![]() ![]() void setup () Code language: Arduino ( arduino ) Example Code Using the NewPing Library 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.

You have successfully uploaded your first sketch to your board.The Ground and the VCC pins of the module needs to be connected to the Ground and the 5 volts pins on the Arduino Board respectively and the trig and echo pins to any Digital I/O pin on the Arduino Board.The LED labeled L near pin 13 should now blink slowly.Wait for the “Done uploading” message in the bottom blue status bar.Upload the sketch: File > Upload to I/O Board.If you do not know which one this is, you can find out by going into Device Manager > Ports (COM & LPT), and look for a “USB Serial Port (COMx)” This is the serial port for the board’s built-in FTDI. Select the serial port: Tools > Serial Port.Select the Mega 2560 board: Tools > Board > Arduino Mega 2560.Open the LED blink sketch: File menu > Examples > Basics > Blink.You should now see the LED labeled ON near the reset button light up.“C:\arduino-0022\drivers\FTDI USB Drivers” If your computer prompts for drivers, point it to the “drivers\FTDI USB Drivers” subfolder of the Arduino software, e.g.Connect the other end of the cable into a USB port on your PC/Mac.Connect the USB-B end of the cable into the board.Unzip the zip file to somewhere like C:\ (on Windows), so you will end up with a folder like C:\arduino-0022.Get the Arduino software if you have not already.Downloads: OSEPP™ Mega 2560 Schematic (PDF) The Creative Commons Attribution Share-Alike License. This board is based off of the Arduino Mega 2560 designed by Arduino, and is released under The input and/or output pins are brought out to headers which enable a convenient way to prototype projects without the need of soldering or desoldering. To prevent damage to the computer’s USB port, the fuse will trip when the current to the port exceeds 500 mA. There is an ICSP (In-Circuit Serial Programming) header for the ATmega2560 to optionally replace the bootloader.Īs an added precaution, the board comes with a resettable polyfuse on the USB connection path. The ATmega2560 comes with the Arduino bootloader preloaded. Compatible with the Ethernet and Motor Controller Shields.Compatible with existing Arduino software libraries.ICSP header for programming microcontroller.Flexible power source (USB or DC power).Connects to a computer via a standard USB cable.8x more flash and 4x more SRAM and EEPROM than the Uno.8-bit AVR RISC-based microcontroller running at 16 MHz.Added Molex connector for easy connect to OSEPP™ sensors and other I2C devices.Ĥ.23 x 2.13 x 0.61 inches (107.5 x 54.0 x 15.5 mm).Replaced USB-B connector with more popular mini-USB connector.This board is perfect for projects that require a lot of inputs/outputs or that require more complex programs that cannot fit into the smaller memory of the ATmega328P. The OSEPP™ Mega 2560 R3 Plus is the bigger brother to the OSEPP™ Uno board with more flash memory, more SRAM, more EEPROM, and more pins. Production for the MEGA 2560 has ceased as of June 2016. ![]()
