#Arduino mega serial1 pinout software

It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. I wrote the sketches for the Mega to poll the Nano and the Nano to reply if the data poll was for it. So be sure you have connected your xbee shield to the correct serial - e.g. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. I am attempting to communicate using MAX485 TTL to RS-485 Modules I purchased with an Arduino MEGA and NANO. On older boards (Uno, Nano, Mini, and Mega), pins 0 and 1 are used for communication with the computer. All Arduino boards have at least one serial port (also known as a UART or USART), and some have several. The HC-05 zs-040 modules have a voltage regular on then vcc in line. Description Used for communication between the Arduino board and a computer or other devices. I have the TX on the HC-05 connected to pin 19 (RX1) and the RX from HC-05 connected to pin 18 (TX1), as well as power connected.

I have ended up trying to use this Instructable adapted to a Mega 2560. Copy the Below code then upload it on your Arduino / PINOUT: RC522 MODULE Uno/Nano MEGA SDA D10 D9 SCK D13 D52 MOSI D11 D51 MISO D12 D50 IRQ N/A N/A GND GND GND RST D9 D8 3.3V 3.3V 3.3V / / Include the standard Arduino SPI library / include / Include the RFID library / include phamb587: I am using Mega 2560 and I use Serial.write () to send data to laptop via USB Cable and Serial1.println () to send data to other computer via bluetooth. Only Serial outputs to the Serial monitor.

I have followed a few guides, but havent gotten 100 working so far. Thats because Serial1 does not output to the Serial monitor. In the below example I using serial1 to talk to the HC-05. I am trying to use a HC-05 module with a Mega 2560. Copy the Below code then upload it on your Arduino / PINOUT: RC522 MODULE Uno/Nano MEGA SDA D10 D9 SCK D13 D52 MOSI D11 D51 MISO D12 D50 IRQ N/A N/A GND GND GND RST D9 D8 3.3V 3.

The Arduino Mega has three additional serial ports: Serial1 on pins 19 (RX) and 18 (TX), Serial2 on pins 17 (RX) and 16 (TX), Serial3 on pins 15 (RX) and 14 (TX). The Arduino Mega has 4 hardware serial channels so we do not need to use software serial, we can use one of the extra hardware serials to talk to the Bluetooth module. Have in mind the default baud rate for the mDot is 115200 and unless you have changed it you should use that.
