serial monitor. Int distance Code language: Arduino ( arduino ) defines pins numbers const int trigPin = 9 Then we need a Long variable, named “duration” for the travel time that we will get from the sensor and an integer variable for the distance. In this case they are the pins number 9 and 10 on the Arduino Board and they are named trigPin and echoPin. } Code language: Arduino ( arduino ) Code Explanationįirst we have to define the Trig and Echo pins. Prints the distance on the Serial Monitor Serial. Reads the echoPin, returns the sound wave travel time in microseconds Sets the trigPin on HIGH state for 10 micro seconds digitalWrite(trigPin, HIGH) Clears the trigPin digitalWrite(trigPin, LOW) begin( 9600) // Starts the serial communication PinMode(trigPin, OUTPUT) // Sets the trigPin as an Output pinMode(echoPin, INPUT) // Sets the echoPin as an Input Serial. */ // defines pins numbers const int trigPin = 9 Ultrasonic Sensor HC-SR04 and Arduino Tutorial Here’s a code for measuring distance using the HC-SR04 ultrasonic sensor and Arduino.
