![]() You can find example sketches in the Arduino IDE at File > Examples and the tutorials that go with them here: docs.arduino. I tried each one of them and it's working fine. You should probably start with some simple experiments to get acquainted with programming and electronics. Arduino Problem with using SoftwareSerial and SPI Ask Question Asked 6 years, 5 months ago Modified 4 years, 3 months ago Viewed 2k times -1 I am using an external ADC (via SPI) and also a GPS receiver (Software Serial). Nobody would ever use software serial if they had the option to use hardware serial.Įssentially I want to be able to pass audio to the bluetooth module from an iPhone/Android phone and I have no idea where to start on a Due. That doesn't mean you need software serial, it's just all they had to work with. For that reason if you need to communicate with an accessory device over serial using an Uno it makes sense to use software serial. The Uno only has one hardware serial port, which is used for communication with the computer over the USB connection, including for uploads. The most common Arduino board is the Uno and so many of the tutorials you find are written for Uno. I see a lot of different examples online for the different types of things I want to do for my project, but a lot of them point out that I need SoftwareSerial.
