Then we're gonna implement the strategy in Arduino code.Īs a bonus, you'll learn how to convert serial data We'll talk about Serial.read and Serial.available.įor reading in data from the serial port. How to use Serial.read to receive data from the serial portįirst, we're gonna talk about the big picture How do you use Serial.read to receive the data That's sending data via serial to your Arduino board. Or maybe you've got a program running on your Raspberry Pi Maybe you're using the Arduino serial monitor window BONUS: How to convert the serial data from a string to an integerĪre you trying to use Serial.read to get data from a serial port to your Arduino?.Implementing the strategy in Arduino code.
Developing a protocol and strategy for reading in data from the serial port.The big picture of serial communication.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. The problem is, a lot of coders then go off to learn all about the exciting stuff that goes beep and boop without getting a firm grasp of how serial communication really works and why it’s important. Serial communication is a great way to see what’s going on after you compile and upload a new sketch, and it gets some early runs on the board. Most people stumble across the Arduino Serial.read() function pretty early on in the Arduino learning curve. Get 10 tips every new Arduino coder should know ➜
