Some of the boards that support multiple hardware serial ports, such as the Leonardo, Mega, and Mega 2560, have restrictions on which pins you can use for SoftwareSerial receive (RX). Even though we aren’t using the receive capability here, and even though you’d most likely use the har...
// On Arduino MEGA, the following PINS support analogWrite: 2-13, 44-46 // If all PINS support analogWrite are occupied, turn gbolVSpeed = false, which means that the Motor will run in FULL speed. bool gbolVSpeed = true; // Direction of the Motor, 1 or -1 int gintDir = 1; /...
// Location of true interrupt pins: // Uno: pins 2 and 3 // Mega 2560: pins 2, 3, 21, 20, 19, and 18 // Since there are only 6 true interrupt pins, use Good Performance if there are 4 motors // Bugs for a particular Arduino Mega 2560 // If mB use 34 as Dir pin and m...
When you look at the network board, there are six rows of two pins. There is a legend above and below this block of pins. In the diagram show, "5V" in the legend corresponds to the first pin the first row, while "ST" refers to the second pin in the fourth row. When you look ...
Use the two analog pins, A4 and A5, as shown in the table above. I2C Between 2 Arduino’s For our first experiment we will hoo two Arduinos together and exchange data between them. One Arduino will be the master, the other will be the slave. I’m using two Arduino Unos, but you ...
(Tx) and receive (Rx) pins of the CO2sensor are connected to the serial port of the microcontroller to transmit and receive CO2data from the sensor to the microcontroller and vice-versa. Thereafter, the sensor is activated and 100 data packets are obtained every second (i.e., the sampling...
Supported boards, output modes and default pinsTable is not necessarily complete. Abbreviations explained below the table. The default output mode is in bold for each row. If stereo is supported, in a mode, the cell PWM-1 has two numbers with the second pin number is given in parentheses ...

I try my Mega with the original config.h and the Uno’s config.h too… I tried several tx/rx on the card, the Mega don’t works with Nextion…. Have you some ideas to help me ? (I wait to receive a new Mega to see if my actual Mega have a problem with tx/rx pins…) Than...
