HOW TO TEST SERIAL CONNECTION ARDUINO SERIAL

Now you can connect a variable resistor with the Sender Arduino and try to send its value to the receiver Arduino and then print on the Serial monitor. Make sure the Sender Arduino is powered up using a cable, adaptor, or you can even use the Receiver Arduino to power up the Sender Arduino, for this you will need to connect 5volts from the Receiver Arduino with the Vin pin of the Sensor Arduino. Now, you can upload the codes, open the Serial monitor for the Receiver Arduino. But this time instead using the Serial.write() function we use the Serial.readBytes() function to read the data.

HOW TO TEST SERIAL CONNECTION ARDUINO CODE

The code of the Receiver Arduino is almost similar to that of the Sender Arduino.

This means we will need to write two programs, one for the Sender Arduino and the other for the Receiver Arduino. Now, to understand the concept of the serial communication between two Arduino boards, let’s use one Arduino board as the Sender and the other Arduino board as the receiver. Serial Communication between Two Arduino Boards, Programming: Make sure the grounds of both the Arduino boards are connected together. The RX of one Arduino Uno board is connected with the TX pin of the other Arduino board and similarly the TX pin is connected with the RX pin of the other Arduino board. You will only need three male to male type jumper wires to get started with the two Arduino Boards.

I would appreciate your support in this way! How to serially connect two Arduino Boards? I may make a commission if you buy the components through these links. Other Tools and Components if you want to checkout: Without any further delay, let’s get started!!! So that’s why I decided to write an easy to follow tutorial on the Serial Communication between two Arduino boards. For the beginners these tutorials are hard to follow. Serial communication between Lora and ESP8266Īrduino Serial Communication with GSM ModuleĪrduino Serial Communication with GPS Neo 6M ModuleĪrduino Serial Communication with Multiple DevicesĪbove are some of the intermediate and advanced level projects based on the one way and two way Serial Communication systems. Apart from the Serial communication between two Arduino boards you can also use the same concept in performing serial communication with all other serial supported devices like example,Īrduino Serial Communication with Nodemcu ESP8266Īrduino Serial Communication with Lora by Reyax technologiesĪrduino Serial Communication with 10.1” HMI LCDĪrduino Serial Communication with the Voice Recognition Module In this article I will also explain how to perform the Serial communication between Arduino Uno and Arduino Mega. I will start with the very basics and after you learn the basic concept of Serial communication, then I will take it to the next level and we will do some advanced level things. After reading this article, you will be able how to use the Serial.read() and Serial.wrtie() functions.

There are times when the single Arduino Uno or Arduino Mega, or any other Arduino board is not enough to complete the project, then in a situation like this you can Serial connect multiple Arduino boards. Although for most of the projects Arduino Uno or Arduino Mega is more than enough to design advanced level projects like CNC machines, 3D Printers, etc. Serial communication between two Arduino boards- In this tutorial, you will learn how to perform the Serial Communication between two Arduino boards.
