Arduino to Arduino Serial Communication - Robotic Controls
Feb 6, 2013 · One option is to turn everything sent from the Sender Arduino into characters and then have the Receiver Arduino read in the characters. The data is actually sent as bytes, but the Arduino can convert from characters to bytes and vice versa.
Using Serial.read() with Arduino - Programming Electronics …
In this lesson, you’ll learn exactly how to use Serial.read () to receive data from the serial port and stitch it together as one value. We’ll cover this in two parts. Let’s take a step back from Serial.read (), and talk about serial communication. What is serial data?
Simultaneously reading data from multiple serial ports
My question here is how can I simultaneously read out all the data from the different serial ports on the arduino mega sketch. static char buffer[20]; int count =0; void setup() . Serial.begin(115200); Serial2.begin(115200); Serial3.begin(115200); delay(50); void loop(){ for(count=0; count<10; count++){ buffer[count] = Serial.read();
Arduino-to-Arduino Communication (via Serial Connection)
Jan 12, 2020 · * This program is part of a tutorial that shows how to communicate from an Arduino to another Arduino via a serial connection. * The status of a tact switch is sent to the other Arduino. If the switch is pressed, an LED is turned on. * This program has to be transferred to both Arduinos in order to make the application work. */
How to send and read String over serial between two Arduinos?
The problem is: how to read that String as a String on the other Arduino. I've tried to read each byte of the String and create a char array with the values, and then, convert it back to String. However, there are some bug I can't explain. I tried to change the delay () time and it worked at first, but then, the numbers got random or something.
