Software Serial is also named as Virtual Serial Port. It’s really very comfy if you are working on serial modules. IF you ask me I have never used hardware serial port because pin # 0 and pin # 1 are also used for uploading code and debugging the code via Arduino Serial Monitor. So, I always connect my Serial modules via software serial and then check their output on Serial Monitor. So, let’s get started with How to use Arduino Software Serial:
How to use Arduino Software Serial ?
- I am gonna use Proteus software for testing the codes. So you can download the Proteus Simulation by clicking the below button:
- First of all, let me tell you where you can find Examples of Software Serial.
- Arduino has a Library of Software Serial in it. If you can’t find its library then you should download the Software Serial Library.
- Now copy and paste the below code in your Arduino:
SoftwareSerial SoftSerial(2, 3);
SoftSerial.println(" **** Its a Software Serial **** ");
SoftSerial.println(" Designed by www.TheEngineeringProjects.com");
Serial.println(" **** Its a Hardware Serial **** ");
Serial.println(" Designed by www.TheEngineeringProjects.com");
char data = Serial.read();
- In the above code, we have first included the Arduino Software Serial Library using #include<SoftwareSerial.h>.
- After that, I have created the SoftSerial object and its parameters are SoftSerial(RX, TX), so in the above code pin # 2 has become RX of our Arduino Software Serial and pin # 3 become TX.
- Now our SoftSerial object is ready so next thing we have done is SoftSerial.begin(9600), here we have started our software serial and the baud rate set is 9600.
- Now design a small circuit in Proteus, you will need Arduino Library for Proteus to use Arduino in Proteus, as shown in below figure:
- Now get our Arduino Hex File and upload it in your Proteus.
- Now run your Proteus Simulation and you will get something as shown in below figure:
- So, its printed there that one is hardware serial and second is software serial and you can see the software serial is connected to Pin # 2 and Pin # 3.
- Now when you write something in the Hardware Serial, it will also get printed in the Software Serial, that’s the code which we have added in the loop() section.
- The below videos will give you better idea of how it’s working.
So, that’s all for today, I hope you have enjoyed this Arduino Software Serial example. Download the Simulation from above button and try to design it on your own. Take care and have fun !!! 🙂
